Tennis elbow and your racket: a complete guide to equipment that hurts (and how to fix it).

If you're reading this, your elbow probably hurts.

Maybe it started a few weeks ago — a dull ache after long sessions that wouldn't quite go away. Maybe it crept up over months and is now sharp enough that you've stopped playing. Either way, you've likely already tried the standard advice. Rest. Ice. A brace. A note from your hitting partner about your form. Maybe even a doctor's visit that ended with "lay off for six weeks and see how it feels."

Here's what almost no one tells you: the most common cause of tennis elbow in recreational players isn't bad form. It isn't age. It isn't how often you play. It's your equipment.

The racket you swing, the strings you have in it, and the tension they're strung at can mean the difference between an arm that holds up for years and one that breaks down after a few months. And most players are using a setup that quietly works against them — without ever knowing it.

This guide covers the four equipment factors that drive tennis elbow, what each one does to your arm, and what to change. By the end, you'll know exactly what to look at the next time you walk into a pro shop, and what questions to ask your stringer.

We're not going to pretend equipment fixes everything. If you have severe pain, you need to see a doctor — and we'll come back to that at the end. But for the vast majority of recreational players with mild to moderate tennis elbow, the right setup is the difference between getting back on the court next month and being sidelined for the rest of the season.

Why your racket matters more than you think

Every shot you hit is a small collision. The ball arrives at your strings at 40-70 miles per hour, your strings arrive at the ball at 50-80, and the energy of that impact has to go somewhere. Most of it goes back into the ball. But a portion — every single shot, hundreds of times per session — travels up the strings, through the frame, into the handle, and into your hand, wrist, forearm, and elbow.

A well-designed setup absorbs as much of that energy as possible before it reaches your arm. A poorly-designed one passes more of it through. Over hundreds of repetitions in a single session, and thousands across a season, those small differences add up to either an arm that recovers between sessions or one that doesn't.

This is well-documented in sports medicine research. Studies on lateral epicondylitis — the technical name for tennis elbow — consistently identify equipment factors as primary risk drivers, alongside playing volume and stroke mechanics. The frames and strings you choose aren't a minor variable. They're one of the largest levers you have.

There are four equipment factors that determine whether your setup helps your arm or hurts it. In order of impact:

1. Your string type — what your strings are actually made of
2. Your string tension — how tightly they're strung
3. Your racket's stiffness (called RA) — how much the frame flexes on impact
4. Your racket's weight — how heavy the frame is

We're going to walk through each one, in that order. Get these four right and you've eliminated the most common equipment-related causes of tennis elbow. Get even two of the four right and most players see meaningful improvement.

Factor 1: your strings (the biggest cause, and the one most players don't know about)

If you take only one thing from this guide, take this: the type of string in your racket matters more for your arm than the racket itself.

Most recreational players have no idea what's strung in their frame. They bought the racket, the shop strung it with whatever they had on the wall, and they've been playing with it ever since. That's how millions of players end up swinging a setup that's actively working against them.

There are four main string types, and they sit on a spectrum from arm-friendly to arm-aggressive:

• Natural gut is made from cow intestine. It's the softest, most arm-friendly option available, and it's what most pros play. It's also expensive — typically $40+ per string job — and it doesn't last as long as synthetic options.
• Multifilament is made from hundreds of fine synthetic fibers braided together to mimic the feel of natural gut. It's significantly softer than polyester and considerably cheaper than gut. Common examples: Tecnifibre NRG2, Wilson NXT, Babolat Xcel.
• Synthetic gut is a single solid nylon core, sometimes wrapped in an outer layer. It's the most common string in pro shops because it's cheap and durable. Decent comfort, middle-of-the-road on everything else.
• Polyester (often called "poly" or "co-poly") is a stiff, durable monofilament. It's what almost every professional plays — and it's the single most common cause of tennis elbow in recreational players. Common examples: Luxilon ALU Power, Babolat RPM Blast, Solinco Hyper-G.

Why polyester causes so many problems

Polyester is the right string for the right player — at the professional level, where players have flawless technique, restring after every match, and have built up the forearm strength to handle the load. The pros use it because it gives them spin, control, and durability that nothing else can match.

But polyester is stiff. It doesn't stretch and absorb impact the way softer strings do. Every shot transmits more shock to your arm than the same shot would with a multifilament. And here's the part that catches most recreational players: polyester loses its playability fast. After about 10-15 hours of play, polyester goes "dead" — it stiffens further, loses tension, and starts transmitting even more shock. Pros restring before this happens. Recreational players keep playing for months past it.

If you have polyester strings and tennis elbow, this is almost certainly the cause. Not your form. Not your age. Your strings.

What to change

If you have active arm pain, switch to multifilament at your next restring. Tecnifibre NRG2, Wilson NXT, and Babolat Xcel are all excellent and widely available. Expect to pay a few dollars more per string job than polyester. Expect the strings to last about as long as a bag of polyester does once it's gone dead — roughly 20-30 hours of play.

If budget allows and your arm pain is significant, natural gut is the gold standard. Babolat Natural Gut and Wilson Natural Gut are both excellent. Klip Legend is a strong, more affordable option.

If you want some of the spin and control polyester gives you without the full arm stress, there's a middle path: a "hybrid" setup that uses polyester in one direction (the mains) and a softer string in the other (the crosses). Roger Federer plays a hybrid like this. It's not as gentle as a full multifilament, but it's significantly easier on the arm than full poly. Ask your stringer about it.

What you should not do is keep playing through pain on a polyester setup. The strings won't break in. The pain won't go away on its own. The setup is the problem.

Factor 2: your string tension (a free fix most players never make)

The same string can feel completely different at 60 lbs versus 50 lbs. Tension changes how much the stringbed gives on impact — and that "give" is exactly what protects your arm.

Higher tension means a stiffer stringbed. The strings barely move when the ball hits them. You get more control and a more direct feel, but the impact gets transmitted through the frame faster, with more force, and with more vibration reaching your arm.

Lower tension means a softer stringbed. The strings flex more on contact, absorbing more of the impact energy before it can travel up the frame. You get more power and a slightly less precise feel, but the trade-off is significantly less stress on your arm.

Most stringers default to somewhere between 55 and 60 lbs, often because that's where the racket manufacturer prints the recommended range on the throat of the frame. For an arm-sensitive player, that's too high.

What to ask for

For a player with active tennis elbow or significant arm sensitivity, the right range is closer to 45-50 lbs with a multifilament string, and 47-52 lbs with polyester (if you're keeping it). For preventive tuning — players without active pain who want to protect their arm long-term — somewhere in the 50-55 lb range is a good target.

These numbers might sound low if your stringer has been giving you 58 or 60. They are. But the lower end of the manufacturer's recommended range is almost always still inside the safe zone for the frame, and the comfort difference is dramatic.

The next time you bring your racket in to be strung, tell your stringer: "I'd like to drop my tension to 48 lbs to ease arm stress." That's it. Most stringers won't blink — lower tensions for arm-conscious players are a routine request. If yours pushes back, you can stand firm; you're well within reasonable territory.

One thing to keep in mind

Lower tension means more power. Your shots will fly a little longer than they used to for the first session or two. Your spin will feel slightly different. This is normal and you'll adjust to it within a few hours of play. A lot of players who switch to lower tensions never go back — they like the extra depth and the easier-on-the-arm feel.

If you find your shots are flying long even after you've adjusted, you can bump the tension back up by 1-2 lbs at your next restring. The right number is the lowest tension where you still feel in control of your shots. For most arm-sensitive players, that's somewhere between 47 and 50 lbs.

Factor 3: your racket's stiffness (RA)

Every racket has a stiffness rating, called RA. It's a number — usually between 55 and 72 — that tells you how much the frame flexes when it hits the ball. Stiffer frames (high RA) transmit more shock to your arm. Flexier frames (low RA) absorb more of that shock before it ever reaches your hand.

The threshold matters. Frames above RA 66 send measurably more vibration into the arm than frames below RA 62. If you have active tennis elbow, you should be playing something below RA 62. If you're trying to prevent it, RA 65 or below is a safe target.

How to find your racket's RA

Most racket spec sheets include the RA rating, but it's not always front and center. The fastest way to find yours: search "[your racket model] RA rating" or check the spec page on Tennis Warehouse or Tennis Express. Both sites publish RA values for every frame they carry.

If your frame is more than five years old, the published RA might be slightly off — frames soften with use, sometimes by 2-3 points over the life of the racket. A 10-year-old frame originally rated RA 68 might be playing closer to 65 today. This is one of the few cases where an old racket can actually be friendlier on your arm than a new one.

Popular frames and where they sit

Many of the most popular rackets sit on the stiffer end of the scale. The Babolat Pure Drive (RA 71), Wilson Ultra (RA 68), and Yonex EZONE 100 (RA 68) are all best-sellers — and for good reason. They give players easy power and depth without requiring a full swing. But that same stiffness sends more vibration through to the arm on every shot.

If you have active tennis elbow or a history of arm issues, these frames are not the right fit for you right now. That doesn't make them bad rackets. It makes them rackets built for a different player than you currently are.

On the other end of the scale, several manufacturers make frames specifically engineered with arm comfort as a primary design goal. A few worth knowing:

• Wilson Clash 100 (RA 55) — the most flexible frame from a major manufacturer. Wilson built the Clash specifically around the engineering goal of an arm-friendly frame that still played at a high level.
• ProKennex Ki Q+5 (RA 55) — ProKennex has built its entire brand around arm-friendly technology. Less common in pro shops, but a favorite among players recovering from arm injuries.
• HEAD Boom MP (RA 63) — measurably stiffer than the Clash on paper, but plays softer than its RA suggests due to its construction. A good middle-ground option.
• Yonex VCORE Pro / PERCEPT 100 (RA 60) — the PERCEPT line replaced the VCORE Pro and was designed with feel and arm comfort in mind. Strong choice for players who want a more traditional player's frame.
• Wilson Blade 98 v9 (RA 62) — sits just inside the safe zone. Popular with intermediate-to-advanced players who want a control-oriented frame without the arm stress of stiffer power frames.

This isn't an exhaustive list. There are dozens of arm-friendly options across every major manufacturer. The point is that lower-RA frames exist, they're widely available, and you don't have to give up performance to play one.

What to do if you love your current racket

A common situation: a player loves their Pure Drive, has played it for years, and doesn't want to switch — but they're starting to feel arm pain. There are two ways to soften a stiff frame without replacing it.

The first is the strings-and-tension changes we already covered. A Pure Drive strung with multifilament at 48 lbs plays measurably softer than the same frame strung with polyester at 58 lbs. You might not have to change frames at all.

The second is to add a vibration dampener and consider adding lead tape to the handle. A handle-weighted dampener can take the edge off mid-frequency vibration that contributes to arm fatigue. It's not a complete solution for a high-RA frame, but it helps.

If both of those still leave you in pain, then a frame change becomes the right move. But the frame is the most expensive change of the four factors, and we'd rather you exhaust the cheaper fixes first.

Factor 4: frame weight (the counter-intuitive one)

Most players assume a lighter racket is gentler on the arm. It seems logical: less weight to swing, less work for the muscles, less stress on the joint. The reality is more complicated.

Lighter frames vibrate more on impact than heavier ones. When the ball hits the strings, a heavier frame absorbs more of the impact in its own mass before that energy can travel up the handle. A lighter frame has less mass to absorb the shock, so more of it gets transmitted to your arm. The muscles in your forearm and wrist also work harder to stabilize a lighter frame against the force of the ball — which adds another layer of cumulative load over a long session.

Counter to most players' intuition, a frame at 295-310 grams is generally easier on the arm than a frame at 270 grams. Heavier within reason, not lighter, is the arm-friendly direction.

The sweet spot

For most adult players, the comfort range is 295-310 grams unstrung (roughly 310-325 grams strung). This is heavy enough to absorb impact and stable enough that your arm doesn't have to fight the frame, but light enough to swing through long matches without fatigue.

Below 285 grams unstrung, frames start to vibrate more on contact and place more stabilization demand on the forearm. Above 320 grams unstrung, frames are stable but tire most recreational players over the course of a 90-minute session — and a tired arm is an injured arm waiting to happen.

There are exceptions. Older players, players returning from injury, and players with significantly less forearm strength may genuinely need a lighter frame even though the physics favor heavier ones. The key word is "need." If you can comfortably manage a 300-gram frame, you almost always should be playing one.

What to look for

When you check a racket's spec sheet, look for the unstrung weight — sometimes called "static weight" or just "weight." Manufacturers list this prominently. Many players accidentally compare strung weights against unstrung weights and end up with a frame heavier or lighter than they thought.

If you're unsure what your current racket weighs, your local pro shop can put it on a scale in 10 seconds. Or just check the manufacturer's spec page online — every modern racket has its weight listed.

For a player with active arm issues, the practical sweet spot is 300 grams unstrung, head-light balance, with the right strings and tension. Get those three things right and you've handled the four factors that matter most.

The right setup isn't a single answer

Everything we've covered so far is general guidance. It applies to most arm-sensitive players, most of the time. But "most of the time" isn't good enough when you're trying to get back on the court without re-injuring yourself.

The right setup for you specifically — your pain level, your NTRP rating, your play style, your swing speed, your age, your goals — isn't a single racket and a single string at a single tension. It's a combination of all four factors, weighted to your situation.

A 4.5-level baseliner with a fast swing and chronic elbow issues needs a different setup than a 3.0-level doubles player with mild discomfort. Both have tennis elbow. Both need the four factors handled. But the actual numbers — which racket, which string, what tension — are completely different. Generic advice can't bridge that gap.

That's why we built Perfect Racket.

When to see a doctor

Equipment changes can prevent and ease most cases of mild to moderate tennis elbow. They can't diagnose what's actually wrong with your arm, and they can't replace medical care when you need it.

There are five signs that your arm pain is past the equipment-fix stage and into the see-a-professional stage:

• The pain has lasted longer than six weeks despite rest, ice, or equipment changes.
• The pain wakes you up at night or persists when you're not playing.
• You have weakness gripping objects outside of tennis — opening jars, holding a coffee cup, turning a doorknob.
• The pain has spread beyond the elbow itself into the shoulder, wrist, or hand.
• You feel numbness or tingling in your forearm, hand, or fingers.

Any of these warrant a real medical evaluation. Tennis elbow is the common label, but the underlying cause might be something different — a partial tendon tear, a pinched nerve, referred pain from the neck, or an early stage of a condition that requires actual treatment rather than equipment changes. A sports medicine doctor or physical therapist can tell the difference. Online articles cannot.

Even for milder cases, working with a physical therapist alongside the equipment changes we've covered is one of the most effective combinations available. The therapist addresses the muscle imbalances and movement patterns that contributed to the injury; the right equipment stops re-aggravating it. Either intervention alone is good. Both together is dramatically better.

We built Perfect Racket to handle the equipment side of the problem because that's the side most players overlook. The medical side is too important to leave to a quiz on the internet, and we won't pretend otherwise.
