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 are just guessing what you can do. 4DP™ knows exactly what you’re capable of across a range of efforts and uses your complete power profile to tailor every target in every workout. You get the precise training stimulus necessary to get faster. 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 to train his elite athletes. Grounded in cutting-edge sports 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.

With options for novice, intermediate, and advanced riders—and integrating bot outdoor and indoor workouts—we have a plan to get you faster.

  • Integrated Approach

    Getting fast isn’t just about training on the bike. Our plans integrate structured cycling workouts, full-body yoga sessions, strength training, and mental toughness exercises to make you strong, flexible, focused, and mentally tough. The competition doesn’t have a chance.


YOGA FOR CYCLISTS

Getting faster on the bike means getting stronger off it. Our Yoga for Cyclists videos, created with Abi Carver at Yoga15.com, will help you build core strength and flexibility, improve your posture, reduce the chance of injury, and help you stay calm and focused under pressure. Come for the Suffering, Namaste for the yoga.


MENTAL TOUGHNESS

Courage and fear. Confidence and doubt. Winning and losing. The difference, more often than not, is a state of mind. Developed with sports psychologists and elite coaches, our new mental toughness Programme brings you practical, no-nonsense tools to build your mental toughness.


STRENGTH TRAINING FOR CYCLISTS

Stronger is faster. Increase your power, improve your endurance, and reduce your chance of injury with a strength training programme designed specifically for cyclists.

Never thought I'd be a yoga convert but here I am! As a full-time working mom the likelihood that I would ever get to a yoga class is slim to none, but I can do 15 minutes. My flexibility has improved and so has my core strength. Thanks, Sufferfest!

—Janis D.
