Ekrin Athletics B37
Mid-budget done right. 12mm amplitude, 56 lb stall force, 8-hour battery, lifetime warranty. The value pick when Theragun is out of budget.
Gym Score breakdown
Composite of build quality, durability, value, performance, and owner satisfaction. Calibrated per category.
- Buyers who value a lifetime warranty over flashy specs
- Daily users who want long battery life (8 hours per charge)
- First-time massage gun owners not sure they will stick with it
- Recreational lifters who do not train hypertrophied tissue daily
- Travel use where a long battery between charges matters
- You need 16mm amplitude for deep work on dense muscle
- You have a pacemaker or unmanaged cardiovascular condition without physician clearance
- You are pregnant and have not consulted your OB
- You want a polished mobile app experience
Storage only. Hard case roughly 11 by 8 by 3 inches.
none — Charge fully on arrival, attach a head, run. 4 attachments in the case.
Recovery use post-training. The lower amplitude makes it well-suited as a quick warm-up primer too, since you are unlikely to over-target small muscles.

- + 8-hour battery
- + 56 lb stall force
- + Under $230
Weaknesses

What owners actually complain about
Synthesized from owner reviews and community threads. Paraphrased, not quoted.
- 12mm amplitude is the main spec ceiling on dense muscle
- Heavier than premium guns at the same price point
- App functionality is limited compared to Therabody or Hyperice
- Default attachment set is smaller than Achedaway's
- Stall force advertised at 56 lb but feels closer to 40 lb under real load
The warranty play
The Ekrin B37's pitch is simple: lifetime warranty, long battery, reasonable specs, under $230. Most massage guns carry a one-year warranty. Ekrin's lifetime coverage genuinely covers motor failure, gear failure, and battery degradation. That is a real differentiator in a category where battery loss is the dominant failure mode.
What you give up
12mm amplitude is the main spec compromise. Theragun Prime and Achedaway Pro both run 16mm at similar or lower price points. On dense tissue this is felt as a surface-level buzz rather than a deeper punch.
The app is rudimentary. The hardware works fine without it, but if you wanted guided sessions, Therabody's experience is in a different league.
Weight is on the higher end of the category. After a long upper-back session, your wrist feels it more than with a Hypervolt 2.
What you get
A reliable workhorse that the company will replace if it fails. 8 hours of battery on lower speeds, 3 to 4 on the top setting. 56 lb of advertised stall force, though Garage Gym Reviews' measured numbers suggest the practical ceiling is closer to 40 lb. Either way, more than enough for any non-therapist user.
Four attachments cover the standard cases: ball, dampener, fork, thumb. The case is sturdy and travel-friendly.
Who should buy it
First-time massage gun owners who are not sure they will use it three years from now. The lifetime warranty effectively eliminates buyer regret. Recreational lifters who do not train hypertrophied tissue. Frequent travelers who want fewer charging stops.
Who should not: lifters with developed glutes and lats who want the deepest amplitude available. The 12mm number will feel short for that use case.
On daily-use considerations
The NIH research on percussive therapy applies to all guns in the category equally. 60 to 120 seconds per muscle group, avoid acute injury sites, do not press over bony landmarks. The Mayo Clinic notes that DOMS resolves on its own in 24 to 72 hours, and any massage tool is a comfort intervention.
The Ekrin B37 is a comfort tool with insurance. For most buyers that is the right combination.
Long-term verdict
We rank the Ekrin B37 fourth in this category because three guns above it offer meaningful spec or design advantages: the Theragun Prime's triangle handle and ecosystem, the Hypervolt 2's noise floor, the Achedaway Pro's raw specs per dollar. But the lifetime warranty is a real value, and if those other guns' advantages do not matter to you, the B37 will outlast them all.
