  • too much lumbar hyperextension, the ball should be a bit closer to the wall so that the lever is longer. Pause and stabilize, don't bounce using the elastic qualities of the ball

  • I purchased this ball yesterday and it say's 250 weight limit. I weigh 256 will it still hold up well!? Thank you for your time and please respond ASAP!

  • what a milf

  • Thanks. The hyperextension bench is always being used by someone at my gym.

    This should be a good alternative.

  • this is hot

  • This really strengthens the back - it works!

  • this is work!!(:
