If more people picked heavy crap up, and then put it down, we'd have a healthier society. Instead we have all this selectorized equipment for isolating each muscle group. Guess what!! Thats not how the body moves. The body moves in a series of contractions of multiple major muscle groups and smaller, stabilizing muscle groups.
Seriously go out and lift heavy crap up, put it down, and repeat. That is your exercise prescription.
