There’s a category of athlete that clinics see constantly and that almost no training advice is written for.
You’re not training for anything. You’re not on a program. You play — tennis on Tuesday evenings, a doubles match Saturday morning, a summer league, a pickup game, a softball season.
You play hard when you play. And between sessions, you do essentially nothing athletic.
That pattern has a specific physiology and a specific set of injuries attached to it. Here’s why, and what to do about it without becoming someone who trains.
The Structural Problem
Think about what a competitive recreational match actually asks of you.
Repeated sprints. Sudden stops. Lateral pushes off a loaded leg. Rotation under speed. Overhead reaching at full stretch. Sometimes two or three hours of it, in August heat, with the intensity that only comes from actually caring about the result.
Now think about what preceded it. For a lot of people: a working week spent sitting, and the last comparable effort seven days ago.
You are performing maximum-effort athletic movements from a baseline that hasn’t been prepared for them. That’s not a moral failing — it’s simply an accurate description of the gap, and the gap is where injuries live.
Why “I Play Twice a Week” Isn’t Training
Playing does several things well. It builds sport-specific skill, it maintains some cardiovascular fitness, and — importantly — it’s enjoyable enough that you keep doing it, which is more than most training programs achieve.
What playing doesn’t do:
It doesn’t build strength. Sport uses whatever strength you have; it doesn’t systematically develop more. Nothing in a tennis match progressively overloads your calves or your glutes in the way that produces adaptation.
It doesn’t build tissue capacity for the demands it makes. Your Achilles is asked for explosive push-off during play, and never prepared for it between sessions.
It doesn’t progress. Fitness improves when demand increases over time. Playing the same two matches a week for five years applies roughly the same demand in year five.
And it doesn’t address what’s declining. Power in particular fades with age faster than general strength when nothing is done about it — and power is precisely what a first step, a jump for an overhead, or a lateral push-off depends on.
The Injuries This Pattern Produces
Look at the injuries that cluster in middle-aged recreational sport and the pattern is consistent.
Calf and Achilles injuries. Achilles ruptures occur most commonly in middle-aged people during sports involving bursts of jumping, pivoting and running — tennis, racquetball, basketball and badminton being the ones repeatedly named. One study tracking rupture rates over time concluded the increase in the athletic group was explained largely by increased participation in recreational sports.
Hamstring strains, which predominantly occur during high-speed running — something most recreational athletes only do in matches.
Shoulder problems, from serving and overhead work performed with rotator cuff and scapular muscles that never get trained.
And a general category of things that go on the second or third hour, when fatigue degrades control.
The common thread isn’t the sport. It’s explosive demand placed on tissue that hasn’t been prepared for explosive demand.
What Actually Helps, Realistically
The advice “train more” is unhelpful if the reason you play recreationally is that you don’t want a training life. So here’s the version that fits a real schedule.
Two sessions a week. Twenty to thirty minutes each.
That’s the whole prescription. Not two hours in a gym, not a program with phases.
What those sessions should contain:
Calf raises, heavy, both straight-knee and bent-knee. If you play a court sport, this is the single highest-value item. It’s the tissue most likely to fail and the one most reliably undertrained.
A hinge pattern — deadlifts, or hip thrusts — for the posterior chain that produces your push-off and protects your hamstrings.
A squat or split squat pattern, loaded, for the legs that decelerate you.
Some pushing and pulling for the shoulders, and specifically external rotation work, since everything you do all day works the internal rotators and almost nothing works the external ones.
And something explosive, done fresh rather than at the end — skipping, small hops, brief accelerations. This is what maintains the quality that fades fastest, and it’s what prepares you for a first step in a match.
Progress it. Add load or reps every few weeks. A program that never gets harder is maintenance.
The Non-Negotiable Ten Minutes
If you do nothing else from this article, do this one.
Warm up before you play. Properly.
Not four practice serves. Ten minutes: easy movement to raise your temperature, some leg swings and lunges, a few gradual accelerations building to near-full speed, and a few sport-specific movements at increasing intensity.
Why it matters more for you than for a competitive athlete: they’ve been moving all week. You’ve been at a desk. Your first genuinely explosive movement of the week should not be a competitive point.
Inadequate warm-up appears repeatedly among contributing factors for exactly the injuries this population sustains.
Managing the Session Itself
Watch the third hour. Most recreational injuries happen late, when mechanics have quietly degraded and you’re still competing at full intensity. Decide your finishing point before you start, not when you’re tired — fatigue impairs precisely the judgment you’d need to make that call well.
Be honest about back-to-back days. A tournament weekend or two matches in two days is a substantially different demand from your normal week, and it needs preparing for rather than absorbing.
And factor in August heat. Adjust intensity by feel rather than by what you’d normally manage, hydrate to thirst, and stop for dizziness, nausea, headache or confusion — heat illness and fatigue compound each other, and both raise injury risk.
The Reframe Worth Making
The most common objection I hear to any of this is some version of: I play for fun, I don’t want it to become a project.
Which is completely fair. But consider what the alternative actually costs.
An Achilles rupture takes you out for the better part of a year. A hamstring strain costs weeks and carries a substantial reinjury risk. A calf tear ends your season.
Two half-hour sessions a week is a smaller commitment than any of those. It’s not about becoming an athlete — it’s about being able to keep doing the thing you actually enjoy, for another twenty years.
The people still playing competitive doubles in their seventies are, overwhelmingly, the ones who did something between matches.
Signs Worth Acting On
Get assessed for pain persisting more than two weeks despite backing off; pain that’s worsening session to session; anything that changes how you move; swelling; a joint that gives way or locks; or a niggle that reappears every season in the same place.
Seek urgent care for a sudden pop with loss of function; inability to bear weight; calf pain with swelling, warmth or redness; or any fall with a head injury.
And seek emergency care for chest pain or pressure, unusual breathlessness, dizziness or fainting during play. The social framing of recreational sport conceals genuine cardiovascular demand, and if you’ve been largely inactive or have cardiovascular risk factors, speak to your physician before ramping up.
Get Ahead of It
The end of summer is a reasonable moment to take stock — before the fall leagues, and before something forces the decision.
Sports PT Centers offers a free discovery visit at no cost and no obligation. You’ll get an assessment of your strength, power and movement, an honest read on where your gaps sit given how you actually play, and a program that fits into two short sessions a week rather than taking over your life.
