But that doesn't mean I'm going to give it less than 5 stars just because I didn't read the description as carefully as I should have.Yes, the ball is only about twice as big as the size of a baseball. But it's still very good for the exercises I am doing. As people have said, it can get slippery but I counter that by wearing a glove so I can maintaing a good grip on it. Other than that, I really enjoy the size because it allows me to work on balance and speed as well as strength (maintaining high intensity). Additionally, it opens up a lot of other workout options since some exercises are just not efficient with huge medicine balls. I've tried bigger sized medicine balls and those are good too, but either size gets the job done, really. Don't forget to pump it up just a little bit when you get it since it will be completely deflated.It is a good product but it has a lot of negative reviews simply because people thought they were going to get a standard size ball.
