A great price for a great ball. My trainer liked it so much, she bought to use at the gym where she works. Unlike other medicine balls which are hard, this one is a bit "squishy" so you can grip it easily with your hands, between your knees for leg work, use if for push-ups, etc.
I have the 8 and 10 pound, purchased this and am very happy.These balls are soft - medium firm [cannot bounce] but are easy to grip and seem to be sturdy, do not burst after many accidental droppings.I think they are filled with sand but not to the point of being hard so there is a little give to the ball. Fun to work with playing catch with a partner, or working out and most important will not damage toes or hardwood floors if dropped.!
