Start here: a massage gun is not the treatment

How we ranked these, and why amplitude is not on the list

Most massage gun rankings lead with amplitude — stroke length — because it is the spec that decides how deep a percussion device reaches into thick muscle. For this job it is close to irrelevant. The wrist extensor group on the outside of your forearm is a thin sheet of muscle lying over bone, a few centimetres from an inflamed tendon attachment. Nothing about that target rewards a longer stroke, and a long stroke makes it harder to stay off the bone.

Here is what we ranked on instead, in order:

1. Published weight. The dominant constraint, and the one almost nobody mentions. You cannot treat your own forearm with the hand attached to it. You will be holding the gun in your opposite hand, arm crossed over your body, wrist at an awkward angle, for a minute or two at a time. Every ounce is leverage against you. A published 1.5 lb and a published 2.0 lb are different tools in that position.
2. Whether a genuinely low speed exists. Five speeds is not a better spec sheet than three for its own sake; it means the bottom of the range is lower. Beside an irritable tendon you want the gentlest setting the device offers, and a gun whose slowest speed is still brisk is the wrong gun.
3. Head shape, and whether the right one is in the box. The flat and dampener heads are what you want here. A bullet head on a tendon attachment is the single most common self-inflicted injury in this category. More on this below, because it is what people are actually searching for.
4. Size for one-handed control. Related to weight but not identical: a short body is easier to aim precisely at a target the width of two fingers.
5. What the maker publishes at all.The standing rule on this site. We score what manufacturers put in writing and record the absences by name — see cheap vs expensive massage guns for the full table of who publishes what.

The attachment question, which is the real question

Live search for this topic asks about heads almost as often as guns: “best massage gun head for tennis elbow” and “best massage gun attachment for tennis elbow” are both standard completions. That instinct is correct, because head shape changes where the force goes far more than gun choice does.

The practical consequence for the picks: the Theragun Prime ships with two heads, a dampener and a standard ball, and no flat head. The Bob and Brad C2 ships five. If your gun did not come with a flat or dampener head, that is a cheap thing to fix and it matters more than which gun you own.

Where to put the gun, and where not to

The pain is at the bony point on the outside of the elbow. The muscle pulling on it runs from just below that point down the back of the forearm toward the wrist. You work the muscle, not the point.

• Target:the meat of the forearm extensors, roughly a hand’s width below the elbow and continuing toward the wrist. Palm down, forearm relaxed and supported on a table, gun in the other hand, slow passes along the muscle.
• Avoid entirely: the bony prominence itself, and the groove just behind it on the inner side of the elbow where the ulnar nerve sits close to the surface. Percussion over a superficial nerve produces exactly the pins-and-needles you would expect, and it is a reason to stop rather than a sign it is working.
• Dose: a minute or two per pass at the lowest useful speed, light contact pressure, then load the tendon. The gun is the warm-up, not the session.

The picks in detail

Bob and Brad C2 — best overall for a forearm

At a published 1.5 lb this is the lightest full-size gun on this site, and in the reach-across-your-body position that is the difference between finishing a pass and giving up on it. It is also the only gun here whose maker publishes all four depth-relevant figures — a 10 mm amplitude, over 44 lb of stall force, a 2,000-3,200 PPM range and under 60 dB — which we re-read off its product page. Five speeds means a real low setting, and five heads means the flat and dampener you want are in the box. Its cons are honest: 10 mm is genuinely shorter than the stroke premium guns are marketed on, there is no app or pressure screen, and the five speeds are fixed steps rather than a continuous range. None of those three matter on a forearm. Full write-up: our C2 review.

Theragun Relief — when the area is irritable

Therabody built the Relief to be gentler than the rest of its range, and for most of this site’s pages that is a limitation. Here it is the point. A tendon attachment that hurts when you press it does not need the most capable percussion device available; it needs the least aggressive one that still does something. Three speeds, no pressure feedback, no ecosystem. The cons: you are paying a premium brand price for deliberate restraint, and Therabody’s own page does not publish amplitude or stall force, so you cannot compare its reach with anything. If gentleness is what you want, that absence costs you less than usual.

Bob and Brad Q2 Mini — easiest one-handed reach

A pocket-sized gun removes the holding problem almost entirely: your opposite hand is aiming rather than supporting, and precision on a target the width of two fingers improves accordingly. If the forearm is the only thing you intend to treat, this is arguably the mostusable pick on the page. The cons are real if your needs grow: a smaller battery, less headroom on a quad or a glute, and a short body that is less comfortable on large muscle. We compare it against the obvious alternative on Theragun Mini vs Bob and Brad Q2.

RENPHO Active — lowest outlay

The cheapest gun on this site we would still recommend, and for a forearm its lighter duty is barely a constraint — you are not asking it to stall against a glute. The honest reason it sits fourth rather than higher is documentation: RENPHO publishes less about this unit than any other pick here, so there is nothing to check it against. It is a real percussion device rather than a vibrating toy, which is a lower bar than it sounds in this price bracket. See RENPHO Active vs Bob and Brad C2 for the direct comparison.

Theragun Prime — the one to skip here

Not a bad gun; a badly matched one. Everything that earns the Prime its place on the deep-tissue roundup works against it on a forearm: the long stroke Therabody markets it on is aimed at thick muscle, the published 2.0 lb makes it the heaviest thing here to hold across your own body, and its current US product page ships two attachments, neither of which is a flat head. If you already own one, use the dampener, run it slow, and stay well clear of the bony point. If you are buying for this specifically, buy lighter.

What percussion is actually doing here

Worth keeping in proportion. The review of percussive therapy finds short-term range-of-motion and pain-perception effects rather than structural change, and the hamstring range-of-motion study points the same way. For a tendinopathy that is a modest and temporary benefit, which is exactly why the loading callout sits at the top of this page rather than the bottom. If you want the other end of the intervention spectrum, the 2026 network meta-analysis of shockwave therapy in tendinopathy covers a clinic treatment people often confuse with a massage gun; we explain why they are not the same device on massage gun vs shockwave therapy.

Percussion is also not the only symptom-management route here. A TENS unit works on the pain signal rather than on the tissue, and for an elbow protocol handed to you by a clinician the thing that matters is whether the device can be set to the numbers you were given — which is the argument of our TENS 7000 review. Neither route replaces loading the tendon; both can make loading it tolerable.

A fortnight that uses the gun for what it is good at

The failure mode with a massage gun and a tendon is using it instead of the thing that works, usually because percussion feels like treatment and loading feels like exercise. Here is the shape of a two-week block that puts the gun where it belongs. It is a structure rather than a prescription, and anyone who has been given a protocol should follow that one instead.

• Days 1-4, settle it down.Gun on the forearm extensors at the lowest useful speed with the dampener head, a minute or two, once or twice a day. Then light isometric holds — gripping something without moving the wrist — which is the loading style the 2026 isometric review describes as tolerable and short-term analgesic rather than curative. Tolerable is the point this week.
• Days 5-10, start loading. Same warm-up, then controlled eccentric work with the lightest resistance bar: twist with the good hand, let the bad side resist slowly on the way back. Slowly is the whole exercise. The Medicina trial ran 18 supervised sessions across six weeks before measuring, which is a useful calibration for how long this takes.
• Days 11-14, add grip. Once the slow eccentrics are not provoking next-day soreness, grip work goes back in. This is also the point to look at what caused it: a racket grip that is too small, a tool handle you squeeze too hard, a mouse that keeps your wrist extended all day.

Two honest notes on dose. Expect soreness during the loading phase and judge it the next morning rather than during the set; pain that is worse 24 hours later means you went too far. And if two weeks of this produces nothing at all, the answer is an examination rather than a different attachment head — lateral elbow pain has several causes that no amount of percussion will touch.

Is it tennis elbow or golfer’s elbow?

Worth thirty seconds before you buy anything, because it changes which side of the forearm you work. Pain on the outsideof the elbow, worse when you extend the wrist or grip something, is lateral — tennis elbow. Pain on the inside, worse when you flex the wrist, is medial — golfer’s elbow. The gun and head advice above transfers directly; the target moves to the other side of the forearm. We have a separate page for the medial version at tools for golfer’s elbow, and the nerve caution matters more on that side because the ulnar nerve runs behind the inner bony point.

Our read

If you want one sentence: buy the lightest gun with a flat or dampener head and a genuinely slow bottom speed, use it to make the forearm workable, and spend the rest of your money on something that loads the tendon. The C2 is the pick because it is light, documented and ships the right heads. The Relief is the pick if touching the area already hurts. And the honest hierarchy on this page puts a cheap resistance bar above every gun on it — which is an odd thing for a page about massage guns to say, and the reason we think it is worth saying.
