Amplitude: buzz vs thump

Amplitude is how far the head physically travels each stroke. 10mm and under feels like vibration — pleasant on skin, shallow in effect. 12mm is the credible middle. 14–16mm is the deep 'thump' that actually moves muscle tissue — what physical therapists reach for. If a listing hides amplitude, assume 10mm or less; that omission is the tell.

Stall force: the pressure budget

Stall force is how hard you can lean in before the motor stops. 30lbs quits under moderate pressure on a quad; 40–60lbs holds up to real use. Pair the two specs: 14mm+ amplitude with 40lb+ stall force is a genuine percussion tool; 10mm with 25lbs is a relaxing buzzer — fine, if that's what you're buying on purpose.

Mini guns: honest role

Minis trade amplitude and stall force for a bag-friendly size — most run 7–10mm. As travel/desk devices for tension and warm-ups they're great; as recovery tools for a leg day they're underpowered. One good full-size beats a full-size-plus-mini bundle for most people.

Using it without hurting yourself

Float the gun and let amplitude do the work — grinding it in defeats the mechanism and bruises. 30–60 seconds per muscle group, keep it moving, muscle only: never bone, joints, the neck's front, or anywhere numb or acutely injured. Before workouts it wakes muscle up; after, it takes the edge off soreness. It's a recovery aid, not a repair shop — persistent pain belongs to a professional.

Key takeaways

• Amplitude decides depth: 14–16mm thumps muscle, ≤10mm buzzes skin.
• Stall force 40lb+ means it works when you lean in.
• A hidden amplitude spec almost always means a low one.
• Float it, keep it moving, muscle only — 30–60s per group.

FAQ

What amplitude should a massage gun have?

For genuine deep-tissue effect, 12mm minimum and ideally 14–16mm. Under 10mm is vibration therapy — relaxing, but a different product.

Are cheap massage guns worth it?

Just don't expect leg-day recovery from 8mm of travel — match the tool to the job.

How often should you use a massage gun?

Daily is fine — 30–60 seconds per muscle group, floating pressure. More isn't better; bruised tissue recovers slower.

Where should you never use one?

Bone, joints, the front/sides of the neck, varicose veins, numb areas, and acute injuries. Muscle belly only.
