Weightlifting is the Olympic discipline for many years. Long-term and lasting many hours trainings cause chronic pain and spine deformations. Stressed spine while weightlifting can cause intervertebral discs injuries, herniated nucleus pulposus and nerves compression. This pinched nerves cause pain, limbs numbness or tingling and even paresis.

To prevent backbone conditions it is recommended to use our lumbar belt AS-LK-01.

While weightlifting we can observe isometric effort based on Valsalva’s maneuver. During using of our lumbar brace, intra-abdominal pressure (exactly: intra-muscular pressure in the erector spinae muscles) increases what makes the lower spine more rigid and allows to lift more weights.

Using AS-LK-01 lumbar belt causes:

  • Reduction of excessive back muscle tension

  • Risk injuries minimization

Our brace AS-LK-01 supports lumbar spine during physical activities by off-loading your bending backbone. First of all, the belt prevents your spine in case of intensive body building. Also, it supports you in other sport disciplines and daily activities.
