Four-Dimensional Power™: The Most Effective Workouts Available

4DP™ will change the way you train. Our comprehensive fitness test goes beyond FTP, using four distinct metrics to reveal who you are as a cyclist and personalize every target in your workouts to match your unique profile. No other training app can do that.

  • Find Your Hidden Power

    4DP™ measures your neuromuscular power (NM), Anaerobic Capacity (AC), Maximal Aerobic (MAP) and Functional Threshold Power (FTP) to determine what you’re capable of across a range of efforts. The app will then assign you a rider type—Sprinter, Attacker, Pursuiter, Time Triallist, Climber, or Rouleur—and personalise your power targets to match your unique profile. Specific workout recommendations will help build your strengths and address your weaknesses.

  • Your Targets, Your Workouts

    Training apps that just use FTP to set power targets have to guess what you can do. But 4DP™ knows exactly what you’re capable of and uses knowledge to tailor every target in every workout so you get the exact right training stimulus. No more wasting time on workouts that don’t work.

  • Race Proven

    4DP™ uses the same testing and workout personalization protocol developed by world-class coach Neal Henderson of APEX Coaching to train his elite athletes. Grounded in science, verified by rigorous lab testing, and proven by victories in the most prestigious events in the world such as the Tour de France, World Championships and the Olympics. 4DP™ puts race-winning, individually-optimized training in your hands.
