This is the best program for seniors like me. I will be 71 next month, and I work full time in a grocery store, so I’m pretty active. But I find that systematically going through the exercises, I am gaining muscle mass, balance and strength. I feel like Deron really understands seniors and knows how to lead us through the program, no matter what medical problems we may have! I recommend this program to all seniors who want to get themselves back into a good life!
