I was given Stuart McGill’s Ultimate Back Fitness and Performance by a client , great book. After reading the chapter discussing this I bring it to you . Personally , Iam not a fan of the weight belt . To me it’s a “wait” and see belt , wait to see how deconditioned your back is after using it. When I see gym goers weraing them I shutter.
Here are some of the key points of Stuart McGill’s research :
If you never injured your back, wearing a belt adds no safety.
If you injure yourself while wearing a belt, the injury is more severe.
To get the most out of weight belts, you must lift with bad technique.
If you want to lift a few more pounds, wear a weight belt.
What do you think ? Friend or Foe ?
