Massage guns: what they can and cannot do

What the evidence says

Research on percussive devices is still fairly new, and many of the studies are small, short and use different devices and settings. That makes firm conclusions difficult. What the early evidence suggests is broadly similar to what we know about foam rolling.

• Range of movement: a short session can give a small, temporary increase in range, for example at the hamstrings or calves.
• Perceived soreness: people often report feeling less sore after using one, at least for a while.
• Strength and power: short use before training does not appear to reduce performance, but there is no good evidence it improves it either.
• Actual recovery: there is no convincing evidence that it speeds up muscle repair or gets you back to full performance faster.

The likely mechanism is the same as for rolling. Pressure and vibration change how your nervous system perceives the area, so it feels looser and less tender. Nothing is being physically broken down or flushed out. Lactate clears on its own within about an hour of training, and dense connective tissue does not reshape under a vibrating head. Our guide to what foam rolling does and does not do explains this in more detail.

How to use one if you have one

If you already own one or like the feel of it, there is no harm in using it sensibly. The key is gentle, brief and on muscle.

1. Start on the lowest speed with a large, soft or rounded head.
2. Let the gun float over the muscle rather than pressing it in hard. Its own weight is often enough.
3. Keep it moving slowly over the belly of the muscle for about one to two minutes per area.
4. Before training, 30 to 60 seconds on the muscles you are about to use is plenty, followed by your normal warm-up.
5. After training or in the evening, use it for a few minutes if it helps you relax, then stop.

Where not to use it

Massage guns can deliver a lot of force into a small area, so where you use them matters.

• The front and sides of the neck, where major blood vessels and nerves sit close to the surface
• The back of the knee, the groin, the armpit and the inside of the elbow
• Directly over bones, joints and the spine
• Over a fresh injury, bruise, cut, or any area that is swollen, hot or red
• Over varicose veins, or anywhere if you take blood-thinning medication or have had a blood clot, unless your GP says it is fine
• Over areas with reduced feeling, for example from diabetes-related nerve damage
• Over the tummy during pregnancy, or near implanted devices such as a pacemaker

Calf pain with swelling, warmth and redness in one leg can be a blood clot. Do not massage it. Contact NHS 111 or your GP urgently, and call 999 if you also have chest pain or sudden breathlessness.

Massage gun, sports massage or physio?

These are three different things and are easy to confuse. A massage gun is self-applied pressure, useful for feeling looser. A sports massage from a trained therapist is hands-on soft tissue work, often very relaxing, and can help you feel better after a hard block of training. Our guide to physio versus sports massage explains where each fits.

A physiotherapist does something none of the others do: assess what is going on, work out why, and build a plan to fix it. Hands-on treatment can be part of that, and our guide to manual therapy covers what it involves, but exercise and load management usually do most of the work.

If you find yourself reaching for the gun every day for the same spot, that pattern is a signal, not a solution. Lycan Strength has on-site physiotherapy, where the first visit is a full assessment to find the root cause, and gym members get 20% off treatment.

Should you buy one?

If you enjoy the feeling, it makes you more likely to move and warm up properly, and the cost does not stretch you, then a massage gun is a reasonable purchase. Budget models do much the same job as premium ones for most people. You do not need the highest speed, the longest battery life or an app.

If money is limited, it sits well down the list. Good food, decent footwear, a foam roller or even a tennis ball, and above all consistent sleep will do more for your recovery. And if you are buying one hoping it will fix a persistent pain, you would be better spending that money on an assessment.

Keep its role in proportion. A massage gun changes how your muscles feel today. The things that make you more resilient over months, so that you get sore less often in the first place, are progressive training, good sleep and enough protein. No device replaces those.
