HIIT is so killer but it pays off if you can force yourself to work through the pain. I will have to work my way up to this circuit (or something of similar difficulty). I'll bet you'd kick my butt if I tried to keep up.
I thought this was a great statistic: "27 minutes of HIIT 3x per week is = 60 minutes of jogging 5x a week". I'll take less than 90 minutes of HIIT over 5 hours of jogging every time!!! Thanks again fitchick!
Awesome statistic, thanks for sharing! It is true - the time people spend doing regular cardio is SO much longer than a session of HIIT and they don't quite get all the benefits either. More like tired muscles and a tired body! I know that you are from an area around me - maybe we could workout sometime together and I could motivate you through a HIIT session with me :)
