How to Perform
Anchor the suspension trainer overhead and grasp the handles with a neutral grip (palms facing each other). Lean back with arms fully extended and feet positioned to establish the desired resistance level.
- Brace your core and glutes to maintain a rigid straight-line plank.
- Keep your elbows lifted high and fixed in space throughout the rep.
- Curl your hands toward your temples by flexing the elbows.
- Squeeze the biceps and forearms hard at the top of the movement.
- Lower yourself back to the starting position with control.
