The Bender Ball works......But
The ball itself works.It gives you an excellent abdominal workout.
The first time I used it I thought "I don't feel a thing" but then the next day I could barely sit up. Take it easy at first. The ball is pretty poor quality...it needs to be constantly blown up (gets pretty irritating). Now for the "but"...
the company has been running a scam where the customer is signed up for a continuity plan without their knowledge, luckily I found out before I ordered.Check it out and be informed...http://www.associatedcontent.com/article/881313/are_you_the_next_victim_of_the_bender.html?cat=50
