Hey Marios,
Yes I’ve seen some of Timo’s videos with tips and they are good ones for sure. All the ones you’ve listed above I think are good to focus on to help improve.
The abs tension is definitely something that most players actually don’t think about, or at least they forget about it often. I would say that myself and Dan do think about it but probably not in the same way Timo mentions. Usually I focus on tensing the abs as I play the shot and through the contact of each shot for extra strength and to keep balance and a good stable body position. This I do think is important so you don’t lose your centre of gravity and keep a good position at the table.
I don’t think many players actually tense their abs the whole time like Timo mentions but that clearly works well for him. I would definitely suggest trying to focus on abs tension throughout the contact, especially on shots like a powerful forehand topspin where you are looking to generate power but not lose balance etc. Also this will help a lot when lifting backspin to give you the strength from your body and not just the arm.
Cheers, Tom
