Jen Brady – The Girl Who Rips 3500rpm Forehands

Jen Brady's forehand side by side with Rafa Nadal's forehand, showcasing the similarities through contact.

Jennifer Brady hits her forehand like a man. And that’s a really good thing.

Not just in the sense that Jen Brady’s forehand is awesome, and the forehands on the ATP tour are also awesome. It’s more than that. Jen Brady employs on her forehand specific, efficient, explosive biomechanics that are mostly unique to the male tour.

We’re going to go through and explain these efficient biomechanics as we analyze her beautiful, effective stroke. In doing so, hopefully you’ll be able to implement some of the things she does into your own game.

We’ll also dispel the myth that “female athletes aren’t strong enough” to use these mechanics. As of writing this, Jen Brady is ranked 28 in the world and is about to play in her first major final in the 2021 Australian Open against (3) Naomi Osaka. Win or lose, she’ll be top 20 after the tournament.

Five stages of the Jen Brady forehand depicted as she crushes a short high ball for an inside-in winner
Five key checkpoints in Jennifer Brady’s unique and effective forehand. From left to right they are: the abbreviated backswing, initiation of trunk rotation, passive racket lag, explosive extension and contact, and follow-through.

Jen Brady completely shatters any stereotype about the typical female forehand or female swing. She’s athletic, explosive, and strong. When she gets a short ball on the backhand side, she doesn’t hesitate to run around it and crush a forehand instead, the same way we see Federer doing every tournament.

With her modern game, she crushed college tennis in the United States, and now in this latest Australian Open, she’s on top of the WTA, too. All with a forehand that looks more like Rafael Nadal’s than Serena Williams’s.

So let’s dive in.

Jen’s Abbreviated but Powerful Backswing

One of the keys to the modern forehand’s fault tolerance is its abbreviated backswing. Power in the modern forehand comes from hip and trunk rotation, and it doesn’t take a huge backswing in order to transfer the force generated from the hips and trunk into the racket.

The backswing of the Jen Brady forehand, during which her wrist is relaxed and her hips initiate the swing.
Jen’s racket head only rotates towards her left once she initiates her forward explosion – as she begins her rotation and drives her hips and chest forward, the racket lags behind her hand due to inertia.

The shoulders and hips need to turn away from the target, and then the hitting elbow needs to separate from the trunk, pushing the racket away from the body and preparing for a forward explosion.

That’s it.

Any extra movement of the arm back behind the back, or the racket back behind the back, is extraneous. It’s not necessary to generate power with the hips and trunk.

Extra backswing of the arm or racket hinders fault tolerance, because it increases the time between the initiation of the forward explosion and contact, making it more difficult to time the ball correctly.

Jen Brady’s backswing is quick and compact, but she still gets a beautiful turn of the hips and shoulders away from the target, giving the racket plenty of space to accelerate to blinding speeds through contact. Additionally, by turning her shoulders farther than she turns her hips, she further winds up her rotational kinetic chain, storing even more energy which she’ll unleash as she rotates back during the forward swing.

Importantly, she does this all without adding in additional, extraneous movement of the racket, wrist, or arm – movement which contributes very little to power or spin production, but necessarily decreases the swing’s consistency.

Jen’s Hyper Relaxed Wrist

The wrist acts as a hinge in the modern forehand – it doesn’t generate any force on its own, it merely transfers the force generated by the hips and trunk into the racket. When the rest of the swing is performed correctly, the racket will naturally whip around a relaxed wrist as the trunk rotation flings it around the body.

Hip rotation in the Jen Brady forehand causes her racket to lag behind her relaxed wrist.
Jen’s racket lags behind her hand as she explosively twists her body around, even though she never volitionally sets that wrist lag racket-hand position during the backswing.

To unlock this whipping action, it’s essential that the wrist stay relaxed. Jen keeps her wrist completely relaxed, and as a result the racket head stays on the hitting side of the chest during her preparation. Then, as she explosively twists her hips forward to begin the swing, the racket naturally and automatically lags behind her hand.

She never volitionally pulls her racket into the position we see it in here – all leftward motion by the racket head is caused solely by inertia as her hand is pulled forward, while the racket head, which was at rest during the backswing, attempts to remain at rest and therefore lags behind it.

By the time the racket tip is no longer pointing away from Jen’s body, and is instead pointing at the back wall, Jen has already begun her forward explosion. This position is a dynamic position for her. She’s already forcibly pulling her left arm around and rotating her hips and trunk back towards the target. The new racket position is an automatic result of the beginning of the forward explosion, not a volitionally entered, static position.

The Traditional WTA Backswing

This setup and execution falls in stark contrast to the common technique used on the WTA tour, for example, by Maria Sharapova. Unlike in Jen’s loose-wristed stroke, Maria pre-loads the “wrist lag” position, instead of entering it dynamically as a result of inertia. The racket is being actively pulled back to the non-hitting side of her body in the static position at the end of the backswing, before the forward explosion pulls the hand forward.

Contrasting the Jen Brady forehand, Maria Sharapova pre-loads her wrist, rather than relaxing it in the backswing.
Maria Sharapova cocks her wrist in the backswing and pulls the racket-head behind the body before the hip rotation that initiates the forward swing, preventing it from lagging and snapping around during that swing.

Instead of keeping the racket head on the hitting side of the chest and entering the wrist lag position as an automatic result of the forces generated by the trunk rotation, Maria’s racket starts in that position, because she puts it there during her backswing. This adds unnecessary tension to the wrist and prevents the inertia driven lag and snap from occurring.

This difference in preparation is one of the primary reasons why Jen Brady’s stroke can generate so much topspin, while Maria Sharapova’s cannot. Jen’s wrist functions as a hinge that transfers the force generated by her trunk into the racket, whipping it around her hand.

Maria’s wrist, on the other hand, does not function as a hinge. Since she locks it in place during the backswing, rather than keeping it completely relaxed, there’s very little of the inertial racket lag and snap action that Jen’s racket performs.

Maria Sharapova, still hits really, really hard, because her hip rotation is still explosive. Additionally, her swings are still relatively fault tolerant, because she does adhere to the fundamental theorem of tennis, but she’ll never be able to create the upward racket trajectory through the ball necessary to rip a 3500rpm winner the way Jen can, because doing so requires allowing the racket to whip around a loose, relaxed wrist through contact.

Jen’s Explosive Hip Rotation

To be fair to the other women on tour, they all get this part right. All women on tour use their hips to generate a substantial amount of power on their forehand. However, the timing of that powerful hip twist differs between women.

Though all elite forehands use explosive hip rotation to generate racket head speed, for Jen Brady the hips are even more essential, because she isn’t using any sort of extended backswing or pendulum effect to create power. She’s focusing solely on her prime movers to generate force – the hips and trunk.

Jen Brady (left) initiates her forward swing by explosively rotating her hips and shoulders forward, while Maria Sharapova (right) injects power with the hips later, initiating her swing by pulling her arm forward with her chest.

By the time her racket is being pulled forward into the forward swing, she’s already unloaded all of the potential energy stored in her hips into it. Her rotational explosion is essentially complete, and all that’s left is for her racket, which is now screaming forward and flicking around her relaxed wrist at a blistering place, to smack through the ball and then decelerate.

This, again, falls in contrast to a traditional WTA forehand, during which the arm is pulled forward first by the chest, while the hips remain turned away from the target. Speed from hip rotation is injected later in the swing, (it is eventually injected, as it must be to produce an elite forehand), but there’s a stark difference in the way the rotational kinetic chain is being harnessed. For Maria, the racket is already coming forward as the hips just being to unlock, whereas for Jen, the racket is driven forward by that hip rotation, and by the time her arm reaches the position depicted above, her rotational acceleration is essentially complete – her hips and trunk have been fully twisted back towards the net.

Jen’s Extension Through Contact

By contact, Jen has already whipped her hips and chest around, unloading all the force that was previously loaded into her core during her unit turn. Her left hand has been forcibly pulled out and back to the left side of her body, helping her twist her chest around.

Contact during the Jen Brady forehand; the elbow is away from and in front of the body, leading to fault tolerant contact.
By contact, Jen’s hips and chest have fully rotated back towards the target, and the speed from that rotation has been successfully transferred into the racket.

Her racket is whipping through the ball well in front of her body, and we can see that her elbow is separated from and in front of her chest. This space between the elbow and chest allows the arm to whip around the trunk unimpeded as it rotates.

The forward extension through the shot is the final ingredient Jen uses to create fault tolerance in her modern stroke. It signifies a successful transition from the rotational force of the hips and trunk, into the front-back transnational force that will ultimately drive the ball back over the net. Extending through the contact point like this creates a long hitting zone; it gives the player marginally more time during which correct, clean contact with the ball can be made.

On this particular short forehand, she’s employed a footwork pattern very often used on approach shots by the great Roger Federer, where she drives so hard off of her hitting foot that it comes up off the ground and then naturally kicks back behind her other leg to counter-balance her vigorous upper body rotation.

Like all great forehand strikers, male or female, Jen’s head is stable and her eyes are glued to the contact point, where they’ll remain until the ball has left the strings.

Jen’s Racket-Over Follow-Through

Follow-throught of the Jen Brady forehand; her racket has extended far in front of her body, and her strings have naturally turned over.

Jen’s racket naturally turns over as part of her follow-through because of the way she swings through contact. This follow-through is NOT volitional, and a player should NEVER consciously try to turn their racket over as they swing. This turn happens naturally as a result of the relaxed wrist and body rotation during the forward explosion.

The follow through doesn’t actually matter, per se, because it transpires after the ball is already gone. We discuss it and evaluate it only because it gives us clues as to what happened during the hitting phase.

Jen’s follow-through displays great forward extension of the arm away from the body, indicating that she’s successfully transferred the rotational force from her trunk into front-back transnational force through the ball.

We also see that her strings have turned over, which is the natural way that the racket decelerates itself after whipping around the wrist through the hitting zone (though the string angle is constant during that whip). This indicates that she is correctly relaxing her wrist and allowing it to be thrown out to the ball as she rotates.

The Common WTA Follow-Through

Contrasting the Jen Brady forehand, Maria Sharapova's strings don't turn over, because her racket never whipped around her wrist due to her backswing.
Maria Sharapova’s wrist ends in the same relative position it started in, indicating that it wasn’t used as a hinge to transfer force and generate topspin.

Again, Jen’s follow-through position is very different from that of a traditional WTA forehand user like Maria Sharapova. Because the racket whips around Jen’s hand during her swing, it naturally turns over as the swing completes.

Since Maria’s racket, on the other hand, does not whip around her wrist at all, at the completion of her swing the racket-wrist angle is almost the same as it was at the back of the backswing. The racket doesn’t turn over, because there’s no momentum encouraging it to.

It’s important to point out here that if Maria wanted to imitate Jen’s stroke in an attempt to generate the topspin that Jen generates, consciously trying to turn her racket over in her follow-through would NOT work and would be wholly and completely counterproductive. Rather, if Maria wanted to hit a heavy ball by utilizing a whipping wrist action like Jen, she would have to load her racket differently – taking the racket back on the hitting side of the body with the wrist totally relaxed, and then allowing the wrist to lag and flip as she leads her swing with her hip and trunk rotation, rather than by pulling with her arm.

The Next Generation of WTA Forehands

We’re already seeing Jennifer Brady’s “male” forehand mechanics taking over the women’s tour. To start, Justin Henin and Sam Stosur proved that women could take advantage of all the same biomechanical advantages that the men could. They proved that an abbreviated backswing with a relaxed, whipping wrist was just as effective for the girls as for the boys, and since their innovation, many more young female players have followed suit.

Naomi Osaka, Ashleigh Barty, and Iga Swiatek are just a couple of young, dominant players who have significantly shorter backswings and more relaxed wrists than their older, more traditional counterparts.

As a result, topspin and fault tolerant strokes are taking over the WTA. It’s an absolute pleasure to watch Jen Brady forgo playing a neutral, rally backhand out of her backhand corner, and instead sprint around a floaty ball to her left and crush a 3500rpm inside-out forehand to win the point.

    It’s noticeable and interesting how her hitting arm and elbow position is very bent vs Rafa and Fed with a straight arm. Djokovic and Nick Kyrgios (most tour players) also demonstrate a significantly bent elbow position throughout the stroke. I’m assuming this is a feature of a more western grip structure. The elbow seems to point to the ground during the swing. With the Eastern grip, it seems the elbow gets extended, arm goes straight.

    It seems easier to rotate the racket around the forearm with a western grip. In the book you mention grip is a “red herring” however there seems to be a correlation between grips and ball spin rotation. Is there a different swing vector in the out direction between an Eastern and western grips?

    Because I can’t lay my wrist back very much, I’m wondering if I should commit to learning a Western grip. I’m currently more Eastern and when I try to swing in the out vector fast, my wrist goes to neutral as my arm straightens and I get stuck with almost 180degree arm racket position. Am I doing something wrong with my swing or is my wrist too weak and stiff to be using a strong Eastern/mild semi western grip? I hardly get any whoosh on my swing and can’t figure out why even if I stay relaxed and breath out.

      Seems like you’re quite the academic (like myself). If you want to explore the ins and outs and biomechanics of all the different forehands on the tour, by all means, go for it. It’s a lot of fun. That said, with respect to improving your own game (rather than studying simply as an academic exercise), focus on the essentials of the movement, not on the joint angles and limb positions:
      1. The hips and abs drive the racket, not the forearm and hand.
      2. The forehand is a twisting motion
      3. The hand needs to stay relaxed for the wrist to effectively transfer force
      4. In order for the relaxed swing to work, contact needs to happen away from your center: both laterally away and in front of you

      The grips and their related elbow bends are all just ways that players accomplish the same few fundamental goals of the forehand. Some players (myself included) even play certain forehands with a straight elbow, and others with bent elbows.

      When I want to hit a swinging volley flat, I usually use a pretty heavy elbow bend. Why? No idea (actually I do know why, but if I weren’t a coach I wouldn’t). All I’m doing is visualizing how I want to strike the ball, then violently twisting my abdominal muscles and tracking the ball all the way into contact in front of me, while keeping my hand and wrist relaxed.

      If you’re really struggling to get any sort of whip, you can send a clip of yourself doing shadow swings to faulttoleranttennis@gmail.com, and I can take a look at it. Fault Tolerant Tennis is still a new brand, so you’re lucky we’re still offering this kind of personalized advice for free 😉

      Here’s my best educated guess: Reread “Unit Turn, Unit Swing” on Page 90. Many players who can’t get the whip have one of two issues. Either they fire their chest too early, bringing their right arm forward before their chest rotates, or they don’t keep their chest stable enough, and while the abs twist forward, the right arm lags behind. Using the entire upper body in sync is really the key that unlocks the loose forward flick action that’s so effective.

        Thank you both for your great explanations. As a Medical Doctor, I see that what one calls “relaxed wrist” implies, in fact, relaxed arm and shoulder. The turn, the whipping effect, does not come from the hand turning around the forearm – in other words, it it not a “wrist articulation slap” and it does not come solely from the forearm turning around the arm – while it is an important component of the turn – but it implies that the arm itself turns around the torso (at the shoulder level),. So, “relax your hand or relax your wrist”really mean “relax all your arm and shoulder and let all articulations turn freely to generate the snap effect”. I think we see this in the Carlitto Alcaraz swing. What do you think?

          For different players, the rotation comes from different places. For an Eastern grip player like Federer, there is a lot of rotation right at the hand, and less at the shoulder, whereas for a western grip player like Jen Brady, it’s much more shoulder driven rotation.

          This is an important insight; I’m glad you picked up on it. The wrist, forearm, and shoulder all contribute, and all must be loose enough to move freely. “Let all articulations turn freely” is a great way to phrase it.

          Carlos uses a semi-western, the grip that most use, because it gives you the best of both worlds. You can activate both your hand/wrist rotation and your internal shoulder rotation with ease. As far as studying the optimal way to hit a forehand, Carlos Alcaraz is certainly a great start.

    Really appreciate this followup, guidance and support, will definitely send you some video. 🙏

    Like you, I really enjoy studying and learning, both academic and applied 🧠

    I’ll focus on the 4 points you’ve recommended, keeping the hand and forearm relaxed is truly a challenge 🥴

    Re reading page 90 is in progress! 🤓 It’s so helpful to understand why and how key movements need to be done to power the stroke, the cause and effect sequence.

    I’ll followup further by email, again, thanks for all the helpful replies and support, and putting out the awesome book. 📖
