All five StayFit blocks in one place - shoulders, hips, lower back, knees and ankles - plus the order to run them in.

About thirty weeks if you run the whole thing, and it is built to be run in pieces. Most people do two or three blocks and keep the maintenance sessions going.

Bodyweight only. A wall, a step and some floor space covers all five.

Cheaper than buying the blocks one at a time. If you only want one area, buy that block instead - the training in it is the same.
