Setup
- Stand with your feet slightly wider than shoulder-width apart and a slight bend in your knees.
- Bring your hands up to chin height in a 'guard' position with your fists clenched and palms facing inward.
- Engage your core and keep your chest lifted with your gaze forward.
How to do it
- Shift your weight to your right leg while simultaneously kicking your left heel toward your glute for a hamstring curl.
- As you curl the leg, punch your right arm straight up toward the ceiling, rotating your palm to face forward at the top.
- Exhale forcefully on the punch and curl, then inhale as you return both the foot and hand to the starting position.
- Immediately repeat the movement on the opposite side, alternating legs and arms in a rhythmic, continuous flow.
Form checklist
- Keep your core braced to maintain balance and prevent your lower back from arching.
- Ensure the curling heel travels directly toward the glute rather than flaring out to the side.
- Fully extend the punching arm without snapping or locking the elbow joint.
- Maintain a steady, upright posture; avoid leaning excessively to the side as you shift weight.
Pro tips
- Focus on a hard squeeze of the hamstring at the top of the curl to maximize posterior chain engagement.
- Drive the punch from your shoulder and back muscles, using the slight torso rotation to engage your obliques.
Make it harder
- Increase the tempo to a rapid pace to transform the exercise into a high-intensity cardio movement.
- Hold light dumbbells or wear wrist and ankle weights to add resistance to the pushing and curling phases.
