Weighted Leg Extension Crunch
The Weighted Leg Extension Crunch targets your core and lower body muscles effectively.
- Begin seated on a bench with your back straight and feet flat on the ground.
- Hold a weight plate against your chest.
- Extend one leg out in front of you while simultaneously crunching your torso forward.
- Return to the starting position and repeat with the opposite leg.
How to perform the Weighted Leg Extension Crunch
- Set up. Set up in a stable, balanced starting position appropriate for the Weighted Leg Extension Crunch using your stability ball.
- Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your glutes.
- 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 glutes 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.
