There are a few signs you may need to adjust your treadmill running belt. The most common sign is when your walking belt has shifted to one side or is about to start rubbing against the side of your exercise equipment.

Your treadmill belt may be slowly drifting too far to the right or left, and this can cause the belt to stretch unevenly. 

You might also notice that when you are walking or running on your treadmill, the belt feels like it’s stalling or having trouble turning over. 

Another sign that a Life Fitness tread belt might need adjustment is when it works fine with a lighter person, but starts slipping with a heavier user.
