When my father started to have problems with his shoulder and knees over 10 years ago, I started thinking about a way to improve his physical therapy exercises.

The equipment that was available at the time did not seem efficient and versatile enough.

A friend constructed the first prototype using a pasta colander, a giant tennis ball and a bicycle pedal strap.

After the technology was patented for use in fitness, I began instructing Omniball classes at University of California Irvine. Originally, I thought it would just be a great therapy tool and help with core strength training, but it soon became much, much more.

It is the most versatile tool I have come across in my decades of fitness experience, working with all kinds of exercise equipment. Because the Omniball has no linear limitations and can be used on both hands and feet, its options for unique workouts, at all fitness levels, are endless.

I hope to see even more new faces training with the Omniball, from absolute beginners to professional athletes, and that everyone will find them as fun, challenging and inspiring as I do every time I roll them out.
