Is a ball's weight limitation measured by my body weight alone?
No, there's more to it than that. Weight limits are measured in two ways: static and dynamic. Think of static weight as you just sitting on your Sissel ball. Now imagine bouncing up and down or lifting heavy weights while sitting on the ball - that's dynamic weight. For your safety and to preserve the life of your ball, do not exceed the ball's weight limitation.

If you plan to use your ball for cardio (bouncing) or for strength exercises that require additional weight like dumbbells or barbells, select a ball that is especially designed for these purposes. Click here to find out more about recommended activities for each of our balls.
