Simple Tip To Improve Your Serve I TENNIS SERVE

[@ALEXTHETRUCKINGGUY]

I just want to say thank you. Because of you my entire life has changed. I dedicated my life to being the best tennis player I could possibly be and eventually got a tennis scholarship. At times I trained 6hrs/day. I was placed last on my tennis team for years, but I just kept believing in the vision I had for myself and not the vision others had on me. If it weren't for your channel I would have never gotten that tennis scholarship and I would have never gained the character I have today. I could say thank you a thousand times and that still wouldn't express the gratitude I have but here's one anyway: THANK YOU.

[@TennisEvolution]

Thank you very much Alex. I appreciate your kind words, you left me speechless . I want to acknowledge your commitment and passion for our sport. Keep up the same growth mindset on and off the court! Jeff.

Dear Jeff, this lesson was the best I saw for years for the serve. Thank you so much. I think in all strokes the first move is so important. But most important for the serve. You are great. The you Tube Award is yours!

Thanks, this was a great help, I tried the platform stance, and it helped me time my serves better, took less effort to generate pace and I'm convinced that it will help me be more consistent in matches. My coach taught me the pinpoint stance and thinking back it just was not the right stance for me and led to a lot of foot faults along the way.

Jeff, I appreciate you making this video. I was up 40 love in my GCTA (Greater Columbus Tennis Association) doubles match last week and wound up getting broken. I lost sleep over that and I am committed to making sure it won't happen again. As a shorter player I find that following your serve tips has helped my serve greatly. I finally stopped doing "down together up together" but I still have a long way to go. Since I don't have the stature to give me a boost I have to ensure that my technique is even more efficient.

Thank you Marc! The stance is one of the fundamental components for building a great tennis serve. Keep up the great effort.

[@oceancrossing]

I want to thank you for this video. So I watched this yesterday and tested this out this morning. It fixes a few things. 1. Bend my legs and leap. I wasn’t able to do that consistently 2. Complete pronation. With the body facing the service line I wasn’t able to pronate naturally. In fact it felt awkward. Now the pronation feels natural 3. Bigger kick 4. Increased speed now that i turn my body 5. For some reason I cannot explain, my toss is now much more consistent than before So thank you for showing me this. 👍🙏👍🙏

[@tommycartwright]

Thanks Jeff, the toughest thing I find with this stance is coordinating the "uncoiling" motion that is required to eventually hit the ball after it's been tossed in the air. There's quite a range of motion to cover in order to finally get there and smack it!

[@TennisEvolution]

You’re welcome, thank you for watching.

Great tip. I have a good turn now, thanks to your earlier videos. Most of your lessons talk about the backward turn to coil and load up. Please say a little more about the forward turn as you go into the serve motion.

[@Phoniq]

Ok so I tried it today and I've gotta say it does make a difference. Just got to keep working on it to get the body used to the feeling and make some slight foot adjustments but it definitely helped open me up. I videoed the session and also noticed I was doing some weird thing with my ball toss so I'll tweak that and see if that effects the whole sequence. Ah the serve!

[@geoffhess2267]

Jeff, needed to comment on this. I tried this yesterday during my doubles match. Results were impressive. Prior to trying it, I was sure that it would be great for the kick serve, but not sure how it would work for slice and flat. It worked well not only for kick, but I experienced more power and was still able to hit my flat and slice serve. However, my lower back was pretty fatigued post match. I suspect it was due to the more extreme rotational effect coming into play at the hips when hitting a flat and slice serve. Am I wrong? I subsequently viewed your video "Should You Change Your Serve Stance" in which you encourage experimenting with the stance for slice vs. kick. That makes so much sense to me. We all differ in our flexibility, core strength, and other physical factors that are a function of genetics, our daily routine, and age, (some of which can be corrected and some of which we just need to deal with). I encourage everyone viewing this video to check out your other valuable video as well. Thank you so much for your unique and valuable expertise that you're sharing to allow us committed competitive tennis players to reach that next level!

[@mharlen03]

Is the stance the same on the deuce side for a righty (or the ad side for a lefty)? Or would you make it a bit less extreme?

[@axelb.8685]

I'm interested in the answer, too. @jeff are you doing on the deuce and ad side different serves or adjust the stance to have the same serve?

[@mickhooker9]

I was thinking the same thing. I’m right handed . My serve definitely increased with pace when serving to the Advantage side. But when I serve to the deuce I can’t seem to get my feet in the right position and get the same effect. .. it would be really handy if Jeff showed the serve on both sides

[@davidjimenezortega7643]

mickhooker9 45º with the line in the other side and it will work perfect.

[@jisink]

The stances here apply to a lefty in deuce court or righty in ad court. In the other court, rotate the whole stance a few degrees towards the service box you’re aiming for. Federer does exactly this. Awesome video by the way.

Amazing as usual!

[@andrewbrewer198]

[@JiraiyaSama86]

Definitely a simple hack that allows for more easy power. And it's definitely something I noticed a lot with players who have excellent kick serves. But more importantly, it's a very common theme I see with servers like Sampras, McEnroe, and Federer - having their backs turned to disguise the serve.

[@TennisEvolution]

Spot on! Thank you for watching.

[@williamsannuto8239]

Hi Jeff I love the stance. I am a lefty also. Went out last nite hit about 300 serves and with this stance it was alot easier for me to serve to the deuce court I felt free er but when serving to ad court it was more difficult with the stance to serve generally - going accross my body to hit the serve presented issues with toss, misfits and getting more pace and spin. Could u identify what I doing wrong ? Serving to deuce court I was bombing the serve, very consistent , a heavier ball more action on the ball via spin.

[@TennisEvolution]

Hi William. That's amazing to hear. I would need to see a video of your serve on the ad court to provide more accurate feedback. Please record one and send it to [e-mail]

Hi Jeff. Great lesson. How to find positon on the legs on the both sides (Deuce and Ad) and the toss on both sides. I feel it fine on the Ad side (I am righty and copy ur stance on the video) and I feel weird on the deuce side.

Good morning Jeff, I would like you to clarify the following doubts. How is the position of the feet when you change the quadrant to which you are going to perform the service, (right, left), especially e seems to vary the rotation of the body, since the relative position is not the same.

[@thetruth65756]

Hi Jeff! I had a question about the elbow the enemy tip. Is it ok if your elbow is correctly high during trophy position, but then dips down as you snap your arm and make contact? Or does it have to be high and never go down? Thanks!

[@thetruth65756]

One more question- in elbow the enemy, does the elbow at trophy position have to be completely parallel to the ground?

[@jazzmaster349]

From the ad side if my front foot is at an angle pointed to the far net post, then I turn my body so that my toss arm is parallel to the base line. My chess does turn towards the back fence at 45 degree angle. I then bring up my back foot and Arch my body upward. In the platform stance, my body cannot lean/arch back as much as when I bring my foot up, consequently I lose power when I don't lean back.

[@TennisEvolution]

Thanks for your comment Gregory. I recommend you to stick with what works best for you.

[@AirGuitar]

You have to loosen up! I have had the same problem with my serve, but I am starting to figure it out. You have to barely hold onto the racquet and let it do the work. If you have a continental grip and you’re loose and fluid with the swing and rhythm, then it should work. I am now serving with my pinky off of the grip to make sure I don’t end up tightening up too much.

Thanks for your comment Denio. I am 6'1" tall. Yes, you can definitley serve 120 mph serve. It all comes down to your serve technique, that's the secret.

[@AcidexMax]

Hey Jeff, cool video...but I just wanted to comment that I tried it and it it does give you better rotation and even helps to keep the toss in check but I think that maybe I would need to go progressively. I found making the front foot parallel to the line and the back foot more open to the back did put quite a bit of strain on my front knee, specially coming up for the shoulder turn to make contact. I'm 5.0 player and (50 y.o) with decent technique but I don't think I have the level of flexibility on the knees required to turn that much.

[@TennisEvolution]

Thank you for watching. I appreciate your feedback. Let me know if you need any help with strength and mobility exercises, will be happy to help.

[@Aaswing]

Hi Jeff, very interesting idea. What do you think about this? In addition to your exercise, what if you bring the back foot forward rather than backward? This may give better separation between your hip and shoulder (ie, more coiling of the body) when you go through a trophy position. The two exercises could be complementary.

[@TennisEvolution]

Thank you for watching! Great idea.

[@stephenmallaband3289]

I am 41, a former national junior and have tried many times to switch to a platform stance, but it just seems to mess with shoulder, and I have to switch back.

[@Better_Call_Raul]

Yes, front foot *parallel* to baseline and back foot externally rotated. It is critical. This will facilitate a natural shoulder/hip coil. I was forgetting to do this today with the front foot. Had my front foot pointing to the net post (common instruction) and couldn't figure out why my coiling was blocked out. Then I simply positioned my front foot parallel and it allowed me to coil freely... I also like to complete my coil before releasing the toss. Do not feel comfortable releasing the toss and then coiling away. Hope this is okay Jeff.

Jeff you have an amazing platform serve, but advising everyone switch to it is a little much. I find that the platform stance is harder on the knees, thus pinpoint is often prefered at the amateur level.

[@jonayosores9944]

Ah, the tennis serve. The hardest stroke in sports, especially if you learn late. Nothing intuitive about it. They say it's like throwing a ball. So why can't I serve a tennis ball harder than I can throw it?

[@TennisEvolution]

Hey Jona. The analogy of throwing a ball for the serve relates to the similarity in the mechanics for executing both actions. However, hitting your serve hard is the result of many other components. For instance, you need to have the right grip and its tension and proper stance as a basic foundation. Likewise, you need to have great mobility and strength on your body to get into the right positions consistently and hit a solid serve. We've got a comprehensive course to help any type of player despite his or her level and age to build a world class tennis serve.

Well, I'm surprised (pleasantly) as you are almost there so to speak with this video. Only one step is missing; a revolutionary step to tennis instructors like yourself, but sometimes a revolution in evolution can win you a Noble Prize as it did for chemist in 2018. However, it is just one-step, so you might consider trying it out this one-step and the hip rotation you seek for serve power will be available to you.

[@TennisEvolution]

Interesting Don! I'm excited to learn about it, feel free to share with us ;)

@@TennisEvolution I'm not sure you want to learn the physics. Talk to Ken DeHart (says he knows you) as he is aware of my work (via our phone conversations) and agrees with me (in part) that stepping off the back foot is the so-called revolutionary step (I speak of) to your evolutionary theory. Of course, there is more to the story. In fact, I have 3 ways in which you can improve the power of your serve stance, but all utilize stepping off the back foot. Newton's 3rd Law is largely wasted by most tennis servers. Once they leave the ground the opportunity is gone (like a fart in the wind as one of my tennis converts says). I'm not saying that you are wrong, just missing out on some physics know-how.

[@TennisEvolution]

Don R. Mueller, Ph.D. After all Your comments, I still am unclear what you are saying or trying to explain. Are you saying that Sampras was not efficient with his serve in a platform Stance where he leaves the ground

[@drbonesshow1]

@@TennisEvolution Efficiency in physics is mathematically expressed as e = (0 - 100%). However, rather than get caught up in energy efficiencies (input versus output) it would clarify this discussion to examine the deficiencies of the platform stance (and the pin-point or step-up stance) whether it's you or your hero Sampras performing it. BTW: I had a hero of sorts; Nolan Ryan. When I played pro baseball I got a chance to meet him (I'm taller). He threw 100 mph and I threw 95, but we both had a gift. Now I'm using my other gift in the Physics of Sports.

Even pros can have inefficient or flawed technique. Wawrinka could probably serve better and harder more efficiently by following the tip. Not to mention - he's an athlete. Some of the best athletes discover ways to hack in a way that's not practical for many others.

[@errorcode1133]

@@JiraiyaSama86 Not really. There are two different biomechanical ways to generate power and spin. One is rotation and other is "shoulder over shoulder" (what Wawrinka does). Some players are better combining both but some are better with one predominantly. It is just that some coaches are only seeing in their own tunnel vision. Btw, Wawrinka is serving faster than Federer. Difference is that pro athletes do what is most efficient for them, amateurs do whatever their coach imagine as efficient.

[@JiraiyaSama86]

@@errorcode1133 I know that he serves faster than Federer. But it's also important to note that Federer doesn't place as much emphasis on speed. Federer discovered early on 120 to 125 was generally enough, that there's no need to really crack it even higher. That on top of his excellent placement. The tunnel vision doesn't have to be a bad thing. Especially when it comes to marketing for a more general audience. When it's one on one, that's when allowances can be made. I wouldn't blanket that statement that pro athletes do what is most efficient, especially when it comes to biomechanics. More like what is more habitual. They do generally have a level of efficiency but that comes from practice. Point is that there's always room for improvement, and tweaks like this can be taken into consideration. That's why we see pros continue to make small tweaks not only in their games but also their strokes. Rafa being the most apparent example.
