Join Vili Fifita for four weeks of quick and effective endurance training. This challenge will help you build muscular endurance so you can perform at a higher capacity for longer – and start feeling better with less fatigue.

Before you start, complete the Strength testing. Then, progress through the four Strength workouts in order. Go at your own pace – doing 2-3 workouts per week. Once you’ve done all four workouts start back at number one and keep repeating the series. After four weeks you should notice some serious gains!

Each workout uses equipment, but we’ll also show you options to do without.
