There are some people who have this kind of problem which I fully understand. There are just some problems when it comes to the ground and it's structure. This is probably the reason for your issues with this kind of thing but there are just some aspects that we have to take a look at with this issue because it is messing up your routine lol. I know that it is a therapeutic thing and if there are issues it hampers the experience to the point that there are some misgivings about the machine which possibly has some issues too.
