Seems like stressful times on the Ranch, eh?

Laura asked about injuries and how contestants deal with and prevent them. She is correct that contestants hit the treadmills hard while on the Ranch, but in the beginning there is not a lot of running. It is a lot of incline walking, which has less impact on the knees than jogging. Plus, contestants move around to lots equipment, so we are still doing cardio but using different muscle groups. Also, we would ice after every workout.

Katie would like to know what is the average number of calories the contestants try to burn each day and what is the average length of workouts. This answer can be two-fold (on the Ranch and off the Ranch), but I am only going to tell you what Jillian wanted me to do once I was home (before the finale). I was supposed to work out an hour and 30 minutes consecutively. After that workout, I would take a break to eat something and recover, then repeat. I was supposed to hit a burn of 4,000 calories a day while at home. Some days were easier than others! I would be in taking around 1,250 calories plus free greens.

If you have more questions let me know, and I will continue to do my best to answer.

On to this crazy episode! Biggest Loser has gone back to singles and there is definitely a feeling of relief that you feel as a contestant, because know you only have to look out for yourself. On the other hand, if you have watched The Biggest Loser you know that someone is coming back into the house the week it goes to singles — it is just a matter of figuring out who that someone will be!

I am sure the contestants did not think two would be coming back! It was awesome that Victoria was given a chance to finally be on the Ranch. I can’t even imagine going through the entire casting process, then meeting Allison, Bob and Jill briefly and then packing your bags. That would be a roller coaster of emotions! When it came down to Michael’s vote, I thought to myself, “Of course producers would put him last after his antics in the past.” When he said Victoria I was smiling so big my cheeks hurt!

Of course, nothing is ever that simple on the Ranch! Allison announced a step-up challenge for the contestants at home. Melissa‘s eyes widened and her focus became super clear: She wanted back and would stop at nothing to make it happen. I am sure this really upset the contestants. Just when they thought they got rid of the Red Team, they’re back! (Just a thought — I don’t really think this is a good move for her. I think she has better chance at winning at home than the grand prize. Do you agree?) She won the step-up challenge and got her place back on the Ranch. We’ll see if she can be steadier in her weight loss now that she doesn’t have her hubby to see-saw with any more! I am pretty sure a few of the contestants had a nightmare of a woman in red yelling, “I’m BACK!”

Also, today I will do 1,000 step ups for an added burst of cardio and I want you to do it with me! Make sure to post your times!

My MVP this week is Cherita, who spoke up for her daughter, Victoria, and allowed her the opportunity to return to the Ranch. Cherita pulled at the heartstrings of the contestants and gave her baby girl another chance. There is nothing like a mother’s love.

Lastly, I wanted to recognize Wayne, the fan who lost all that weight at home, for his major transformation. He was diligent and persevered with his weight-loss battle. I am happy that I will be able to meet him at the finale!

Keep your questions coming! –Tara Costa
