Gym Exercise Card
Equipment
The crunch on a BOSU ball enhances core stability and strength by engaging the rectus abdominis while also challenging balance. This variation of the traditional crunch increases the range of motion and activates stabilizing muscles, offering a more dynamic abdominal workout.
How to do it
- Start by sitting on the rounded side of the BOSU ball with feet flat on the floor and knees bent.
- Lean back slowly, keeping your core engaged, to rest your lower back on the ball.
- Cross your arms over your chest and perform a crunch by lifting your shoulders off the ball while exhaling.
- Pause at the top and then slowly lower back down to the starting position.
- Repeat for the desired number of repetitions, maintaining control throughout.
