Exercise Ball Crunch: Exercise Overview
The exercise ball crunch is a dynamic core exercise designed to target the rectus abdominis, with secondary engagement of the obliques and hip flexors. Performed on a stability ball, this movement increases the range of motion compared to traditional floor crunches, enhancing core activation and challenging balance and stability.

Ideal for building abdominal strength and definition, the exercise ball crunch is a versatile addition to core-focused workouts, ab routines, or full-body training programs. Its use of a stability ball makes it suitable for lifters and fitness enthusiasts of all levels, with modifications available to adjust intensity (Schoenfeld, 2010).
How to Perform the Exercise Ball Crunch
- Sit on a stability ball with your feet flat on the floor, hip-width apart.
- Walk your feet forward, allowing the ball to roll under your lower back until your torso is slightly reclined—this is your starting position.
- Cross your arms over your chest or place your hands lightly behind your head (avoid pulling on your neck).
- Engage your core and curl your upper body upward, lifting your shoulder blades off the ball while squeezing your abs.
- Pause briefly at the top for maximum contraction, then slowly lower back to the starting position, maintaining control.
- Repeat for the desired number of repetitions.
Tips for Optimal Performance
- Maintain Stability: Keep your feet flat and firmly planted to stabilize the ball, ensuring balance and preventing rolling during the movement (McGill, 2010).
- Control the Movement: Perform the crunch and descent slowly to maximize time under tension and avoid using momentum, enhancing core engagement (Schoenfeld, 2016).
- Avoid Neck Strain: Lift with your abs, not your neck, and keep your head in a neutral position to prevent discomfort or pulling with your hands (Wirth et al., 2016).
- Breathe Properly: Exhale as you curl upward and inhale as you lower back down to support core stability and muscle oxygenation.
- Engage Your Core: Brace your abs throughout the movement to protect your lower back and maximize abdominal activation.
- Adjust for Comfort: Start with a smaller range of motion or fewer reps (e.g., 10–15 for hypertrophy) if new to the exercise, progressing as your core strength improves.
