Massage Guns (Percussive Therapy): What the Evidence Says
What percussive massage devices do for soreness and range of motion — and what they don't.
What percussive therapy is
A massage gun delivers rapid percussive taps to a muscle. It's a convenient, self-applied version of massage, marketed for recovery, mobility and performance. Here's what it actually does.
What the evidence shows
Short-term range of motion. Preliminary· human data Brief use can increase range of motion in the short term — usefully, without the temporary strength loss that long static stretching can cause. Good for feeling looser around a session.
Muscle soreness. Preliminary· human data Some evidence that it modestly eases delayed-onset muscle soreness. Helpful for comfort, not a dramatic effect.
Performance, strength and muscle growth. Marketing claim No good evidence that percussive therapy boosts strength, speed or growth. Its job is comfort and short-term mobility, not adaptation.
How to use one
Short bouts — roughly 1–2 minutes per muscle — are plenty, before training for warm-up mobility or afterwards for soreness. Read the safety box: keep it on muscle, away from bones, joints, nerves and injuries, and don't grind hard.
The honest summary
A massage gun is a genuinely handy comfort-and-mobility tool with modest, short-term benefits. Treat the performance marketing with scepticism and keep sessions brief.

Frequently asked questions
- Do massage guns work?
- For a short-term increase in range of motion and some relief of muscle soreness, the evidence is modest but real. As a way to feel looser and more recovered before or after training, they're reasonable — just don't expect performance gains.
- Do they improve performance or build muscle?
- No. There's no good evidence that percussive therapy boosts strength, speed or muscle growth. Its role is comfort and short-term mobility, not adaptation.
- Before or after training?
- Brief use before can aid warm-up mobility without the strength loss long static stretching can cause; after, it may ease soreness. Both are low-stakes.
- How long should I use it?
- Short bouts — roughly 1–2 minutes per muscle — are plenty. Prolonged, aggressive use risks bruising and offers no extra benefit.
