The ability to keep moving well when fatigued is one of the most important parts in endurance performance.


Natural Resistance helps you develop fatigue-resistant movement mechanics, by securing form, posture, and force production long after others begin to break down.

Training with extra weight raises the cost of every movement, and simulates running in a fatigue-induced environment.

With consistent training, your body naturally adapts to the increased demands of the extra weight.

When you finally run without it, you will be able to produce more work, faster, and longer, delaying the onset of fatigue and improving your performance.

The specific body adaptation of running with weight is not that you get more efficient at carrying extra weight, it is that you get more efficient at carrying your own bodyweight.


Running with additional load develops more efficient movement mechanics and fatigue resistance. When the weight comes off, you’re able to maintain form, posture and force production when it really matters.
