Also Known As:
A regular ball.
A recent trend in fitness has been the emphasis on developing core strength. A popular way of doing this is to perform exercise movements while balancing yourself on a ball, which forces various muscles to help stabilize you. The Bender Ball is a tiny version of the bigger ball that you can already find a typical gym, and it apparently gives you ridiculous abs and a sports bra.
Research and Development:
There is nothing funny at all about developing core strength. A woman naming a shitty kid's ball after herself and selling it as a health product? That's pretty ballsy, even for master trainer Leslie Bender.
The Bender Ball sells for $9.99, which is reasonable except that the kid version costs like $2. One concern is that you have to inflate the Bender Ball yourself with a straw. As one reviewer writes, "It hard to get a firm ball." A truer statement, if spoken, would unleash the rapture.
