What would it look like to just have the right amount of leg drive on your tennis serve? Well, in this article I’ll go over the leg drive, one of the serve areas where most tennis players struggle.  

There are many coaches who just tell their players to use the legs and bend the knees more. However, I consider that this can cause issues and distract tennis players from mastering the serve fundamentals. 

For instance, they may lack shoulder turn or get the elbow in the wrong place. Hence, you should focus on what your upper body is doing instead of being only concerned about the leg drive. Simply ensure to have great rhythm on your tennis serve and worry less about your lower body. 

When I’m warming up, I just focus on having a smooth swing and a slight leg drive. I want to point out some of the common serve mistakes that I see being made out there. Consequently, I can explain how to get proper leg drive on your tennis serve.

Platform Stance

I find that when players get into a pinpoint stance, they might only be able to really push off their front leg and have less weight on their back foot. Therefore, I suggest getting into a platform stance. It will enable you to have the weight a little more equally distributed between the front foot and the back foot. Then, you want to essentially get to your trophy position.

When it comes to the leg drive, you want to feel like you’re able to drive off of both legs. Now, there will be a little more weight on the front foot, when you go to push off. Nevertheless, I see many players who just shift their weight forward and lose all of the weight on their back leg. At the end of the day power comes from the ground; thus, you definity want to use it appropriately.

First Move

Next, I want you to properly turn your hips and shoulders during the first move. Consequently, you avoid getting into a squatting position and having a big curve in the low back. 

One way to do it is learning how to turn the hips and slightly push forward into the front hip. This is what I call “tucking the tail”. I feel it happens naturally, when you just get the right amount of weight on the front foot and ensure that your hips and shoulders turn correctly. In fact, that’s how Roger Federer turns his shoulders on the serve.

Leg Drive On The Serve

How to use the legs on your tennis serve

I’ve seen and coached many players who have an excessive amount of knee bent on their serve. Thus, they get into a squatting position and lose a lot of power on their tennis serve. If you think of a vertical jump, you’ll go down and up pretty quick. The problem that I see with many players is when their toss is really high, they stay down for too long.  

You should be able to generate great power without a lot of leg drive by having a loose hand and arm. To summarize, focus on getting your upper body to work correctly, getting the rhythm, the tempo, and the shoulder turn. Second, I advise that you get into a platform stance to push off both legs. Third, stop squatting on your tennis serve. Instead, get a nice hip turn, so that you can push your front hip out over the line. Finally, get the toss in the right place to fire up to the ball precisely and avoid bending your knees too much.

    From watching your video I now know that I have been teaching my students correctly. I personally mimic Roger Federers service motion and it has helped me considerably in speed and accuracy. I am now trying to teach exactly what you are talking about. Thanks for the video.

  2. Noushin

    Many thanks for sharing your experience.

    I realize that this vid was not meant to address the toss however, you did specifically mention it in the last minute or so. I’ve had a coach that preferred that my toss should be a little in front of me. When doing my own investigations there are many slow-mo vids that show the top players keeping their toss (initial arm swing) in line and over the baseline. Your thoughts?
    Thanks for all the great tips in your vids; some tips have instantly solved certain dilemmas in my play.

      Ben, you have to find what works for you with the toss.

    Very helpful. I have been trying to address the leg bend with my students and your video has solved my problem. The emphasis on the hip turn made all the difference. Thanks

      So happy to hear it, Sandra!

    Dear Jeff,

    Thank you so much for sharing. I have been following your videos on youtube for quite a while.
    In my practice recently, I have been notice a problem that most coaches either online or on court did not signify enough. That is the LEG DRIVE.
    I had been practice a lot about the toss, the stance, the shoulder rotation, the pronation and etc. They helps but all of those felt like scattered pieces until I found leg drive to connect them.
    The fact is, our brain reaction to visual is about 250millisecond(not include the body reaction time) and the strike window we have is way much shorter than that. If we put aside leg drive, that means we are using our racquet/hand/body to search and hit a ball in the air. And that’s not possible. It may works when serves slow. If we use this search mode to strike hard, we get hurt and inconsistancy.

    Here come my point!!!
    As a result, our brains actually does not allow us to do much in the strike. All we can do is get prepared. What I do is I pace myself into the trophy stance with relaxation and then align my leg in back with the ball in the air, that’s more like a mindset, and just launch it. By doing so, all my body parts and the racquet will automatically follow the proper track like a released spring. That feels wonderful, effertless and most importantly painless.
