We're not going to lie. This will in no way, shape or form be an enjoyable experience. The title should have told you that already. But if you're really dedicated to performing at your best, overcoming all obstacles, and pushing through to that next level, then the Spinerval The Pain Cave DVD Competition Series 33 training video is the right one for you. You'll go on a fitness quest with Coach Troy to discover what your threshold really is. You'll start off with some pedaling technique drills, then gradually build intensity to some threshold work, and then finish it off with some delightful, leg-searing sprints. You'll hate nearly every minute of it, but you'll develop some massive power output and wickedly improved endurance.
