The Truth About Energy Systems: Why Your Training Should Match Your Goal
19m | Aug 13, 2026Why can someone be incredibly strong but struggle to run 5km? Why can a great runner get destroyed by a heavy sled? And why does a powerlifter rest five minutes between sets while a Hyrox athlete barely stops moving?
In this episode of Real Talk Fitness with ANPT, I break down the three main energy systems your body uses to fuel training: the ATP-PC system, anaerobic glycolytic system, and aerobic system.
We dive into how each system works, when your body relies on it most, and why your training needs to look completely different depending on your goal.
Whether you're training for strength, Hyrox, running, fat loss, or overall fitness, you'll learn why more intensity isn't always better, why easy sessions actually matter, why rest periods are part of training, and how to make sure every session has a purpose.
We also cover compromised running, threshold work, Zone 2 training, strength recovery, HIIT, carbohydrates, fatigue, and why trying to train every energy system hard at the same time can leave you exhausted without actually progressing.
The biggest takeaway?
Stop training just to feel tired and start training for the result you actually want.
