Corkscrew
The Corkscrew is a core exercise that targets the obliques and improves rotational strength.
- Lie on your back with your arms extended out to the sides.
- Lift your legs off the ground, keeping them straight and together.
- Rotate your legs to one side while keeping your shoulders flat on the ground.
- Return to the center and rotate to the opposite side.
How to perform the Corkscrew
- Set up. Set up in a stable, balanced starting position appropriate for the Corkscrew using your body weight.
- Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your abdominals.
- Reset. Reverse the movement under control and reset between repetitions, keeping your form crisp on every rep.
Coaching cues
- Move with intent — every rep should feel deliberate, not rushed.
- Drive force through your abdominals rather than momentum.
- Keep your breathing steady: exhale on the hard part, inhale on the reset.
Common mistakes
- Using too much weight and losing positional control.
- Cutting the range of motion short and missing the target muscle.
- Letting your spine round or hyperextend instead of staying neutral.
