Lateral Style Crunch (On Stability Ball): How to Do It & Muscles Worked
The crunch on a stability ball is an abdominal exercise that targets the abs while also engaging the hip flexors. The use of a stability ball increases the challenge to balance and core stability compared to a regular floor crunch.
How to do the lateral style crunch (on stability ball)
- Step 1: Sit on the stability ball with your feet flat on the ground and your knees bent at a 90-degree angle.
- Step 2: Lie back on the ball until your lower back is supported and your upper body is parallel to the floor.
- Step 3: Place your hands behind your head or across your chest. Focus on lateral movement.
- Step 4: Engage your abs and lift your upper body towards your knees, curling your torso forward.
- Step 5: Pause for a moment at the top of the movement, then slowly lower your upper body back down to the starting position.
- Step 6: Repeat for the desired number of repetitions.
Sets, reps and programming
| Goal | Sets | Reps | Rest | Effort |
|---|---|---|---|---|
| Strength | 3–5 | 3–6 | 3–5 min | 1–3 reps in reserve |
| Muscle growth | 3–4 | 6–12 | 2–3 min | 1–2 reps in reserve |
| Muscular endurance | 2–3 | 12–20 | 1–2 min | 1–3 reps in reserve |
Ranges follow the ACSM position stand on progression in resistance training. Muscle grows across a wide range of loads when sets end close to failure (Schoenfeld et al., 2017), longer rests between heavy sets support strength and size (Schoenfeld et al., 2016), and stopping a rep or two short of failure works about as well as training to failure (Grgic et al., 2022). Estimate your working weights with the strength calculators.
