HIIT cardio explained - A GREAT way to run

Thanks for posting this! I had been wondering if its better to do HIIT, or to run slower (very slow if you're me) for a longer period of time.

thanks for the share

thanks for sharing this great information with us!!

HIIT is awesome, but it doesn't have to be just running. It can be done with any kind of cardio. Whether running outdoors, on a treadmill, on an elliptical, a bike, or a rowing machine. Just so you all know!

thanks for this! i was about to ask if i could do this on the elliptical - i still feel very self conscious about the loud "thwamp" noise when i try to run on the treadmill >.>

Just honestly wondering - what is the difference between HIIT and fartlek training in running? Is there a difference?

http://en.wikipedia.org/wiki/Fartlek

Did a quick Google search and found this:

Seems the big difference is HIIT is more regimented in terms of timing your periods of high intensity and recovery, whereas in fartlek training is less structured and more adjustable.

Thank you very much for posting this - I have been trying to get a handle on the HIT stuff and this spells it out very clearly! THANK YOU!

Did this for the first time today! I have no idea how some of you out there can sprint at 12mph...I started my first sprint at 8.0mph and almost flew off the treadmill haha! So I had to keep my "sprints" at 7.5mph. Guess I just have to work my way up.
