Is the wiggling of treadmill belt alright i.e it moves like snake from left to right continuously? I am trying to buy a treadmill replacing the old one, but i have noticed that belts have slight movement in them that they shift there position from left to right and Vice versa if you look closely. Sometimes movement is very slight
It is my understanding that belt should move in straight line otherwise on high speeds it might hurt the knee because when foot is in the air and then it lands on the belt it might jerk towards the movement of the belt and there by hurt the knee in due course. I asked this question to the machine vendors they said although massive movement of this kind can be curtailed but slight to very slight wiggle will still remain
I am very skeptic about this. would some expert technician on treadmills please clarify my doubt as i am not satisfied by the answers I am getting. I would like to point out that I am aware of the belt movement towards only left or only towards right that can be set right by adjusting the belt from behind sockets with wrench key.
But I am not talking of that movement. I am asking about the movement of the belt that it moves from one side to another continuously giving it an effect as that of a wave/snake/tyre bubbling just to name a few if I am making my point clear. I have checked videos on youtube but there are not many which focus on the movement of the belt. in some that there are I can notice very slight movement of this kind if not much still. I am very confused.
