Should i put my elbow a bit high to do this stroke? Also, i think i’m not waiting enough the ball, in what time i should hit it? Early descending? And where is the start positioning? Should i start with my racket closer to my body?
There’s some footage
I think the elbow position looks ok, and it's stable (i.e. not moving around everywhere), which is most important.
As for whether you're waiting enough or not, the answer is.... it depends. Your current contact is off the bounce (early ascending), which is good for warming up or redirecting your opponent's speed and spin. Playing early like this can be an offensive weapon by limiting the time your opponent has in setting up for their next shot.
When playing this close, you could probably make some slight adjustments in keeping the ball a bit lower and adding a bit of speed on the ball, as your follow through is quite loose, which can affect stability (i.e. the ball is more likely to overshoot the table). I normally do this by slightly pressing my thumb down on impact, which provides some stability and force on the ball. Timo covers it briefly here:
You can also try and practice the backhand topspin at different depths, e.g.:
- Close to the table, off the bounce
- One step back, on the top of the bounce
- Two steps back, as the ball is descending
The advantage of training at different depths is that it should help you to learn to make adjustments. Also, in match conditions, good attacking players will force you away from the table, so learning how to make those adjustments will be really important as you keep getting better.
