Mariah Stolfi: Lost 84 Lbs.
A self-described "binge eater," Mariah Stolfi reached 150 lbs. by the 5th grade.
The Wisconsin native also struggled with health issues. In her early teens she was diagnosed with polycystic ovarian syndrome (PCOS) and sleep apnea. “It is extremely difficult to lose weight and maintain weight loss with PCOS,” says Stolfi, who hit her highest weight of 286 lbs. at age 18. “And the lack of good sleep caused me to be lethargic, which meant I didn’t have the energy to work out.”
In July 2017, Stolfi, 19, decided to undergo vertical sleeve gastrectomy surgery.
Now down 84 lbs. – she hopes to lose an additional 60-70 lbs. – she is sharing her journey on social media.
“Once I discovered the weight loss surgery Instagram community I knew I had to be a part of it,” says Stolfi, whose candid photos and videos have garnered her more than 14,000 followers on Instagram and YouTube combined.
As for her best advice to those struggling with their weight: “This journey is 80 percent mental and 20 percent physical. If you don’t fix your mindset you will not succeed on your weight loss journey.”

Kathleen Golding: Lost 178 Lbs.
Growing up, Kathleen Golding had always been overweight. By 21, she had turned to food as a "coping mechanism" while wrestling with anxiety and depression.
"I was stuck in a constant cycle of daily binging," the New Bern, North Carolina resident, whose highest weight was 331 lbs., tells PEOPLE. "I was eating fast food for every meal and enormous quantities each time."
She finally decided to make a change and turned to gastric bypass surgery, which she underwent in June 2016.
“For some reason, weight loss surgery is seen as 'cheating' or being weak, but for me, I found strength in being able to say 'I can’t do this on my own. I want to be healthy, but I need help,'" says Golding, now 26.
After the surgery, the weight began to "melt off," says Golding, who eventually dropped 178 lbs. by making healthy dietary changes and exercising.
Now, Golding says she is finally at peace with her body. "I have some loose skin and it definitely has its imperfections, but I worked hard for this body," says Golding, who also documented her weight loss journey on Instagram. "I spent so much time hating it but I’ve realized that this is the only body I’ve got and I’m going to take care of it."

Bonnie Wiles: Lost 162 Lbs.
Growing up, Bonnie Wiles ate a lot of starchy foods, and by 18, she was over 200 lbs.
"I tried diets but kept gaining weight after getting married and having four children," Wiles, 58, tells PEOPLE in the 2018 Half Their Size issue. "It wasn't until my first grandson was born in 2011 that I committed to get healthy."
The Fayetteville, Arkansas, resident joined TOPS, a weight loss support group, and started using MyFitnessPal.
"It tells me if I'm overeating and helps keep track of how much I walk—usually 50 miles a week," says Wiles, now 148 lbs.
And she is loving her new lifestyle.
"When I was heavy, I had to ask for a seatbelt extender on a plane. Now I can't wait to go with my family to Hawaii, where I can show off my favorite body part—my arms."

Jeremiah Peterson: Lost 92 Lbs.
After a family hiking excursion proved too taxing for his 290-lb. frame, Jeremiah Peterson decided to change his lifestyle.
"I remember being bent over heaving just trying to catch my breath," the Missoula, Montana-resident tells PEOPLE. "When I looked up, I saw my wife and three kids [10, 8 and 7] easily hiking, talking and laughing with each other — without me. It was a hard-hitting moment."
He entered a transformation challenge for motivation. Then, switched over to a keto-based diet consisting of healthy fats, lean protein and green vegetables, started taking twice-daily hour-long hikes, and lifting weights.
Peterson, now 198 lbs., ended up dropping 82 lbs. during the 150-day transformation contest, called the 1st Phorm Transphormation Challenge — and he won the $50,000 grand prize.
He says: "I feel like I have drive and ambition like I have never had before in my life — and I’m almost 40!"

Robin Janes: Lost 280 Lbs.
Janes, 28, can't remember a time when she was ever small. “Not even in a baby picture,” she tells PEOPLE for the 2018 Half Their Size issue. “I was always overweight, and it continued through adulthood.” By then, Janes couldn't fit on a normal scale. “I went to my friend’s family business where they weigh huge industrial tubs,” she recalls. “That’s how I found out I was 450 lbs.”
Her real turning point, though, was when she realized she could no longer fit in the desks at her college, and had to put her education on hold.
Ready for a change, Janes started with Isagenix meal replacement shakes, and taught herself to cook healthy meals. She also began working out slowly, with short walks and swims. Now 280 lbs. lighter, Janes loves playing volleyball and hitting the gym, and is working on her degree once again.
“I’m back in school. I can work anywhere. I’m not limited,” Janes says. “I feel like before all the doors were closed for me. Now they’re all open.”

Melody Perdue: Lost 180 Lbs.
As a child, food was one of the few constants in Perdue's life.
“My mother wasn’t able to raise me fully,” Perdue, 34, tells PEOPLE in the 2018 Half Their Size issue. “I always associated food with happiness. I thought, ‘Food is not going to leave me.’ ”
With a diet of six to eight chocolate bars a day, fried chicken and macaroni and cheese, Perdue was 308 lbs. by age 29, and was pre-diabetic, had sleep apnea and a mild form of polycycstic ovary syndrome. But it wasn't until a life-threatening car accident in 2012 that she decided to make a change.
“I was on my sister’s couch, and I sat there and I cried to God,” she recalls. “I said, ‘I’m sick and tired of feeling like this.’ ”
Perdue signed up for Optavia, a packaged meal plan, and learned how to eat balanced meals of a protein and three servings of vegetables. That along with 30-minute walks helped her lose 180 lbs.
“Now I have so much energy,” she says. “I was able to ride a bike for the first time at 33.”

Megan Rachow: Lost 170 Lbs.
Rachow, 30, remembers the exact day she decided it was time for a change.
“I had been living a life of obesity for a few years and was exhausted both physically and mentally,” the physical therapist tells PEOPLE. “I felt like I had gained so much weight that I would never get it back off. I still remember the day that the switch flipped for me — July 19, 2014 — and I decided I was done living like this.”
The Medina, Ohio, resident says until that point she was drinking five or more cans of soda a day, eating large quantities of food and stopping at the drive-thru daily.
“Exercise was out of the question as I could barely walk up the stairs to my apartment,” she says.
Spurred into action, Rachow says she started small, first cutting out soda and only eating food she cooked at home.
“The weight starting coming off,” she says. “I remember I lost 9 lbs. my first week. After I had lost 100 lbs., I started trying more adventurous exercise. I became fascinated by fitness and seeing what new things I could accomplish with my body. I do things that I never dreamed were possible like running races, lifting heavy weights, and completing a sprint triathlon.”

Mike Bauler: Lost 225 Lbs.
After Bauler's father-in-law went on life support following a heart attack in 2010, the Madison, Wisc., resident said he knew he needed to change his own ways.
“At this time I was 28, had two young boys, Eli (2) and Carson (6 months),” he says. “I recall all of the family standing around crying and sad. This was the trigger for me as I knew if I didn’t get my life together soon, I would be the next person in that hospital bed.”
A few weeks after his father-in-law was admitted to the hospital, Bauler, who weighed 450 lbs. at his heaviest, signed up at a local gym. He first focused on exercising and eventually made changes to his diet, sticking to 1,500 calories a day and smaller portion sizes for one year.
Now the 35-year-old runs everyday and has completed endurance competitions like Ironman and Ragnar.
“I lost most of my weight (200 lbs.) in about 18 months so I have had to stay busy to keep it off,” he says. “I am extremely competitive and have an amazing network of friends and the From Fat To Finish Line (FFTFL) community. I like to join training groups and training clubs because of the friendships and accountability it creates. It would be easy for me to blow off a 10-mile run at 5:30 on a Friday morning, but I know I have two friends meeting me, who I would never let down.”

Katia Powell: Lost 170 Lbs.
After reaching her highest weight of 350 lbs. at 26 years old, Boston resident Katia Powell realized her own health didn’t reflect her dreams of becoming a medical doctor.
Powell was overweight as a child, eating a diet full of processed foods and little water and vegetables. In college, Powell says she dramatically gained more weight. “I walked into my apartment, stared at my reflection in the mirror and asked, ‘Who is that?’ It was a defining moment for me,” says Powell, 38, who is now a holistic health practitioner and fitness trainer who has founded the company Black Girls Nutrition.
Powell joined her local YMCA, gradually increasing her workouts until she was going 4 to 5 days a week for 60 to 90 minutes. She also changed her eating habits, replacing sugary sweets with fresh fruit and vegetables. Within the first six months she lost 100 lbs., and has since lost another 70 lbs.
Powell, who has kept the weight off for 12 years, says she now loves cycling, dance and yoga, and “if I am unable to attend the gym, I run or take a walk outside, or workout at home and do a high intensity interval training. My workout routine also includes meditation,” she says.

Sara Cloutier: Lost 151 Lbs.
Cloutier, 36, always felt like an outsider growing up. She weighed 220 lbs. in high school, and never enjoyed shopping or playing sports with her friends.
“I cannot remember a time when I didn’t feel like I was the biggest girl in the group, and I hated it,” Cloutier tells PEOPLE for the 2018 Half Their Size issue. “I was always the odd one out.”
After her first pregnancy with her daughter in 2003, Cloutier hit 301 lbs., and was ready for a change. "I didn't want to die," she says. "I wanted to watcher grow up and give her healthy habits." By working out with a trainer and choosing healthier meals, she successfully lost 151 lbs., and maintained a healthy weight through her second pregnancy in 2008.
As she worked to get back into a postpartum fitness routine, Cloutier discovered Zumba, and fell in love with group fitness classes. Three weeks after her first class, she became a certified trainer, and started teaching classes. By 2013, the demand had gotten so large that she opened her own fitness studio, and now runs it along with her full-time job.
Cloutier is now getting ready for another big change — her third child.
“I’d be lying if I said I wasn’t concerned about gaining the weight back, because gaining weight is still scary, and having to purposely do it is scary,” she says. “But knowing the difference between a healthy pregnancy and an unhealthy pregnancy is huge.”
11 of 59
Katie Bolden: Lost 150 Lbs
Between her severe anxiety, depression and her weight — 280 lbs. at her heaviest — Bolden, 31, felt "ruined," mentally.
“I hated everything about myself, and that’s just a tough situation to be in," she tells PEOPLE for the 2018 Half Their Size issue.
Then at age 26, Bolden was diagnosed with polycystic ovary syndrome, and learned she would have trouble conceiving a child. And just a few years later, in Feb. 2013, she went partially blind in one eye, and found out she had pre-multiple sclerosis.
"It lit a fire in me," she says. “I just realized that I was just existing and wasting my life away, and it was time to do something and start living.”
Bolden started tracking everything she ate on MyFitnessPal, and took up swimming, hiking and weightlifting. After three and a half years, she lost 150 lbs., and had her daughter. She also started a fitness blog and Instagram, and even won a bodybuilding competition.
“I look back on all the stuff I did and say, ‘Did I really do that?’ ” she admits. “As someone with such severe anxiety, to go out and do that, I know that I’ve progressed, not only physically but mentally as well.”

Morgan Root: Lost 128 Lbs.
Transitioning out of the military and into life as a stay-at-home mom, took a toll on Morgan Root's body. She went from 145 lbs. to 255 lbs. in just two years.
"I felt ashamed of how I had changed from a veteran Army soldier into someone who I wasn’t proud to be,” Root, 35, tells PEOPLE for the 2018 Half Their Size issue. "When I transitioned out of the military, I was pregnant with my son, and that loss of structure meant I was eating what I wanted to with no regard, and being pregnant I just found myself eating a lot more than usual."
When her son was six months-old, the Richmond, Georgia resident became pregnant with her daughter and gained even more weight.
"I didn’t want to be in pictures with my kids. I had trouble catching my breath; I had hip issues and a lot of body aches. I couldn’t walk like I should be able to walk."
"I decided to join Nutrisystem because it gave me the structure I needed and fit with my busy schedule as a mom," explains the graduate student, who now weighs 127 lbs.
She also joined a gym.
"My kids used to be an excuse for why I couldn’t work out or make myself a priority. That excuse is now my motivation for everything I do."

Jermaine Gause: Lost 303 Lbs. (and Counting!)
Weighing in at 639 lbs., Gause was terrified of dying.
“I’m not ready to leave this planet,” he said during an appearance on The Doctors in Oct. 2016. “And I know the way I am now, I probably don’t have much time.”
Gause was ready to make a change, and he immediately joined Live in Fitness, a residential weight loss community. There, he completely revamped his diet plan to focus on lean proteins and vegetables, and started exercising. In just over a year, he's lost 303 lbs.
“Since losing this weight, I’m like a new person,” Gause said during a return visit to The Doctors. “Every day I wake up and I can move.”

Samantha Call: Lost 125 Lbs.
In 2008, Samantha Call lost her father to heart disease. He was 48 years-old and struggled with obsesity.
Call, who was 265 lbs. at the time, also struggled with her weight.
"I’ll never forget sitting with my [12-year-old] brother after my dad had passed, when he told me ‘Samantha, I don’t want you to die like daddy did,’ Call, now 33, told PEOPLE. "That broke my heart but gave me the drive that I needed to start my journey.”
In early 2009, Call found success with Atkins. And after a year and a half got down to 132 lbs. Call has maintained her weight loss for about seven years.
Now, she cooks healthy meals at home vegetables home with her fiancé and devotes an hour before work to exercise. Says the Callis, Maine resident: "It’s part of my daily routine."

Jason Cohen: Lost 125 Lbs.
Jason Cohen always struggled with his weight. At his highest, he hit nearly 300 lbs.
"My entire life I always thought I would be big," said Cohen, 33, who ran, cycled, forged a weight-loss competition with a friend, and adopted a plant-based diet to help him slim down.
A big motivator to help him acheive and maintain his 125 lbs. weight loss is a private Facebook support group dubbed the "Missing Chins Run Club."
“When I see other members post a 7-mile run in the Facebook group, I don’t have any excuses,” said the Lafayette, Louisana resident. "Time to lace up and get out there."
16 of 59
Jessica Beniquez: Lost 175 Lbs.
At over 320 lbs., Jessica Beniquez lived a sendetary lifestyle. "I laid in bed watching series after series on Netflix. All I did was eat, go to work and watch my shows," the 21-year-old tells PEOPLE.
Tired of feeling "lazy," she finally committed to her losing weight in February 2016. She ordered Herbalife shakes and "never looked back."
Sticking to a "strict" 1200-1500 calorie-per-day diet and joining a gym helped her lose 175 lbs.
Now, 145 lbs., Beniquez works at the front desk at her gym and hopes to become a certified trainer. She also continues to share her weight loss journey on Instagram.
"I never expected to be where I am today. I was shy, but now I have so much more confidence, I have so much more energy,” says the Spring Hill, Florida resident. “Before it took me 20 minutes to walk a mile and now I can run 5 miles in under 50 minutes…It’s crazy the things I can do now that I couldn’t do before."
17 of 59
Laura Hyman: Lost 103 Lbs.
Laura Hyman's weight reached 264 lbs. because she was used to "talking care of everyone else but myself," the now 54-year-old grandmother tells PEOPLE.
Along with her husband Myron, Hyman has now lost over 100 lbs. using the Isagenix weight loss program, which the retired Indio, California couple started in 2015.
“[Isagenix] gave us a time schedule for our meals and snacks,” says Hyman, who now weighs 161 lbs. and eats five times a day: two shakes, two snacks and one full meal. “This system taught us that not only the food we are eating counts but the timing of when we are eating is so important.” Now after dinner, Hyman says, “the kitchen is closed.”
The couple also started a 16-week body transformation program at the beginning of their weight loss journeys. Hyman, who works out with a trainer 3 to 4 times per week, is now a finalist in her sixth Isabody Challenge.
"I fuel my body and don’t eat for emotional reasons,” she says. “I feel better than I did in my 20s."
18 of 59
Jovana Borojevic: Lost 139 Lbs.
Although she was happy and confident in her body, Jovana Borojevic was shocked when she finally stepped on a scale.
“I never in my life imagined that I would see a ‘3’ in front of my weight,” Borojevic, who hit 304 lbs. and had developed fatty liver disease from her fast food-heavy diet, all while dealing with Polycystic ovary syndrome, or PCOS, tells PEOPLE. “From this day forward, something clicked in me and I changed my life around cold turkey.”
The digital marketing strategist, now 24, immediately cut out starchy carbs, refined foods, sugar and most packaged food. In a month she dropped almost 20 lbs., and started hitting the gym four to five times a week for weight training and cardio workouts.
Now a year and a half into her weight loss journey, Borojevic is down to 165 lbs., with a goal weight of about 150 lbs.
“It is SO IMPORTANT to focus on non-scale victories like how your clothes fit, how you feel, how many health issues you’ve reversed and saved yourself from and how happy you are!” she says.

Allie Ruby: Lost 98 Lbs.
Allie Ruby was determined to lose weight — and get her long-desired six-pack — after her poor college eating habits left her at 225 lbs. But 98 lbs. later, she still wasn't happy.
“I always thought that I would love to have a six-pack, and when I got there last year, it wasn’t all the fireworks I thought it would be. I thought that would be a huge high, but it wasn’t,” Ruby, 28, tells PEOPLE.
She started weightlifting, which kept her in amazing shape but pushed her weight up again, this time with muscle instead of fat. Seeing the numbers creep back up the scale caused self-doubt.
“If you have ever lost a substantial amount of weight then gained some back you probably have an idea of that devastating feeling of going backwards — I think those feelings were more painful at that time than when I was overweight,” Ruby wrote on Instagram, adding that it’s been helpful to practice mindfulness at this point in her journey. “I had to remember that a transformation is far deeper than physical.”
Now she's switched from weightlifting to powerlifting, which requires extra weight, and is much happier.
“It’s so different, because no one cares about your image. It’s all about how strong you are,” Ruby tells PEOPLE. “I love it.”
20 of 59
Janice “JJ” Jobity: Lost 120 Lbs.
Jobity was always fit growing up, but when she was mistreated in a relationship, she turned to food to cope.
“I stopped caring for myself as much as I should have,” the Toronto-based finance project analyst, 36, told PEOPLE. “I was depressed. I just kind of tuned out of the world, and food became my everything."
By 2015, Jobity had hit her highest weight of 260 lbs. and started feeling excruciating stomach pain.
“When I went to my doctor they explained I had a stomach ulcer, and that all those years of soda had damaged my stomach,” she said.
Jobity decided to get healthy — mentally and physically. She started taking boot camp classes and sought counseling to deal with her emotional issues.
What She Eats Now: Jobity cut out fried food and soda and eats a diet focused on fruits, vegetables and lean protein. “I love salad and chicken,” she said. “Salad and chicken are my everything!”
Her Workouts Now: Jobity works out six days a week.
Her Best Weight Loss Tip: “You have to fix what’s going on inside before you can fix the outside. The mind is a powerful thing through the weight loss journey, more than anything else. A lot of weight loss is mental.”

Naomi Teeter: Lost 150 Lbs.
Teeter had struggled with her weight her whole life, and found herself weighing over 300 lbs. by the time she was 26. She ignored her mounting health problems — painful water retention in both her knees, eczema breakouts and nightly bouts of acid reflux — until a doctor's visit that inspired her to make a change.
She began keeping a food diary and joined a gym. Teeter, now 34, soon was physically capable of doing things she never thought possible, like running multiple half and full marathons, climbing a mountain and even sky diving. But it wasn't until she ran a naked 5k that she learned to truly embrace her body.
“It’s not often in your life that large groups of people openly accept you and cheer for you despite what your body looks like or your physical ability,” she told PEOPLE.
What She Eats Now: Teeter made healthy swaps for junk food and keeps track of her macronutrient intake.
Her Workouts Now: The Spokane, Washington-based health and weight loss strategy coach stays active with running, hiking and gym sessions.

Tara Kavanagh: Lost 145 Lbs.
The 5’7″ self-employed mom-of-three from Rapid City, South Dakota, 35, was already over 200 lbs. when she started having children, but her pregnancy weight brought her up to 304 lbs. After having her second child, she knew she wanted to make a change.
“I wanted to be an active mother and be able to play with my kids," she told PEOPLE. "I also wanted to live my life, not just exist. I wanted to experience new things and felt my size was holding me back.”
Kavanagh decided she did not want to undergo weight loss surgery after seeing relatives who ended up gaining their weight back. Instead, she focused on finding workouts she actually enjoyed and tracking what she ate.

Helen Costa-Giles: Lost 90 Lbs.
For years, Helen Costa-Giles had no real motivation to lose some of her 220-lb. body weight, despite concerns from her doctor. But in 2014, her yearly checkup took a somber turn when the mom of two learned that she was on track to develop chronic health problems because of her size.
“My numbers were really off the charts and it scared the life out of me,” Costa-Giles, 38, tells PEOPLE. “That was exactly my turning point.”
Determined, she immediately threw out all processed and preservative-filled foods, and started eating a clean diet. In just six months, with no exercise, she dropped close to 90 lbs. Costa-Giles then added weightlifting to her days, and fell in love.
“My body reacted very quickly to weightlifting, and I started to lean out,” she says. “The scale wasn’t making huge differences, but the inches were changing. I kind of got obsessed because for the first time in my life, my body was actually doing what I asked it to do.”
Costa-Giles now runs free exercise classes in her hometown of San Antonio at 4 a.m., four days a week, all while maintaining her full-time job in the automotive industry.
“I have two kids and a full-time job,” she says. “I know many people don’t start their fitness journeys because they have too many excuses. I like to share my story because it’s so relatable.”

Dustin LaJaunie: Lost 150 Lbs.
Dustin LaJaunie has come along way from the 425 lbs. he weighed five years ago.
Now, he's lost 150 lbs. and counting with the help of his younger brother Josh LaJaunie, who started the private Facebook support group called "Missing Chins Run Club."
The group is a safe place for people to share their stories and struggles and to motivate one another to lose the weight.
Eating plan-based and running alongside his brother, Dustin compares the Missing Chins to the trips he and his brother used to take when going hunting. “But instead of gathering to go take life, we’re coming together to gain life."
25 of 59
Marie Byrne: Lost 70 Lbs.
The Gloucester, U.K.-based nursery manager, 42, was a longtime emotional eater who found herself reaching a high weight of 223 lbs. at only 5'3″.
“My blood pressure was through the roof,” she told PEOPLE. “The doctor said that I was a heart attack or stroke waiting to happen. My mum had a stroke very young, and it scared us as a family. I didn’t want to put my family through the same thing, so knew I had to do something.”
Byrne credits doing at-home Jillian Michaels workouts and decreasing her portion sizes with helping her drop 70 lbs. She also says having a partner with Parkinson's disease inspired her to get her health on track.
"When we first got together he was going to Pilates and would walk his dog three times a day," she said. "He was way more active than me. What excuse did I have not to exercise when he didn’t make any excuses?”

Her Workouts Now: She continues to do Jillian Michaels workouts every morning at 5 a.m. before starting her day.

Brittany Greenslit: Lost 109 Lbs.
The office worker weighed 236 lbs. by the time she was pregnant with her first child due to poor eating habits and a lack of physical activity.
After complications from her c-section left her depressed, Greenslit, now 27, started walking and doing Pilates and yoga to help lift her mood. As soon as she was well enough, she began doing Jillian Michaels’ workout DVDs.

Alicia Steele: Dropped from Size 10 to 2

Megan McGee: Lost 70 Lbs.
McGee began gaining weight when she got into an unhealthy relationship and stopped spending time with friends or going to the gym. After getting out of the relationship, she decided it was time to make a change — especially since she worked in the health profession.
“As a nurse, I wanted to be the healthiest version of myself that I could be,” she told PEOPLE. “I didn’t want to be a walking contradiction to my patients, promoting healthy living but not being healthy myself.”
The Middlesex, England-based nurse, 26, decided to join Slimming World to take control of her health.
What She Eats Now: McGee went from skipping meals and snacking throughout the day to sticking to set meal times. “I eat a lot of the same meals as before, but I’ve learned how to make them differently so they’re healthier, like using lean meat and making sauces from scratch."
Her Workouts Now: McGee loves group exercise classes and also regularly meets with a personal trainer.
Her Best Weight Loss Tip: Don't be afraid to make a change. "There is nothing to lose and so much life to gain.”

“I hit the ground running,” she told PEOPLE. “I used the app My Fitness Pal on my phone, and I plugged in how much weight I wanted to lose and how fast I wanted to lose it. They gave me a calorie target, and I followed it. I literally had to reteach myself to cook.”

The mom-of-four, 39, fell into unhealthy eating habits after having kids.
“I made dinner for the boys and ate what they ate," she told PEOPLE. "I did not take the time to prepare healthy dinners, as it’s very hard when you’re a full-time employee and mother of four.”
When one of her sons told her she looked "really fat," she decided she needed to start making health a priority. On nights she has a sitter, McDonald hits the gym, and on other nights she does workouts at home once her kids are asleep.

In December 2015, Cines read about a Bodybuilding.com challenge and decided to take part in it. She started working out three times a day and saw real changes in her body for the first time.

Powers began logging her food intake using the Lose It! app, and says it helped keep her accountable. Now she eats a lot of lean meats and vegetables, and works out three times a week.
“I like that my kids are used to hearing ‘yes’ a lot more,” said Powers. “Before, I could never take them to the park and run around with them and be the mom that I wanted to be. Now there’s no limitations.”

“It was in front of my children,” she told PEOPLE. “It was horrible. I went home and cried a lot, but I realized kids learn from what you do, not what you say — and that’s what kept me pushing.”
Pullen decided to try bodybuilding, and turned to Arnold Schwarzenegger for her inspiration.
“I started watching some of his motivational videos and using his workout videos," she said. "It really helped me because there were so many times that I thought, I can’t do this, it’s too hard.”

Now she does cardio five days a week and strength training two to three days a week, and even teaches fitness classes as a certified personal trainer.
