Alternate Straight Leg Raise (on bosu ball)
Perform the alternate straight leg raise on a bosu ball to engage your core and lower body muscles.
- Begin by lying on your back on the bosu ball with your arms at your sides.
- Lift one leg straight up while keeping the other leg extended on the ground.
- Lower the raised leg back down without touching the ground and repeat with the opposite leg.
- Maintain a stable core throughout the movement.
How to perform the Alternate Straight Leg Raise (on bosu ball)
- Set up. Set up in a stable, balanced starting position appropriate for the Alternate Straight Leg Raise (on bosu ball) using your bosu ball.
- 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.
