I'm a mom of 4 who's been an athlete my whole life. At 42 I found myself tired and exhausted and about to have to give up distance running due to discomfort in my knees and hips. I started using the 3 step system and noticed difference right away. Some were subtle and some were pretty noticeable. Energy, better sleep and by day 3 my knees and hips weren't hurting on an 11 mile run. I personally didn't need to lose weight. What I love is this isn't a diet system. It's a total healthy lifestyle system for anyone and everyone no matter their goal.
