I wrote this for a few guys I'm training who wanted something spicier than steady state cardio. It's a pretty straightforward High Intensity Interval program on a bike, but you don't have to use a bike. I actually use the Stair Mill and just vary the intensity. Stair mill is actually crazy because I have to concentrate on not falling, but still... it can be effective if you have the bandwidth and are bored with just treadmill. Sound off below if you like the HIIT routine and if you'd like to see more stuff like this!

Let's get to know each other! Who are you and what are you getting ready for?
