Why you need to understand Energy Systems

One of the easiest things in coaching is making athletes tired. One of the biggest mistakes coaches make is programming for the athlete they wish they had, rather than the one standing in front of them.
One of the hardest things is making athletes better.
Unfortunately, those two things are often confused.

Many coaches can design workouts that leave athletes lying on the floor. Heart rates are high, lungs are burning, and everyone feels like they worked hard.

The problem is that fatigue is not the goal.
Adaptation is.

This is where understanding energy systems becomes essential.
Every training session should have a purpose. The coach should know what system they are trying to develop, how much work that system can tolerate, and what recovery is required before quality starts to decline.

Without that understanding, coaches often fall into a common trap: prescribing workouts that look impressive on paper but function more as tests than training.

A test tells you where an athlete is.
Training is supposed to change where an athlete is.
The two are not the same thing.

Imagine trying to improve an athlete's aerobic capacity but prescribing work at an intensity that constantly pushes them into a glycolytic state. Or trying to develop repeat sprint ability while providing insufficient recovery between efforts. The athlete is certainly working hard, but the desired adaptation may never occur.

The result is often a strange middle ground where athletes accumulate fatigue without maximising adaptation. They work a lot. They suffer a lot. But they do not improve as much as they should.

This is one reason why many athletes feel like they are constantly training hard yet remain stuck at the same level year after year. Their training has become a collection of tests instead of a progression of adaptations.

Great coaches understand that energy systems are not just physiological concepts found in textbooks. They are practical tools that help determine intensity, duration, recovery, and frequency.

They help answer questions such as:
How hard should this effort be?
How long should it last?
How much recovery is needed?
How often can it be repeated?
What adaptation am I actually trying to create?
The better a coach can answer those questions, the more precise their programming becomes.

Because at the end of the day, athletes do not improve from how tired they get.
They improve from the adaptations their training creates.
Understanding energy systems is one of the best ways to ensure those adaptations happen.

Every coach has a vision of what great performance looks like. We all have standards. We all know what elite training requires. The problem begins when we start confusing where an athlete should eventually be with where they are today.

A coach who trains athletes based on where they want to be rather than where they currently are will eventually pay the price for skipping steps.
Not because the athletes are weak.
Not because they lack commitment.
But because adaptation has limits.
The body does not care about the coach's expectations. It only responds to the stress it can recover from.

This is where many athletes break down.
Training loads increase too quickly. Volume accumulates faster than the athlete can tolerate. Recovery is ignored because everyone is focused on the end goal. For a few weeks, everything looks great. The athlete feels motivated. Progress appears rapid.
Then performance stalls. Aches become injuries. Fatigue becomes exhaustion. Motivation disappears. Sessions get missed. The athlete who looked unstoppable a month ago suddenly looks broken.

The mistake was not training hard.
The mistake was assuming the athlete had already earned the right to train at that level.
One of the core ideas behind great long-term coaching is that adaptation must be respected. Athletes cannot skip stages. They cannot borrow fitness from the future. They cannot recover from work they are not prepared to perform.

The best coaches understand that progress is rarely limited by how much work an athlete can do today. It is limited by how much work they can continue absorbing six months from now.

This requires patience.
It requires restraint.
And sometimes it requires holding athletes back when they are asking for more.
Because the goal is not to win this week.

The goal is to keep improving long enough to become exceptional.
Great coaches do not build athletes by constantly pushing the limits.
They build athletes by expanding those limits gradually over time.

The athlete who stays healthy, consistent, and progressing for years will almost always outperform the athlete who tries to rush the process.
Train the athlete you have today. If you do that long enough, you may eventually get the athlete you imagined.
