This exercise can be done in the sissy squat machine as shown in the pictures above,
or without machines by holding a vertical bar with one arm for support.
Stand in the machine with your legs completely against the pads, your arms across
your chest and your body over your ankles.
Slowly lower your body into a sitting position.
Using the heels of your feet, push your body back up to the starting position and
contract your thighs.
Tips
Focus on proper form, as this exercise is excellent as preparation for squats using
added weights.
