So, I've been wondering, is it okey to exercise if you're tired? and I don't mean like ''oh I'm so tired of this routine and I don't want to try it anymore'', I mean like when you just come home from work after a 10 hours shift, how can affect your health or your weight lost goal?
Hi, I heard if you use the elliptical too much it can enp up hurting your knees. 1. fact or myth? 2.If fact, how much it's too much?
