The 10-Minute Warm-Up and 5-Minute Cool-Down

Most tennis injuries happen either in the first 15 minutes of a session (cold-body injuries) or in the 24 hours after (stiffness-related). A proper warm-up and cool-down prevent both — and take less time than most club players spend on their phone before hitting the court.

Quick answer

The 10-minute warm-up: 3 minutes of dynamic movement (leg swings, arm circles, lunges), 4 minutes of light rally from the service line, 3 minutes of gradual full-court rally. Then 5–10 easy serves before any real serving. The 5-minute cool-down: 3 minutes of walking + light stretching, 2 minutes of static stretches for hip flexors, hamstrings, and shoulders.

The warm-up structure

Minutes 0–3: Dynamic movement

• 10 leg swings each leg (front-to-back, then side-to-side)
• 10 arm circles each direction
• 10 walking lunges
• 10 side-to-side shuffles
• 5 slow squats
• 20 seconds of light jogging or high-knees

You should feel warm and slightly sweaty by the end.

Minutes 3–7: Mini rallies

Start at the service line with your partner. Rally soft. Focus on:

• Clean contact
• Full follow-through even at low pace
• Smooth footwork, not standing still

Minutes 7–10: Full-court rally

Move to the baseline. Rally at 70% pace. Do not go straight to full pace or hard serves.

Serves: 5–10 easy ones

Before hitting a single full-pace serve, hit 5–10 at 40% pace, gradually building to 70%, then to 100%. Cold shoulder + full pace serve = injury.

The cool-down structure

Minutes 0–2: Walking

Walk around the court twice, letting your heart rate come down. Do not sit down immediately — that pools blood in your legs.

Minutes 2–5: Static stretches

Now you can stretch. Target the tight areas:

• Hip flexors: kneeling stretch, 30 seconds each side
• Hamstrings: seated forward fold, 30 seconds
• Calves: wall stretch, 30 seconds each
• Chest and shoulders: doorway stretch, 30 seconds
• Wrists: finger-back stretch, 20 seconds each

Post-play (within 30 minutes)

• Water — you're more dehydrated than you feel
• A snack with protein + carbs
• Ice any acute sore spots for 10–15 minutes

Why static stretching before play is wrong

Research over the past 20 years is clear: static stretching before dynamic sport (tennis, running, jumping) actually reduces power output and does not prevent injury. Save static stretching for AFTER.

Dynamic movement — the leg swings and lunges — is what prepares muscles for high-load work.

Cold weather adjustments

If it's under 50°F on court:

• 15-minute warm-up minimum, not 10
• Extra layers during warm-up, remove as you heat up
• More easy serves — 15–20 before full pace
• Consider a warm-up jacket during changeovers

Cold muscles + hard tennis is how you strain a hamstring or tweak a shoulder.

Warm-up when you're rushed

If you only have 5 minutes:

• 90 seconds of dynamic movement (skip the details, just move)
• 2 minutes of mini rallies
• 90 seconds of gradually harder rally

Skip the serves entirely if you can't warm up your shoulder. Play out one game as a warm-up game if your partner agrees.

Common warm-up mistakes

• Straight from the car to serving. Highest injury risk of anything you can do in tennis.
• Static stretching first. Reduces performance, doesn't help injury.
• Warm-up hit is your first "real" hit. Treat the warm-up as sacred — no chit-chat, focus on the balls.
• Not warming up serves separately. The shoulder needs its own progression, not just the groundstrokes.

Cool-down for older players

If you're over 40, the cool-down matters more than the warm-up. Skipping cool-down leads to next-day stiffness, which leads to compensations, which leads to injury.

Add:

• 5 more minutes of stretching for whichever areas felt tight
• A hot shower or bath within an hour
• Light activity the next day (walk, easy bike ride) instead of complete rest

For juniors

Juniors need less warm-up (5 minutes is often enough) but MORE emphasis on dynamic movement and stretching for growth-related tightness. Never let a junior serve without at least 3 minutes of arm and shoulder mobility.

Making it a habit

The warm-up and cool-down only work if they're automatic. Do them EVERY time, even for a 30-minute hit. If you skip them "just this once," you'll skip them regularly.
