Lower the weight under control, until you reach slightly beyond a 90* angle at the working knee.
Lift the weight by pushing your heel into the pad hard, but don’t lock your knee at the top of the rep.
TIP: Think of this exercise as a machine version of LUNGES. You’ll get a slightly better range of motion versus a regular Leg Press due to only having one foot on the pad, and this will engage your glutes a heck of a lot more. Enjoy that burn.
