Petra Kvitova – Forehand improvement to a higher 3.0 standard

Then over the years, the forehand has brought Petra some winners, but often also rather a quite serious amount of errors as some of the Forehand 3.0 principles have been often missing in her game. It was the reason why I have repeatedly criticized her forehand, (also) here on this site, in the past and why I have mentioned some hints towards possible improvements, also to Petra's surrounding, mainly since the later part of the 2015 season. It might be just a pure coincidence, but especially after...

Sebastian Korda – Clean 1st Service 3.0

Below, I am focusing on his 1st service technique as I have analyzed it during the 2017 French Open Junior Championships. Sebastian's service is dominated on the backswing part by a calm body pretension buildup and an almost straight tossing motion, both free of any major idiosyncrasies. This is followed by a solid push-off leading to a good extension and then by a very.....

Denis Shapovalov – Powerful 1st service 3.0

From the strokes, the service belongs to one of Shapovalov's strengths, but small improvements (part of the Tennis 3.0 Code seem to be missing) could probably make this leftie service to an even more of a constant weapon. Below, I am showing some of Denis' services at both the 2017 French and the 2017 US.Open. The opening of the racket...

Reilly Opelka – Rather troubled forehand

Below, I am comparing Reilley's forehands at these two above mentioned events. I am surely aware that the coordination and an exact footwork are challenging at Reilly's size, but what I am focusing at is the way how he approaches the given strokes as this gives me certain information about the mental image of the stroke in his mind. In the case of an optimal "3 Step Tennis Stroke Regulation", the player puts the priority at the creation....

Jack Sock – Strong service and forehand combination

In general, Jack has mastered in both strokes the art of the close to optimal body energy unloading (=Tennis 3.0), which goes over the targeted pronation of the entire limb (long-axis pronation). This targeted pronation is possible when, among other conditions, a perfect eye control of the ball leading to optimal spacing is present. Some of the other conditions necessary...

Jack Sock – Service 3.0

....they also made some improvements on Jack's backhand and then some serious work has been done on Jack's service, which can be considered as quite a weapon now. In this article, I would like to focus on some qualities of this "new Sock service", as he showed them at the ATP 500 tournament in Basel (SUI) few weeks ago already, just before the above mentioned Paris event....

Bernard Tomic – Service 3.0 – look back

One of the biggest would be his service. At 196cm (6'5''), Bernard has quite excellent bodily parameters for a powerful service and also his service technique is, despite certain weakness in his legs and core, since years very solid. The below-presented photos are from the 2011 Masters Series tournament in..

Sloane Stephens – Service 3.0 over the time

It was my real pleasure to have had the chance to work with Sloane in 2010-11 and updating her service was maybe the most enjoyable instant success of my coaching career in tennis. During our first meeting on the court in Florida in 2010, Sloane, as this is quite usual with most of the young players until today, didn't have a clear understanding about the (targeted) pronation. Following short verbal, visual and proprioceptive explanation of this motion and its key elements (including the Service 3.0 Code) from my side, Sloane wanted

Petra Kvitova – Dominant leftie Service 3.0

Petra's favorite strokes are the service and the backhand, which is a great combination for her as a left-handed player. Her forehand is a bit mistake prone, as I did write about it in one of the previous articles here. Below, I am showing some important details from Petra's dominant service through the years, from her so far the most successful 2011 season and then some rather recent ones. And there are some developments to be spotted...

Martina Hingis – Service over the course of the time

For many years, the service could have been considered as Martina's biggest weakness, mainly due to a suboptimal form of the pronation with the elbow staying rather too low and the racket traveling rather too much on the horizontal plane after the impact. Over the course of the years, Martina was able to improve it a bit and her pronation did look much better later in her career. With the elbow.....
