Have you seen Lindsay Lohan's most recent mugshot? What freaked me out even more than the fact that she'd been arrested yet again was that the article mentioned her age – she's 26-years-old! Not 36 or even 46. Just 26! Even if we don't party as hard as Miss Lohan, this much is certain: We will age. However, there's plenty we can do to distance ourselves from Father Time. Here are six tips and the celebs who swear by them to look amazing.

1. Don't Make Your Fitness Dependent on One Machine/Person

Who gets it right: Sandra Bullock, 48
It's hard to believe Demolition Man was 20 years ago, since Sandra Bullock looks almost exactly the same at 48 as she did then. She didn't achieve the body she has now by doing the same tired routine every day! Bullock likes to mix up her workouts, doing everything from Pilates to kickboxing. Our bodies adapt to a regimen within six to eight weeks, so if you don’t mix up your routine, you will plateau.

2. Graze, Don't Gorge

Who gets it right: Halle Berry, 46
Halle Berry is ageless! As she nears 50, Berry manages to look younger and younger. She also happens to be diabetic, so she knows how important it is to eat many small meals and snacks throughout the day. By grazing as the day goes on, you have fewer energy swings and keep your appetite in check.

3. Don't Skip Meals

Who gets it right: Jeff Goldblum, 60
At 60, Jeff Goldblum looks exactly as ripped and lean as he did in 1986's The Fly. It could be because he makes an effort to never skip meals. Not only does skipping meals wreak havoc on your metabolism and blood sugar, but it also reduces energy, decreases bone density and lowers our immune response, which are all critical issues whether you're 20 or 70.

4. Don't Over-Exercise

Who gets it right: Sharon Stone, 54
One of the most common mistakes I see people making is over-exercising. Working out too hard or too much will lead to a sidelining injury. The key is – as it is with almost everything – moderation. Stay active all day instead of trying to get your physical activity in for the day in an hour at the gym. Sharon Stone looks as incredible as ever and only works out as much as she has to, staying active throughout her day by doing things like parking far from the entrance, etc.

5. Listen to Your Body

Who gets it right: Jane Seymour, 61
While many of us were taught to "play through the pain," it's not great advice. If you feel joint or muscle pain that lasts more than a few days or if one side of your body hurts more than the other, it's time to rest and/or see a doctor. Jane Seymour has said in interviews that her approach to fitness is cautious.

6. Experiment with Stress-Reducing Techniques

Who gets it right: Vanessa Williams, 49
You can't ignore science: Studies show that stress accelerates aging. How can you relax? My longtime client and friend Vanessa Williams has said that counting her blessings works for her. By focusing on the positive in her life, Williams says it's a lot easier not to be stressed. Many of my clients find relaxation and peace with yoga, while others embrace meditation. For me, laughing with my wife over dinner or a hilarious TV show really releases tension.
