Physique 57 Exercise Ball

I ordered this ball because I broke the pump on my first physique 57 ball, so I figured I''d just get another ball/pump kit since I use it so much. Unfortunately this isn''t the "original" physique 57 playground ball. This ball is soft, actually it feels like velvet, and you inflate it with what looks like a straw. It doesn''t hold the amount of air that you need in order to do the videos and actually I worry that I''ll pop it cause it seems so flimsy. I would suggest that anyone who is new to the physique 57 videos, try and get the original ball/pump kit cause it''s thicker, and is a true playground ball.
