One of the key elements of effortless tennis strokes is weight transfer.
But tennis players often misinterpret the idea of transferring their weight because they tend to lose their balance in their attempts to transfer weight into the ball.
Today we’ll take a look at a simple mental image that helps you transfer your weight correctly without losing your balance. In the process, we’ll also “upgrade” the usual instruction of “bend your knees”.
Not Using The Legs Properly When Hitting Groundstrokes
Let’s first take a look at the most common mistakes players make with their legs as they hit forehands and backhands:
- No Legs – the player hits a groundstroke while keeping their legs more or less extended/straight. There is an obvious disconnect between the lower and the upper body.
- Legs Extend Too Quickly – the player seems to use their legs, as they do bend their knees and extend, but they tend to extend the legs too quickly. This results in them hitting the ball again while having their legs completely extended, so there is no real energy transfer from the legs into the stroke.
- Legs Stay Bent – the player does bend their knees as they hit lower balls, but they stay down as they are hitting the ball and, in some cases, actually move downward while hitting.

Three common mistakes: no legs, legs too early and legs staying bent.
A Simple Mental Image For Synchronizing The Legs
When players are instructed to bend their knees as they execute their forehands or backhands, they tend to follow that instruction literally and just move up and down.
If they time that movement right, then that can help a bit and bring some power into the stroke, but they are still missing the actual weight transfer that makes hitting much more effortless.
Rather than visualizing bending your knees, it is much better to use the mental image of moving your pelvis through space in the same shape as your swing.

Move your pelvis in the shape of the swing and maintain good balance.
Of course the movement is not as big in space as is the swing, but it follows the same shape and moves in sync with the swing.
That’s what really helps transfer weight into a tennis groundstroke.
When we visualize and attempt to move the pelvis in space in the shape of the swing, then we will use the legs correctly without even thinking about them.
The legs will simply execute the movements necessary to move the pelvis in space like you imagine.
That frees your mind from thinking about your legs, resulting in smoother movements with a horizontal element, which is the weight transfer into the shot.
The downward and upward element (vector) of the legs and pelvis movement helps with adding lift and topspin to the ball.

My pelvis will follow the yellow line as I am executing the one-handed backhand stroke.
Note that this way of moving your legs and pelvis (in sync with the swing) only applies to flat and topspin strokes and not to slice strokes.
Also, all demonstrations above were done in a neutral stance where the weight transfer is more obvious and more important.
You might be wondering if you can use the same mental image of pelvis movement in space as you hit open stance forehands and backhands.
The answer is yes, but in a much smaller way.
If you try to transfer weight too much forward while you are in an open stance, you will lose your balance and fall forward.
Therefore you need to prioritize balance and stability while you try to move the pelvis in sync with the swing. The movement is still there, but it’s smaller than in the neutral stance.

Balance is priority here otherwise you will fall forward and likely miss the shot.
In conclusion, using weight transfer in tennis is one of the keys to hitting strokes effortlessly, but players tend to do it incorrectly.
They either fall over the front leg in neutral stances or just move up and down with their legs, following the ineffective instruction of “bend your knees,” which doesn’t add any forward force.
A simple mental image of moving your pelvis in space in the shape of the swing helps you engage your legs as well as transfer weight into the ball.
The more your lower body syncs with your upper body, the more effortlessly you’ll play.

As a coach myself, I would like to thank you so very much for the best technical and mental instructions that you so generously make them available to the tennis communities.
Thank you for the kind feedback, Golshani!
Will certainly try. Thanks for the tip
Hi Thomas:
Very good simple, concise explanation & demonstration of correct weight transfer in tennis.
Thanks lots,
Aine
Glad it helped, Anne!
Very creative way to transfer weight. As I am 66 years old, I have noticed the absence of rotation of body in older players. Older players use hand coordination to compensate for lack of movement, and stop using pelvis and body rotation even when there is sufficient time available for a proper stroke.
Yes, William, the “old school” of tennis teaching was all about the linear arm movement which one could do only without much body rotation.
It Look good and make sende- question: and what about the kennetic chain, that is Differential the move of the Body and the Strokes?
This trick activates the kinetic chain by connecting legs with the upper body, Werner.
It’s just a very good trick because you don’t have to think about legs but you visualize hips / pelvis movement in space and your legs will automatically work correctly by trying to move the pelvis this way therefore you will establish good kinetic chain.
Hi Tomaz,
this is wonderful! It’s also in line with what you mention in your tennis illusion posts, that the body movements are much smaller than the movement of the racket. It helps a lot to take the ‘thinking’ out of the body turn.
thanks a lot for your valuable advice!

Reinforces the kinetic chain; well done
Thanks Tomaz
I will give this a go. It seems movement to the ball is key here for efficient balance. As a recreational player we all have to deal with a variety of trajectories of the ball. Great video as usual.
