I had an eighth-grade athlete who, after every session, would disappear into the bathroom and come out with a soaking wet face. I noticed it for a while before I finally asked him about it.
His answer stopped me.
He told me that if he didn’t look like he’d been working hard, his mom would tell him on the car ride home that he hadn’t gotten a good session — and that I needed to push him harder.
His goal was to improve his speed.
This story captures one of the most common and costly misunderstandings in youth athlete training: the belief that exhaustion is the measure of a good session. It’s not. And depending on what your athlete is actually trying to develop, it can actively work against them.
Training for Fatigue vs. Training for Adaptation
These are two fundamentally different things, and they require two fundamentally different approaches.
Training for fatigue is straightforward. Push the athlete hard, run them until they’re gassed, make sure they leave the session tired. Anyone can do this. There’s a time and a place for it — conditioning work, for example, is intentionally fatiguing. But fatigue is the stimulus, and the adaptation it produces is improved conditioning.
Training for adaptation (specifically for speed, quickness, agility, and first-step improvement) works differently. These are gross motor skills. Teaching them requires attention to detail, clear coaching cues, and an athlete who is physically and neurologically capable of absorbing what’s being taught.
A fatigued athlete can’t do that. When the body is tired, it defaults to the movement patterns it already knows. You’re not reprogramming anything, you’re just reinforcing old habits under stress. You’ll always get what you’ve always got.
What Adaptation Actually Requires
Before every training session, I’m asking four questions:
What is the goal? Speed development, conditioning improvement, strength, power — the objective has to be clear before anything else.
What is the stimulus? Given the goal, what’s the specific approach? How do we structure the session to produce the adaptation we’re after?
What response do we want to elicit? What should the athlete be getting better at by the end of this session? What’s the measurable outcome?
How does the athlete recover? Recovery is part of the training process. The adaptation happens during recovery, not during the session itself. A plan that ignores recovery isn’t a complete plan.
These questions aren’t complicated. But they require a coach who has thought through the process before the athlete sets foot on the field.
Not Every Athlete Can Do What You Ask Right Away
One more thing worth saying: at the beginning of a training program, not every athlete can execute what a coach is asking of them. That’s not a failure — it’s expected.
Learning new movement patterns takes time. There’s a process the athlete has to go through to absorb the teaching and then apply it in an efficient movement pattern. Rushing that process — or burying it under fatigue — doesn’t accelerate development. It undermines it.
The foundation of good training is great coaching, attention to detail, and teaching proper movement patterns before anything else. Everything else builds on that.
What This Means for You as a Sports Parent
A session where your athlete comes home exhausted and can barely move isn’t automatically a good session. Neither is one where they come home feeling fine, but the goal was speed development and the coaching was sound.
The better question isn’t “did they work hard?” It’s “did the session match the goal?”
Ask your athlete’s coach what the objective of each session is. Ask what adaptation they’re trying to produce. A coach who can answer those questions clearly is a coach who has thought through the process. That’s the coach you want training your athlete.
Training with a Plan
At Carlisle Performance, every session is designed around a specific objective. Whether your athlete is working on speed development, strength, power, or conditioning, the training stimulus is matched to the goal — not to how tired they look when they leave.
Strength Power & Explosion is built for athletes who are ready for intentional, progressive performance training. 1:1 Private Coaching is available for athletes who benefit most from individualized attention and a program designed specifically around their goals.
