Purpose: To build the muscles in the back (also works the biceps)
Execution: Take hold of the handles and plant your feet on the support platform. With your knees slightly bent, pull the handles into the lower abdomen, keeping your back as upright as possible, and your elbows close to your body. Try focusing on squeezing your shoulder blades together as you drive the handles into your abdomen. Let the weight pull you forward, stretching your lats before pulling in for another rep. Avoid moving the weight with momentum throughout the set.
