Training With Jay Cutler - Exercise 4 - Hammer Strength V Squat: The last exercise of the quads sessions and a great way to build the upper sweep of the quad muscles. Ideally a Hack Squat would be prefered. To begin the exercise, lower yourself down deep till your legs form a 90 degree angle or less before quickly exploding back up to the start position. Aim for 3-4 sets of 10-12 reps with 60 seconds rest in between sets. Jay Cutler - Mr Olympia & Nick Jones - World Bodybuilding Champion.
