Stretching advice for kids' sport is often outdated — many of us grew up being told to hold a stretch before running out onto the pitch, which modern sports-safety guidance no longer recommends in that form. The short version: movement-based (dynamic) stretching before activity, held (static) stretching after — and neither needs to take more than a few minutes.
Dynamic stretching: before activity
Dynamic stretches move a joint through its range of motion rather than holding a position — leg swings, walking lunges, arm circles, torso twists. Done as part of the warm-up, this gradually prepares muscles and joints for what's about to happen, without the temporary power reduction that can come from holding a deep stretch while still cold.
Static stretching: after activity
Static stretching — holding a position, like a hamstring or calf stretch, for 15-30 seconds — is better placed in the cool-down, once training or a match has finished. At this point, muscles are warm, and static stretching can help with general flexibility and post-exercise comfort over time, without the pre-activity power-output downside.
A simple post-training stretch routine
Five minutes, covering the areas young athletes use most:
- Quad stretch — standing, pull heel toward the glutes, hold 15-20 seconds each side.
- Hamstring stretch — seated or standing, gently reach toward the toes with a straight-ish leg, hold 15-20 seconds each side.
- Calf stretch — hands against a wall, one leg back with the heel down, hold 15-20 seconds each side.
- Hip flexor stretch — kneeling lunge position, gently push hips forward, hold 15-20 seconds each side.
- Shoulder/chest stretch — arm across the body or behind the back, hold 15-20 seconds each side.
None of these need to be pushed to the point of pain — a gentle pull is the target, not intensity.
Is stretching actually necessary for kids?
Children and younger teenagers are generally more naturally flexible than adults, so stretching matters less for them than it does for a fully-grown athlete — but it's still a useful habit to build early, both for the modest flexibility benefits and because it establishes a proper warm-up/cool-down routine that becomes genuinely important as training intensity increases through the teenage years.
What to avoid
Forcing a stretch to the point of pain. A young, still-developing body doesn't need — and shouldn't be pushed toward — adult-level flexibility through force. Discomfort is fine; pain means stop.
Long static holds immediately before intense activity. Save these for after — see the dynamic-vs-static split above.
Bouncing while stretching ("ballistic" stretching). Static stretches should be held steady, not bounced, which raises strain risk for little added benefit.
Frequently asked questions
Should my child stretch every day, even without training? It's not necessary, though general daily movement and play does most of the same job for younger kids. Focus stretching specifically around training and match days.
My child's coach has them do static stretches before training — is that wrong? It's an older approach that's fallen out of favour in sports-safety guidance, but it's not dangerous in itself — the main downside is a possible small, temporary reduction in power output right after long held stretches. Worth a friendly conversation with the coach if it's a concern, not something to worry about as a safety issue.
Does stretching prevent injuries? The evidence is more mixed than commonly assumed — a proper warm-up (see our Warm-Up guide) does more for injury prevention than stretching alone. Stretching is still worth doing for flexibility and habit-building, just not as the primary injury-prevention tool.
At what age should stretching become more structured? As training intensity increases through the teenage years — roughly from ages 12-14 onward as sessions get longer and more demanding — a proper warm-up and cool-down routine, stretching included, becomes more genuinely important than it is for a 6-8 year old playing more casually.
