Swiss ball crunch

A Swiss ball crunch is an exercise that uses a large inflatable ball to help target abdominal muscles. You sit or lie on the ball, which supports your back, and then lift your upper body towards your knees by engaging your abs. The ball provides extra support and a gentle stretch to your spine, helping you perform the movement with better form and reduced risk of strain. It effectively works the core muscles, improving strength and stability, and can be adjusted for different fitness levels by changing the difficulty or position.
