Hi zeio,

Thank you for the subtitles in the videos! This is very interesting since lots of people, on a lower level, have difficulties with the concept of rotating the waist.

The way I understand the concept of flexion in the hip, this results more in an upwards movement while playing VH Topspin while the concept of rotating the waist gives a forward movement.

Could you explain how to generate a forward movement when using flexion of the hip?

Thank you!
Best regards

Glad to be of help.

That's right. To do what Li Sun does below, you need a combination of hip flexion/extension, internal/external rotation and abbduction/adduction of the hip, in order to produce both forward and upward movement. To keep yourself upright, your knees and ankles move accordingly as well. Li Sun refers to the entire motion as hip flexion probably because it contributes the most due to its range of motion, as can be seen in the super slomo of ML's forehand loop.

In tennis forums the expression « kinetic chain » is often mentioned to underline how to avoid loss of power during the stroke and maximize the energy input that translate into paddle speed. I like to see coaching as continuous support of that kinetic chain. It helps having fewer words to express a goal before developing the related chapters and moving parts that kick in.

Hi Zeio, do you feel that the above video deserve a new thread of its own?  I personally have no idea on how to hit first then spin and I suspect nor does many others.

I thought about that, but I feel the concepts presented are all interconnected. By keeping them together I hope to make it easier for people to get a better grasp of the whole picture.

As for hit-brush, focus on getting the ball across the table(hit) first and work on keeping it on the table(brush), as demonstrated by Li Sun in the another video. I will get that one translated some time later as it's long.
