The Gravity Ball makes dynamic movements possible with its strap design that secures the weight to your hand (or foot), which frees up your attention to focus on the movement and not on gripping the weight.

The Gravity Ball will challenge your nervous system by forcing you to stabilize the spherical weight in space while you’re exercising.

The Gravity Ball’s versatility means that you can build strength, increase mobility and flexibility, improve symmetry and enhance balance all in a single device.

The Gravity Ball’s compact, portable design increases the chances that you’ll develop a regular habit of doing daily resistance exercise which will increase your strength, flexibility and mobility while improving your mood and energy levels as well as many other health benefits.


A Gravity Ball™ can be used just about anywhere, including:

  • In the park

  • At the gym

  • In the office

  • At home

  • While travelling

A Gravity Ball™ replicates exercises traditionally done using five of the most common types of equipment, including:

  • Kettlebell

  • Dumbbell

  • Yoga Stretch Strap

Getting Started with Gravity Ball™

We often get asked which weight of Gravity Ball should I use? All Gravity Balls have the same circumference of 57 cm (22.5 inches) which makes them about the size of a volleyball. There are three weights to choose from, each differentiated by color.

In general, we recommend the blue Gravity Ball™ most often. It's ideal for most people who are new to exercise. The heavier weights (orange and black) in general are designed for those who are more experienced with exercise.

The Story of the Gravity Ball™

Dr. Mark Chavez designed the Gravity Ball™ at a point in his life when he had lost his own health. He had gained 60 lbs working long hours in the emergency room. His father had recently undergone a devastating nerve surgery causing him to lose his grip strength. Searching for an all-in-one solution to resistance exercise and for his father to be able to exercise again, a concept that was effective, challenging, compact, and versatile was born — the Gravity Ball.



Every Gravity Ball™ is made from damage resistant synthetic rubber.

Made of high tension nylon and designed to fit
the average hand size for both men and women.

Each loop strap is 6.25 inches or 15.8 cm in length

Each removable strap is 10 inches or 25.4 cm in length

Our high capacity carabiner clips are rated to the strength of 800 lbs.

Circumference: 57 cm (22.5 inches). About the size of a volleyball.
