- Position yourself on a vertical bench with your back flat against the back support and your hands firmly gripping the handles.
- Pull both knees up into your chest, and with control, lower them back down to the starting position.
- From here, fully extend both legs and lift them up until you've reached parallel (or as far as you can go). Lower your legs back down to the starting position.
- This completes one rep.
