A couple of years ago, Mark Twight from Gym Jones introduced me to the 30/30 interval workout. Go hard for 30 seconds, go easy for 30 seconds. Repeat. Or so I thought. Although I came to really like this workout, it turns out that I really did not understand the concept and performed them incorrectly. It's no wonder that I liked them as much as I did. Going really easy during the rest interval allows for decent recovery and makes you feel pretty damn strong during the work bouts. I don't think performing them in this fashion is a complete waste of time but, as you will see, performing them correctly is a different beast.
