Those brief windows of relief in your workout have an incredibly important role in improving your fitness. Your body has an amazing ability to source and burn energy, but it can only do so much untrained. Your fitness levels are connected to your body’s ability to source and burn energy, and generally, the more proficient it is in doing so, the more you can achieve in a workout. The good news – this can be trained, by sticking to the intervals.

In your EYS sessions, you should make sure to stick to the working time and rest time, no longer and no shorter. The workouts at EYS are designed specifically to challenge the body’s energy systems enough so that they get better at sourcing and burning that energy. So embrace the rest, but when a coach tells you to start working, get straight into it! When they say hold on for those last few seconds, HOLD ON! You can do it!
