Has any body had experience with this type of trainer It seems the resistance comes on quickly not progressive I was spinning on it yesterday for a 10min warm up before some 30sec intervals & half way thru warm up it started getting harder while i was spinning ...seems unusual can it be a fault. I would expect the resistance to built if i was sprinting.
My kids usually use it , first time i used it yerterday to get back some fittness for crits..
