Crunch (On Stability Ball)
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.
Step-by-Step Form & Technique
- 1.Sit on the stability ball with your feet flat on the ground and your knees bent at a 90-degree angle.
- 2.Lie back on the ball until your lower back is supported and your upper body is parallel to the floor.
- 3.Place your hands behind your head or across your chest.
- 4.Engage your abs and lift your upper body towards your knees, curling your torso forward.
- 5.Pause for a moment at the top of the movement, then slowly lower your upper body back down to the starting position.
- 6.Repeat for the desired number of repetitions.
