What is Four-Dimensional Power™?
Training apps that base power targets only on your FTP are just guessing at what you’re capable of above threshold. Not The Sufferfest. We use four key metrics—Neuromuscular Power, Anaerobic Capacity, Maximal Aerobic Power and Functional Threshold Power—to create your complete power profile. We then generate personalized power targets for all of your workouts, giving you exactly the training stimulus you need to get faster. Those other apps don’t know you like 4DP™ does.
4DP™: Four Does More
Why is FTP, which only measures your aerobic power, an inadequate measure of your fitness? Because cycling isn’t just about long, sustained efforts. It’s about attacks, surges, sprints and breakaways. It’s about being able to recover and hit it again. That’s why our Four-Dimensional Power™ profile captures your performance across all four of your key energy systems:
Neuromuscular Power is pure sprinting ability.
Anaerobic Capacity is for short, sharp efforts.
Maximal Aerobic Power is sustained power over a few minutes at VO2 max.
Functional Threshold Power measures endurance ﬁtness.
