Bought a stability/exercise ball....

Never knew how much you can do with them. My gym has a few, I never used them though. Just googled up about 10 exercises I can do right at home with it.

Anybody else use them?

I use them for abs and different variations of push ups after lifting. Gotta get a new one though cause my dog popped it a couple days ago

Push up position. Put your feet on the ball and bring your knees to your chest. Great for abs
