Sit into the leg press machine, keep the working foot in regular position and slightly lower the "kickstand" leg for balance. Perform all on one side, then move straight into the other side. Engage your core, slowly drop into a squat, keeping your core engaged & push through your heels. Make sure not to fully lock out your legs.
