Exercise Ball Frog Crunch
Perform the Exercise Ball Frog Crunch by lying on your back on an exercise ball with your feet flat on the floor. Position your knees bent and feet together, creating a frog-like stance.
- Engage your core and lift your upper body towards your knees.
- Hold the position briefly, then lower your back down to the ball.
- Repeat for the desired number of repetitions.
How to perform the Exercise Ball Frog Crunch
- Set up. Set up in a stable, balanced starting position appropriate for the Exercise Ball Frog 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 quadriceps.
- 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 quadriceps 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.
