Initially fit this belt super, just now I got the strap on the tightest setting brought and he still does not sit so well. I'm not exactly slim, still have to 10kg overweight. How does this belt with whom normal weight? In addition, I notice again and again that my elliptical machine to belt "loses". At first nothing was visible. The last 3 sessions however, examined my Syros constantly the readings. As long as I have the belt also not that I could tell, the battery is dead. Only when I stand 45 minutes for the CT and me a Abstrampel, then I can not have nen pulse of 75.
