Plan Description

Get the 80/20 Endurance Advantage!

Core strength is important for all endurance athletes. Strengthening the muscles in your body’s midsection will help you swim with greater tautness and less drag, cycle with less low-back discomfort, and run with better posture and less energy waste, among other benefits. There’s a reason elite endurance athletes make time for core strength training, and you don’t have to be a Professional athlete to get the same benefits.

80/20 Endurance Core Strength plans are offered in 10 different lengths that match the lengths of our various endurance plans. This allows you to choose, load, and sync a Core Strength Plan with an 80/20 Endurance Plan of equal length.

80/20 Endurance

80/20 Endurance

80/20 Endurance is the creation of Matt Fitzgerald and David Warden. Based on the breakthrough books 80/20 Running and 80/20 Triathlon, runners, triathletes, and other endurance athletes improve the most when they consistently do 80 percent of their training at low intensity and the other 20 percent high intensity. The typical endurance athlete spends only 50-70 percent their total training time at low intensity. The solution? An 80/20 training plan that ensures the optimal intensity balance.
