Squats

The primary muscles worked during this exercise are the quadriceps, hamstrings, glutes and lower back.

Adjust the pressing arms and the squat attachment for the desired range of motion, normally so that your legs are parallel with the ground. If you go too far down you will put greater stress on your lower back.
Position yourself under the squat attachment with your legs shoulder wide.

Keep your head slightly up and back arched. Drive the weight up with an explosive but controlled motion. Don't lock your knees completely at the top. Lower the weight slowly and repeat.
