Select your weight. Lie on your side facing the weight stack. Place legs between roller pads so that the front pad is against your hip and the rear pad against the back of your thigh. Hold handhold with an overhand grip, arms streched. Rest head on pad.
Moving from the hips slowly extend both legs as far back as possible.
Hold briefly in this position and slowly return legs to starting position. Make sure that the weights do not touch down. Repeat until a full movement is no longer possible.

Important: Don't swing body and press legs back evenly from the hip.
