Find yourself a squat rack and get ready to pile some solid work into your lower half. This workout will strengthen your quads, hamstrings, glutes, abs and mental strength. Because your aim is to smash through each of the 5 rounds of 20 reps, you can only rest for the prescribed 60 seconds after each round.
