Stretching before exercise prevents injuries

Stretching before training does not meaningfully reduce injury risk. A large randomized trial and two meta-analyses found no protective effect, while strength training cut sports injuries substantially. Stretch if you want more range of motion; for injury prevention, warm up and get stronger.

What the science says

  • Pre-exercise stretching reduces injuries Limited evidence

    Pope's 2000 randomized trial allocated 1,538 army recruits to stretch or not during their warm-up for 12 weeks. Injury rates were essentially the same (hazard ratio 0.95), with no significant effect on soft-tissue or bone injuries.

  • Pooled trials show no protection from stretching Strong evidence

    Thacker's 2004 systematic review found stretching was not significantly associated with fewer injuries (odds ratio 0.93), and Lauersen's 2014 meta-analysis of 25 randomized trials with 26,610 participants found no benefit for stretching (relative risk 0.96).

  • Strength training does prevent injuries Moderate evidence

    In Lauersen's meta-analysis, strength training programs reduced sports injuries to less than a third (relative risk 0.315), and proprioception training also helped. The number of strength trials was small, so the size of the effect is uncertain, but the direction is consistent.

What to do instead

Use a general warm-up before training and strength-train regularly; stretch for flexibility goals, not as injury insurance.

Warm-up5-10 minutes of light cardio plus lighter warm-up sets of your first lift
Injury preventionStrength training 2-3 times per week
Balance and proprioceptionUseful in sports with jumping and cutting
StretchingOptional; if you want range of motion, 2-4 sets of 20-30 seconds per muscle, any time
Build load graduallyAvoid sudden jumps in training volume

Who should be careful

This page covers injury prevention in healthy adults. If you already have an injury or recurrent pain, see a physician or physical therapist rather than relying on general advice.

Frequently asked questions

Should I stop stretching before training?

Stretching is not harmful in moderation, but it does not prevent injuries: a trial in 1,538 recruits and two meta-analyses found no protective effect.

What does reduce injury risk?

In a 2014 meta-analysis, strength training cut sports injuries to less than a third, and proprioception training also helped.

Is stretching useless then?

No. It can improve range of motion if that is your goal; it just should not be counted on for injury prevention.
