I found myself in a situation where I could only train in the gym at work and it didn't have a squat rack. It also allows me to train at home when I need to with largely the same equipment. This is a mash up of different things designed to be quick and use minimal equipment. It does utilise alot of rest pause training. When you can hit 10 reps on the on all sets of the normal exercises or hit 10 reps on the first set of the rest pause exercises, increase the weight.
