Tennis Forehand Tip: Generate Power From The Ground Up

- Power is generated from the ground up and therefore it all starts with your lower body!
Most club players we see are too focused on the arm action, which messes up the kinetic chain.
In this video OTI Instructor Nadim Naser shows you how to generate more forehand power from the ground up!
Absolutely spot on! When I look at the players at my club hitting, the vast majority are "arming" the ball. I think it is good to mention also turning the hips and then the torso in conjunction with the deep bending of the legs. I think the majority of power comes from the hips and torso rotation, which also causes the much talked about wrist lag (when the arm, wrist and grip is kept loose).
George Oberlander thank you for your feedback. Best wishes
Outstanding Nadim. I love the reference to the subtleness of the kinetic chain on the ATP players! They are so good and so quick and such freakish athletes it is hard to see but the physics are still the same.
Kathryn Egan thank you! Yes, they are freakish indeed and yes the chain is still in tact. Best wishes
Very true most recreational players arm their swings from lack if understanding the exaggeration process does work with some but if they player is naturally a stiff character it is a bit challenging from my experience
Just coming up is not enough, You have to use that to rotate the hips. I was using the legs before but it made me lose balance and fall backwards with the left foot. When I started to rotate the hips deliberately, it fixed the problem
Good video Nadim, one of the best when it comes to loading with legs. I often see videos where some say legs are not that important, or they exaggerate (not only for practice purposes) to really SIT down and RAISE up on all your strokes. Its just important for the player to get a feel of starting the stroke with a PUSH from the ground, depending on the situation and stroke it can be extremely subtle or more pronounced, but it starts the chain that transfers from legs to hips to core to upper body rotation to arm to racquet and makes your stroke fluid and effortless while providing good racquet speed hence power/spin.
Great advice! My kids first coach required hill toe double step on backhand side footwork as must have for weight transfer and solid power kinetic chain!
Mikhail Snitko thank you for your comment. Excellent to hear
good, but MISSING is another MOST IMPORTANT part of Kinetic Chain mechanics that most recreational players are missing: torso coiling and uncoiling. Torso twist. Coil, uncoil. Coil, uncoil. Chin to Chin. Shoulder to Shoulder. Then, "Tap The Dog" (Rick Macci calls it Arm Extention). Most recreational player just "Arm It": swith arm, without any twist of the torso Coiling-Uncoiling (Chin-to-Chin). That is the most difficult part to practice and develop: Coiling-Uncoiling of the torso. I did not find any good exercises, demos, practice routines for this Coiling-Uncoiling of the Torso (Chin-to-Chin) part of Kinetic Chain.
“Sit and come up” is an important element of a tennis stroke. Actually, they are two independent elements.
“Sit” makes your body “wide”. In physics it is increase of the momentum of inertia. To make it even “wider”, place your arms far from your body. When the body is “wide”, rotation of the body created by the player is significant. (Players initiate a counter-clockwise movement, see the clip.)
“Coming up” is actually, stretching the body upwards. This accelerates the rotation. (Simple physics, preservation of an angular momentum, but it works for everybody. The best example is ice-skating.)
…The kinetic chain is a transfer of the angular momentum. It has nothing to do with energy.
Nothing to do with energy?! "Great", wait, I'll just get my coat.
Shmuel Goldberg thanks for your comment. Very interesting insight. Thanks for that
This is true... Kinetics (we talk about a kinetic chain) means movement, not power, not force and not energy. The kinetic chain in this case is transfer of an angular momentum (amount of rotation, actually, momentum of inertia times the speed of rotation.)
So? It has everything to do with energy! Wake up, man. You've been reading too much Kabbalah, not physics. :P
You might be able to explain the tennis stroke using the concept of energy, but it will show only transfer of energy. It will be very difficult to explain acceleration, and especially, how to create acceleration.
Nadim, thanks for another great tip. PS. the mustache works on you.
Yiming Zhang much appreciated :)
Brilliant advice!
Great video coach Nadim! Wondering if you can create a short video on how to properly self toss balls to practice groundstrokes by ourselves (for beginners/early intermediates).
I literally tellmyself sitting in a chair when hitting, or doing a side lunge. powerrrrrrrrful
Oh, this is so gonna mess with my footwork and timing. I now realize that on the forehand side, I am staying on my toes the whole time, and I can see how loading with the heel will result in a much more smooth loading and transfer of weight. The trouble is, if I start stepping in with my heel first, I'd have to change the entire footwork and relearn the timing. It's similar to changing your entire serve motion! How long will it take?
Heel loading...excellent tip !!
You mentioned Lleyton Hewitt "upright and flat" hitting. Would You recommend emulating his forehand, especially his backswing? Seems he usses a lot of rotation force, hitting well inside-out path, with great distance from the ball. I am his height and same age, but I am a club level player around 4.0 level
Great video
XGreat stuff Nadim! Why the importance of heel-to-toe step rather than just a flat step?
Mike Kenny thanks for your comment. If you step with your heel you can truly “load” your weight onto that leg, so that you can unload again, hence use the kinetic chain. Most players who step with the toes, flat or side of their foot first, cannot and do no load properly bust simply shift the weight forward (but not upward as well) or, even more commonly, get stuck in the same spot without any weight transition. Best wishes
It gives you proper weight transfer when you go heal to toe!
Very true!
Game changer
Michael Cannan Cheers my man
Please spend some more time and emphasize loading with the heel.
Selwiyn Thompson I will. Thanks for your comment. Will emphasize in future video even more.

Chandra Vythilingam thanks for your comment. Yes, it is a challenge for many. So much that some coaches don’t advocate using exaggerations. However, once the body is getting used to this “new and more effortless power source” after being exposed to committed training that way, the changes in a player’s game can be truly groundbreaking.
