My Favorite 'Cardio' Workout

This one is simple, FAST, and effective. You'll burn significant amounts of calories before you even know it, you can do it on a bike, treadmill, outside, or ellipical, and it will never get boring. What could be better?

My Favorite.

10 min. workout

2 min. warmup at any pace (it's a warm-up--don't go too fast--I usually do level 5 out of 20).

Now for a couple of definitions.

Sprint: Raise resistance and/or speed. For example, on a bike go up to level 15 and double the RPMS.

Rest: This is an active rest. Lower back down the level (to the warmup level and speed).

The workout:

Remember, you've already done your 2 min. warm-up. For the next 8 minutes, do this:

15 sec. sprint

15 sec. rest

30 sec. sprint

15 sec. rest

45 sec. sprint

15 sec. rest

30 sec. sprint

15 sec. rest

15 sec. sprint

etc, etc. Keep cycling thru it 'till you reach the 10-minute mark.

If you're crazy, go to 15 or even 20 minutes. But I don't suggest that :)

Skip the gym...not the workout.
