BOSU® Sport 21.65" Balance Trainer


great trainer

 from suwanee, GA– Verified Buyer

Actually used this for my dog's physical therapy so we could do her exercises at home after a sports injury. Great construction, sturdy, did what I needed it to!

Excellent value for money

 from Fremont, CA– Verified Buyer

I worked with the Bosu Professional edition with my physio and I believe this is meant for less strenuous/personal use. I am very satisfied with the product so far as I don't see major difference between the two. The only thing missing the solid base at the bottom that would perhaps be needed if it is going to be used a large number of people at the gym.

Works for me

 from Ashville, NY– Verified Buyer

I needed something to assist me in increasing my sense of balance. This is the perfect solution. Easy to clean and doesn't take a lot of space. Try to stand and watch TV for at least 3-4 minutes twice per day. Can now do it for almost 8 minutes.
