How to Do a Crunch with a Ball for Female Strength Training

Learn how to do a crunch with a ball from personal trainer Erin Sharoni in this Howcast workout video.


Hey, my name is Erin. I'm a former U.S. Junior Olympics certified swim coach and personal trainer. Fitness is my passion, so I cannot wait to share it with you guys.

We're going to do crunches on the ball. This is nice because it protects your lower back. Crunches on the floor are not ideal and I don't know recommend them. People kind of pull on their neck. The ball is nice and easy, it gives you some support.

Put the middle of your back on the ball. Walk your feet out. Place your hands lightly behind your head. Don't pull. Again, keep the neck elongated. Contract the core. When you come up, you're going to exhale.

Now, if you're a beginner, you want more of your upper back on the ball to make it easier. As you progress, you can move back a couple inches. Less of my back on the ball, the more difficult it is. If you keep your hands flat on your stomach, you should feel a nice contraction. There you have it, your basic strength workout for beginners.
