What's the ideal interval between the sprints? Right now I'm going for 45 min, with a sprint session that lasts 20 seconds every 5 min, for a total of 8 sprints (and they're pretty much everything I've got for the 20 seconds) - the recovery time seems pretty good, I just wanted to check what the ideal times/durations are.

Also, would soccer be considered a HIIT activity? Back in the states I usually play 1-2 times per week, and I'd think that, by definition, it's ideal for HIIT. Your thoughts?

Did you read the HIIT faq?

FAQ's my friend

Uh....yeah.....thanks for the help fellas....

Nothing in the stickies above regarding HIIT.....did manage to find something in the "running and cycling" forum.

No real posts on soccer in there either...

This, personally, is what i do, and is, evidently, the correct version of HIIT
