I have a manual treadmill that I got for very little, but I found that the belt does not move very well. If you don’t put it on the highest incline, it just doesn’t move.
Is there some sort of lubricating or Teflon substance I could put on the bottom of this belt to make it slide better? I tried this white lithium grease spray, but it just made it even worse, maybe because it was still sort of wet.
