What is HIIT

There are a lot of people talking about HIIT, but I am not sure what this is.  Can someone please explain?  (I am new at this)

Hello :)
HIIT - High Intensity Interval Training

I would have a hard time explaining it, but many CC'ers have tried it and given their feedback.
Here is one such thread that discusses it's pro's and cons.

Good luck,

Can you do HIIT and then do a lower intensity cardio workout in the same day?

i do.

just give yourself enough time to recover. if you do hiit correctly, you should be dead afterwards.
