Does anyone else feel "mentally" exhausted after a HIIT workout? My body is tired physically but it is like I am semi-brain dead as if I had been up all night.
I have problems going fast enough on the treadmill. I can't seem to get up to "all out" speed without feeling like I am going to fall off so I find my stationary bike (old fashioned kind, not computerized) to be optimal since I have direct control over the speed/tension and don't have to wait for the machine to change speeds like you do on treadmill/elliptical, etc.
Oh and for whoever mentioned they like the Arc Trainer--I just read something about how they are actually very bad on the knees due to lack of complete ROM and moving the knee in a very unnatural way. I will have to go and look again where I read it, some sports medicine site.
