If your young athlete is training six days a week and still stalling, the missing piece usually isn't another session. It's recovery. Here's how overtraining quietly stalls young athletes, and how much rest they actually need to keep improving.
A parent pulled me aside after a session last month, frustrated and a little scared. Her daughter plays club volleyball, works with a private coach twice a week, lifts on her own, and just made her school team. On paper she's doing everything right. The problem is that her vertical has stopped climbing, her knees ache most mornings, and she snapped at her mom in the car on the way to a tournament for the first time anyone could remember. The mom wanted to know what they were missing. What drill, what supplement, what extra session would get things moving again. My answer caught her off guard. Your daughter doesn't need to do more. She needs to recover.
That conversation happens more often than you'd think, and it almost never starts with a lack of effort. The young athletes I worry about aren't the lazy ones. They're the ones grinding seven days a week with no margin built in anywhere. When a kid's progress stalls, gets hurt, or loses their spark, the reflex is to add something. More reps, more reps, another lesson, another camp. A lot of the time the real fix is the opposite, and it's the one nobody wants to hear.
Here's the part that gets lost. Training doesn't make you stronger or faster on its own. Training is the stimulus. It's a signal that tells the body it needs to adapt. The actual adaptation, the stronger muscle, the higher jump, the faster first step, happens afterward, while the athlete is resting and sleeping and eating. If that recovery window never comes, the signal keeps firing but the body never gets the chance to bank the gain. You end up working harder and harder for results that stop showing up.
For a young athlete this matters even more than it does for an adult, because they're not just recovering from training. They're still growing. Their bodies are pouring resources into building bone and adding height and wiring up a nervous system, and a lot of that work happens during sleep. Pile heavy training volume on top of all that with no real rest, and something has to give. Usually it's the very performance the family was chasing in the first place.
Overtraining in young athletes rarely announces itself. It creeps in. The clearest early sign is performance that stalls or slides backward even though the kid is working as hard as ever, because that's the body telling you it can't keep up with the demand. Nagging aches that linger for weeks, especially in knees, shoulders, elbows, and the lower back, are another flag, and they often show up before any real injury does. I've written before about how [most volleyball injuries aren't accidents](/blog/most-volleyball-injuries-arent-accidents) but the predictable result of load the body wasn't prepared to handle, and chronic overtraining is exactly that pattern playing out slowly.
The signs aren't only physical. A kid who's getting sick more than usual, sleeping badly, dragging through the day, or getting unusually moody and short-tempered is often a kid whose system is overdrawn. And then there's the quietest sign of all, the one that should scare a parent more than a sore knee: the sport stops being fun. Burnout looks like a young athlete who used to love going to practice and now finds reasons not to. Once that joy drains out, talent doesn't keep them in the game, and plenty of genuinely gifted kids walk away in their mid-teens for no other reason than they were exhausted.
Let me give you something concrete. At a minimum, a young athlete needs one full day each week with no organized training at all, and for most kids two is better. They need a genuine off-season too, meaning several weeks each year away from their main sport where the body and the mind both get to reset, not a single week off before jumping into the next season. Sleep is non-negotiable and almost always the first thing to get cut: teenagers genuinely need somewhere in the range of eight to ten hours, and a kid running on six is not going to adapt to training no matter how hard they go.
The hardest one for families to manage is total load. When a kid plays on two club teams, trains privately, lifts, and plays for the school, no single coach sees the whole picture. Each one only sees their slice and reasonably asks for a little more. Added up across the week, it becomes a volume no developing body can absorb. Somebody has to step back and look at the entire schedule, because the total is what the kid's body actually has to recover from, not any one piece of it.
None of this means doing less and hoping for the best. It means trading junk volume for the work that actually pays off, and then protecting the recovery that turns that work into results. A smart, age-appropriate strength program a couple of days a week is the highest-return training a young athlete can do, because a stronger body tolerates load better and gets hurt less. I've laid out what that looks like in a piece on [how often high school athletes should lift weights](/blog/how-often-should-high-school-athletes-lift-weights), and the honest answer is that it's less than most people assume and more effective for it.
Beyond that, the priorities are simple to name and hard to hold to. Guard sleep like it's part of the program, because it is. Build real rest days into the week and a real off-season into the year. Keep an eye on total weekly volume across every team and coach, not just one. And resist the fear that backing off means falling behind, because the kids who burn out at fifteen fall a lot further behind than the ones who took a day off. If the schedule itself is the problem, that often traces back to a deeper issue I covered in [why your kid doesn't need to pick one sport yet](/blog/your-kid-doesnt-need-to-pick-one-sport-yet).
I coach a lot of young athletes and their families across South County and the broader St. Louis area, and the ones who improve year after year are almost never the ones training the most. They're the ones training smart and recovering on purpose. If you want help building that kind of plan for your athlete, one that develops them without running them into the ground, take a look at our [team training program](/services/team-training) and let's talk about what it could look like.

Work With Our CoachesEvery season I get the same question from parents: should my kid drop everything and go all-in on one sport? Almost always, the honest answer is not yet. Here's what early specialization actually does to a young athlete, and what builds a better one.
Jumper's knee, rolled ankles, cranky shoulders. Most coaches treat these as bad luck or part of the game. They're not. The vast majority of volleyball injuries are predictable, and that means they're preventable.
