Due to my feet needing realigning I can't use a treadmill to run on, if I want to run I have to use the cross trainer because my feet don't have to move and therefore less likely to fall, on the treadmill I can loose my balance I have to concentrate too much when running to ensure I don't fall, it's all my feet's fault, until I can get surgery on them I won't be able to run on a treadmill, but who needs a treadmill cross trainers are more fun, anyone gone backwards with one?
