A wonderful muscle building program

I really like this program and I really enjoy the automated instructions. I feel much better after each set. I’m 85 years old with a hip replacement and bad knee I can do most of the exercises . I would recommend this program to anyone wanting to increase your muscle strength.

These exercises and stretches have helped me tremendously with my back pain. Not a complete cure but a great improvement. Much less pain and better flexibility. Wait loss is a plus also. At 64 I can see abs.

Well thought out activity plan

Well thought out activity plan, which is supplemented with daily 'gentle' reminders.
Took the plan out for over a year and worked at it as scheduled. Didn't achieve my goals but felt that it was beneficial.
in the end, just thought it too expensive for an automated system.
