If you wish to follow a true strength program and want to follow the same 5% method used in the upper body workouts in this cycle, then you will want to order these optional STS Squat Rack routines. There are two ways to do the squat workouts when selecting this option. The first and best way is to use a squat rack with safety catches and a spotter. Two members of the cast are shown doing this in all four squat rack workouts. The other way to do these routines is to wear a weighted vest and use a short and lighter barbell like we normally use in the other segments of STS. This still may not be enough weight for some people to exactly follow the 5% method, but nevertheless it will give you an outstanding and challenging workout. The purpose of the weighted vest is to lessen the amount of weight you need on your barbell. This is beneficial because in an exercise like a squat (without a rack) you are limited by the weight you can safely lift overhead, not by the amount you can squat.
