You must tell me YOUR secret on doing HIIT for an hour straight ... after 20 min., 30 min max of full on High Intensity, I know many peope will keel over ... do you track your HR?Aries13 said:**Good Morning Everyone**
8am: 1 hour HIIT---20min abs
When I run stairs/toboggan slides, I can get my HR easily over 200 (NOT that I EVER recommend that people!)
I'm curious as to what you do & how intense you go esp. if it's over 30 minutes, of High Intensity Intervals?
