FOR PERSONAL USE ONLY. NOT FOR GYM OR STUDIO USE. At Sufferfest Studios, we make the hardest, most exciting, most suffer-your-ass-off cycling and running training videos in the world. As seen in Outside Magazine, Bicycling, ESPN, Cycling News and Triathlon 220, we are acclaimed as the best indoor training videos in the world. *** Structured workouts: Nothing is worse than getting your bike or treadmill and just slogging away. Regardless of your fitness level, if you want to get strong and fast, then high-intensity intervals are the way to do it. Exciting workouts that get you maximum results in minimum time. *** Clear instructions: All of our instructions are on screen in clear, easy-to-read text. We tell you how hard to ride based on your own 'Perceived Exertion.' We use a 10 point scale, where 1 is lying on the couch and 10 is a flat-out-win-at-all-costs sprint. *** Professional Racing footage: Ever want to race the Tour? Paris-Roubaix? The World Championships? The Sufferfest has them all - and more! Our videos feature footage from the biggest and best races in the world. You'll find yourself climbing against Alberto Contador, sprinting against Mark Cavendish and trying to drop Fabian Cancellara on the cobbles. *** Great Music: Here at The Sufferfest, we LOVE music. So we spend hours and hours finding great music that works with our intense workouts and killer footage. From electronic to indie to rock, there is something for everyone.
