Step Mill Interval Training

I used to avoid this machine like the plague because I thought it was pointless however, I have grown to love it! Also come to find out it really gives you a great cardio workout considering I barely lasted 15 minutes the first time I started interval training. After a few weeks I have worked my way up to a decent 30 minute workout that burns some serious calories. Here's my Step Mill Interval Workout! Enjoy and good luck!
