Mt wife has the tread mill that has been in about 5 homes,......i carried
it up the stairs...she has used it about 2 hours,so this is a low milage tread mill.......I get my exersize from stubbing my toes on it ,making those groggy bathroom trips.....i do a little pain dance on one leg when i hold the other one's throbbing toe......The yelling alone is a good exersize,plus the profanities you come up with are amazing......
