Setup
- Adjust the suspension straps so the handles hang at approximately waist height.
- Stand facing away from the anchor point and grasp the handles with a firm overhand grip.
- Lean forward into a plank position with arms extended directly under your shoulders and feet hip-width apart.
- Engage your core and glutes to create a straight line from your head to your heels.
How to do it
- Slowly push the handles forward and upward, extending your arms past your head while keeping your body perfectly rigid.
- Inhale deeply as you extend, reaching as far as possible without allowing your lower back to arch or your hips to sag.
- Hold the 'extended' peak tension position for 1-2 seconds while maintaining full body tension.
- Exhale and use your lats and abdominals to pull the handles back to the starting position under your shoulders.
Form checklist
- Maintain a posterior pelvic tilt (tuck your tailbone) to protect the lower back.
- Keep your elbows straight but not locked out throughout the entire range of motion.
- Ensure your head stays in a neutral position, looking slightly down and forward.
- Do not allow the straps to rub against your shoulders or upper arms.
Pro tips
- Focus on 'knitting' your ribs toward your pelvis to maximize tension in the deep core and prevent rib flare.
- Squeeze the handles as hard as possible to increase irradiation and stabilize the shoulder girdle through the pectorals and deltoids.
Make it harder
- Move your feet further back toward the anchor point to increase the horizontal load and difficulty.
- Add a 'saw' motion at the point of full extension, moving the arms forward and back 2-3 inches before returning to center.
