What is your opinion on the insanity/p90x hybrid workout?

Not for the beginner: These workouts either singly or in combination are extreme. The diet is specific to each separate exercise program and the rest periods may not feel like rest. Do consult a physician and even a personal trainer at first.

Helpful . . .: . . . But must be performed after careful consideration and examination by your doctor. Additionally, the key in any exercise regime is committment and consistency. Personal trainers can also be helpful.

Reasonable option: But you just need to find a work out style that you will be able to commit to and consistently participate in. These home high intensity interval training work outs like P90X, Insanity or a hybrid are very efficient, but not necessarily for everyone.
