Crunches on a stability ball are an excellent way to work on your core and balance at the same time. Pro tip: To make this exercise more challenging, position the ball lower on your back.

Step By Step Instructions

Step 1

With your knees bent, lean back onto a stability ball. Position yourself on the ball so that your middle back is comfortable, your knees are bent at a 90-degree angle, and your hands are behind your head. Keep your feet on the ground.

 Step 2

Raise your head and shoulders forward. As you complete each crunch, engage your core by breathing rhythmically and pulling your stomach to your spine.

For the progression, slightly rotate to alternating sides as you execute each crunch. Start with 5 repetitions, then build to 10. Once you can comfortably complete 10, you are ready to try the progression.
