It's a soft and squishy, and about the size of a small bowling ball. I thought the price was good, and it qualifies for free shipping (as long as total order is over $25). I did the third segment of Core Max this morning and it worked perfectly!
These balls are just what I wanted. They are firm and bounce (I wanted to be able to play med ball with my kids). I have some squishy smaller ones too, and those are also nice but they don't bounce.
I bought my med ball online at www.karatedepot.com They are having a sale on shipping ($2.95) and I dont have a car so this was great. I got the 9 lb black med ball.
I got the same one Elaine did and I love it! Walmart is a good resource for exercise equipment from dumbells, barbells, stability balls, med ball, step, etc. Cheap too!!
