If you keep up with my exercise log, you’ll see that I’ve taken up “hurricane training” as part of my cardio routine.  Was immediately attracted to hurricane when I read it in Men’s Fitness because it’s a conditioning tool that a lot of MMA athletes use, and because it’s based of the HIIT routine that Larry initially described on his blog.

Read the article for the full description.  I’ve only done Category 1 (Category II sounds too beast, and too hard to get on and off the cardio machine).

I do my sets on the elliptical trainer, and I try for 30-second sprints, instead of 15-sec, for a total of 10 sprints.  It takes about 25-30 minutes, depending on how much rest I’m taking. 
It’s a little tough to measure my heart rate when I’m up on the elliptical, but usually 60 to 90 secs of rest between sprints is good.

After my first Hurricane session since coming back from NY, I dropped in weight AND body fat % for the first time (usually only 1 will decrease, while the other increases)….for 2 days in a row!

Give it a shot!
