Hello, Ive been wondering on how to give crazy strong topspin (forehand of course) do you guys have any tips?
It is a combined effect from all the different sources of power all working together in a well coordinated and tightly timed sequence.
Imo from my journey:
1. I had to figure out how to generate heavy topspin just with the forearm and fingers. Penhold is different to shakehand but for me I use the index finger and thumb lever arm combine with forearm pronation + forearm snap to really spin the ball. You have to experiment a lot with it.
2. Then you have to add in the upper body and the lower body to really amplifies the effect from the forearm and fingers. You have to find the Goldilocks timing that works to maximise the topspin generated.
3. Add in footwork to deal with balls to your left (pivot step), right (crossover footwork), front (bring left foot forward), and back (bring right foot backwards).
Some ppl go from step 2 to 1 which works also. I also see a lot of ppl who only did step 1 which they always try to spin the ball with arm only which is highly limited in power, spin and consistency. There are a lot of ppl who only did step 2, and they have great power and structure but miss a lot due to the lack of spin amplification in the forearm and fingers.
