The ekrin b37 for bartenders with shaker elbow is one of the most practical recovery tools you can keep in your bar kit in 2026, because it pairs a 15mm amplitude stroke with a low-stall, brushless motor that can actually reach the deep extensor tendons running from your lateral epicondyle down to your wrist. Bartenders who shake 80 to 200 drinks a night develop a very specific overuse pattern: inflamed common extensor tendon at the outer elbow, irritated extensor carpi radialis brevis, tight forearm flexors from gripping the tin, and trigger points in the brachioradialis. The Ekrin B37 handles this pattern well at 35 to 56 lb of stall force across five speeds, with a 15-degree angled handle that keeps your wrist neutral while you self-treat after service. Below we cover exactly how to use it for shaker elbow, where it falls short, and which alternative percussion guns are worth considering if you want heat, cold, or higher intensity.
Why bartenders specifically get "shaker elbow"
Top Picks
Shaker elbow is the bar industry's nickname for lateral epicondylitis, the same overuse tendinopathy that tennis players get from repeated wrist extension under load. Shaking a Boston tin loaded with ice and liquid is essentially a 12 to 18 ounce dumbbell that you whip through 30 to 60 reps per cocktail, often with your wrist cocked into extension and your forearm pronated. Multiply that by a 250-cover Friday and you have the perfect mechanical setup for micro-tearing in the extensor tendon origin at the outer elbow.
Finding the right ekrin b37 for bartenders with shaker elbow comes down to matching watt-hours to your actual power needs.

The companion injuries are just as predictable. Bartenders develop De Quervain's tenosynovitis along the thumb side of the wrist from twisting cap openers and citrus, ulnar-side wrist pain from heavy ice scoops, and chronic forearm hypertonicity that radiates up into the elbow. A percussion massager addresses all four of those tissues if you use it correctly. The ekrin b37 for bartenders with shaker elbow works because it gives you enough amplitude to reach the deep forearm muscles without the harshness of a higher-end Hypervolt or Theragun Pro on already-inflamed tissue.
How the Ekrin B37 stacks up for bar-shift recovery
The B37 is the original 2.5 lb model with a 15-degree handle, 15mm amplitude, 56 lb stall force, and roughly 6 hours of battery on a single charge. For a bartender that translates into about a week of post-shift recovery sessions without scrambling for a charger before doubles. It ships with four heads: a flat for general extensor sweeps, a bullet for the lateral epicondyle and brachioradialis trigger points, a fork for sliding along the radius and ulna, and a round for the broader forearm bellies. The lifetime warranty is also legitimately useful in an industry where you drop gear on tile floors.
Where it falls short: no heat, no cold, no app, and the 56 lb stall is not enough if you are also a powerlifter or do heavy strength work on your off days. For pure bartender use it is plenty, but the alternatives below are worth a look if you want adjunct therapy.
Comparison: Ekrin B37 vs. the best alternatives for bartender wrist and elbow pain
| Model | Weight | Amplitude | Stall Force | Heat / Cold | Best for shaker elbow when... |
|---|---|---|---|---|---|
| Ekrin B37 | 2.5 lb | 15 mm | 56 lb | No | You want a quiet, reliable, lifetime-warrantied bar-kit gun |
| RENPHO Active Thermacool 2 | 1.8 lb | 10 mm | ~30 lb | Yes (both) | Acute flare-up needs cryotherapy plus percussion |
| TOLOCO Massage Gun | 2.2 lb | 12 mm | ~40 lb | No | You want a budget backup for the bar bag |
| AERLANG Heat Gun | 2.4 lb | 10 mm | ~35 lb | Heat only | Pre-shift warm-up of cold forearms |
| Medcursor High-Intensity | 2.3 lb | 12 mm | ~50 lb | No | You also lift heavy on off days |
| NAPRE Heat + Cold | 2.0 lb | 10 mm | ~30 lb | Yes (both) | Daily contrast therapy on chronic tendinopathy |
The protocol: how to actually use the Ekrin B37 for shaker elbow
Most bartenders use a massage gun wrong on the elbow. They jam the bullet head directly into the bony point of the lateral epicondyle, which is where the tendon inserts and where it is already inflamed. That makes it worse. The correct sequence for the ekrin b37 for bartenders with shaker elbow is to work upstream and downstream of the tendon, not on it.
- Warm the forearm first (60 sec). Flat head, speed 1, glide from elbow crease to wrist on the extensor side (top of forearm). Do not press in. You are warming, not treating.
- Forearm extensors (90 sec). Flat head, speed 2-3, slow sweeps along the back of the forearm. Pause on any tender knot for 15 seconds maximum.
- Brachioradialis (60 sec). Round head, speed 2, on the thumb-side ridge of the forearm just below the elbow. This is the muscle that does most of the shaker work and is almost always locked up.
- Around (not on) the lateral epicondyle (60 sec). Bullet head, speed 1, work the tendon two finger-widths below the bony point. Never directly on the bone or insertion.
- Flexors (60 sec). Flip your arm over. Flat head, speed 2, palm-side forearm from elbow crease to wrist. Releasing the flexors reduces tension on the extensor side.
- Finish with passive wrist stretch. Arm straight, palm down, gently pull fingers toward floor for 30 seconds each side. The gun loosens the tissue; the stretch restores length.
Total time: about 7 minutes after a shift. Do this five nights a week and most cases of shaker elbow improve within 3 to 4 weeks. If you are not seeing progress in 6 weeks, see a sports physio for an ultrasound — you may have a partial tear that needs eccentric loading rehab rather than soft tissue work.
Alternative picks worth keeping in your bar bag
RENPHO Active Thermacool 2 — best when shaker elbow is acutely flared
If you finish a Saturday double and your outer elbow is hot, swollen, and pulsing, percussion alone will aggravate it. The RENPHO Active Thermacool 2 alternates between a heated head and a Peltier-chilled head, letting you contrast-treat the joint in the same session. Cold first to calm the inflamed tendon, then percussion at low speed on the surrounding muscle, then heat to flush the area. It is lighter than the B37 at 1.8 lb and easier to one-hand on your own elbow. Stall force is lower, so it is not the gun you want for thick muscle groups, but for a wrist and elbow protocol it is excellent. RENPHO Active Thermacool 2 Massage Gun with Heat and Cold.
TOLOCO Massage Gun — best budget backup
The TOLOCO is the gun every working bartender we know already owns or has borrowed. It is not as refined as the Ekrin and the head attachments fall out if you drop it, but at its price point it delivers usable percussion for forearm and shoulder recovery. Keep one in the bar's break room as a shared kit gun while the B37 lives at home. Twenty speeds is overkill — you will use three of them — but the included carry case is genuinely durable. TOLOCO Massage Gun.
AERLANG Massage Gun with Heat — best pre-shift warm-up
Cold forearms and a cold elbow tendon walking into a Friday night are an injury waiting to happen. The AERLANG has a heated head that pre-warms the tissue before you start shaking. Five minutes of low-speed heated percussion across the forearm before the rush is a small ritual that pays back in fewer flare-ups. Stall force is modest, but for warm-up that is exactly what you want — you are not trying to release adhesions, you are raising tissue temperature.

Medcursor High-Intensity Brushless — best if you also lift
Bartenders who train hard on off-days need a gun that can also handle quads, glutes, and lats. The Medcursor brushless motor delivers higher stall force than the B37, which matters on dense muscle. The trade-off is more vibration in the handle, which is less pleasant for delicate forearm work. If you can only own one gun and your training matters as much as your bar shifts, this is a defensible pick. Just dial speed down to 1 or 2 when treating the elbow. Medcursor Massage Gun.
NAPRE Massage Gun with Heat and Cold — best for chronic tendinopathy
If your shaker elbow has been with you for over six months, you are dealing with a chronic tendinopathy rather than an acute strain. The treatment for that is daily contrast — alternating heat and cold to drive blood flow and reorganize collagen. The NAPRE makes this convenient in a single device, so you are not juggling ice packs and heating pads behind the bar. Use cold on the lateral epicondyle for 90 seconds, heat for 90 seconds, percussion around the area for 2 minutes, then repeat the cycle once. Massage Gun with Heat and Cold.
Workplace fixes that multiply the gun's effect
Percussion therapy works much better when you also fix the mechanics that are creating the injury in the first place. A few high-leverage changes:
- Switch to a lighter shaker tin. Heavy weighted tins look pro but tax the extensor tendon harder. Go to a standard 28 oz tin during a flare-up.
- Shake with a neutral wrist. The classic over-the-shoulder shake locks the wrist into extension. Try a horizontal Cuban roll or Japanese hard shake variant that keeps the wrist straighter.
- Switch hands every other drink. Even partial ambidexterity halves the load on your dominant side.
- Use a counter-pressure wrist sleeve during shifts. A 3mm neoprene sleeve with a forearm strap below the elbow redistributes load away from the inflamed tendon insertion.
- Eccentric loading 3x per week. Tyler Twist with a FlexBar is the gold standard rehab for lateral epicondylitis. The percussion gun loosens tissue, but the eccentric work is what actually rebuilds the tendon.

What to look for in a massage gun if you work behind a bar
Bartenders have unique needs that change the buying criteria. A few things to prioritize:
- Quiet operation (under 55 dB). You will use this in the staff room between shifts. A loud gun is a gun you will not actually pull out.
- Battery life over 4 hours. You will not remember to charge it nightly. Six hours is the sweet spot.
- Angled handle. The 15-degree handle on the B37 keeps your wrist neutral while you self-treat, which matters when the wrist itself is the injured joint.
- Bullet and fork heads included. These are the two heads that do the actual work on forearm tendons. A gun that ships only with a flat ball is half-useless for this use case.
- Sub-3 lb weight. Heavier guns are fine for treating someone else's quads, but you cannot one-hand a 3.5 lb gun on your own arm for 7 minutes without your shoulder cramping.
Frequently Asked Questions
Is the Ekrin B37 strong enough for severe shaker elbow pain?
For soft tissue treatment around the elbow, yes — 56 lb of stall force is more than enough for forearm extensors, brachioradialis, and surrounding muscles. Severity of shaker elbow is not solved by more force; it is solved by avoiding the inflamed tendon insertion entirely and treating upstream and downstream tissue. If your pain is severe enough that gentle percussion is unbearable, you likely need a sports physio assessment rather than a stronger gun.
How often should bartenders use a percussion massage gun on the forearm?
Five to seven times per week during an active flare-up, for 5 to 8 minutes per session, post-shift. Once the pain is gone, drop to 3 sessions per week as maintenance. Daily use indefinitely is fine as long as you keep the speed moderate and avoid hammering the same trigger point for more than 15 seconds at a time.
Can a massage gun make tennis elbow or shaker elbow worse?
Yes, if you use it incorrectly. The two mistakes that aggravate the condition are pressing the bullet head directly onto the bony lateral epicondyle (where the tendon attaches and is already inflamed), and using maximum speed on acutely swollen tissue. Always treat the muscle bellies upstream and downstream, not the tendon insertion, and start at speed 1 to gauge tolerance.
What is the difference between the Ekrin B37 and the Ekrin B37S for wrist pain?
The B37S is the smaller, quieter version at 1.1 lb with 10mm amplitude and 35 lb stall force. For wrist and small-joint work it is actually more comfortable to maneuver than the full B37. The trade-off is less reach into deep forearm muscle. If your problem is purely wrist (De Quervain's, ulnar-side pain) the B37S is the better pick; if it is forearm and elbow combined, the B37 wins.
Should I use heat or cold on shaker elbow after a shift?
Cold for the first 48 hours of any new flare-up to calm acute inflammation, then switch to heat or alternating contrast therapy for chronic management. A device like the RENPHO Active Thermacool 2 or NAPRE gun lets you do this without juggling ice packs behind the bar. Percussion alone is fine for chronic tightness but does not address acute inflammation as well as ice does.
How long does it take to recover from shaker elbow with daily percussion therapy?
Mild cases respond within 2 to 4 weeks of daily massage gun work, eccentric loading exercises, and shake mechanic changes. Moderate cases take 6 to 12 weeks. Chronic cases that have been ongoing for over a year often need 3 to 6 months plus a structured rehab program. Percussion is one input — it does not replace eccentric loading or workload modification.
Can I claim a massage gun as a work expense as a bartender?
In most U.S. tax jurisdictions, recovery equipment used to maintain your ability to perform your job can be deducted as a work-related expense if you itemize, particularly if you are a 1099 contract bartender or own your bar. W-2 employees have limited deductions post-2018 federally but should check state rules. Talk to a CPA familiar with hospitality workers.
Is the Ekrin B37 worth it compared to a $40 Amazon gun for bartenders?
For working bartenders who shake 5+ nights a week, yes. The quieter motor, longer battery, lifetime warranty, and angled handle add up over months of nightly use. For an occasional home bartender doing 3 cocktails on a Friday, a budget option like the TOLOCO will do the job. The decision comes down to how many shake-reps your tendons actually absorb per week.
