Setup
- Grip the pull-up bar with an overhand (pronated) grip, slightly wider than shoulder-width.
- Hang with arms fully extended and shoulders 'packed' by pulling your shoulder blades down and back.
- Start in a dead hang with your legs straight and core pre-engaged to prevent swinging.
How to do it
- Exhale as you pull your knees toward your chest, then continue curling your pelvis upward until your knees touch your elbows or triceps.
- Pause for a split second at the top, squeezing your abdominals hard to maintain the contraction.
- Inhale as you slowly lower your legs back to the starting position with a controlled 2-3 second tempo.
- Stop the movement just before your legs go behind your torso to prevent momentum for the next rep.
Form checklist
- Ensure your knees actually touch your elbows to guarantee full abdominal shortening.
- Avoid using momentum or swinging the legs to 'cheat' the weight up.
- Keep your arms straight throughout the movement; do not turn it into a pull-up.
- Focus on curling your hips toward your ribs rather than just lifting your thighs.
Pro tips
- Think about 'pulling' the bar down toward your knees to engage your lats, which creates a more stable base for your core to pull against.
- To maximize muscle fiber recruitment, focus on the 'tuck' at the very top of the movement where the pelvis tilts posteriorly.
Make it harder
- Transition to 'Toes to Bar' by keeping your legs completely straight throughout the entire range of motion.
- Add a 3-second isometric hold at the top of each rep when knees are in contact with elbows.
