Your grip is wrong (it needs to be at least continental, but probably eastern backhand. Grip changes are vital in racket sports), your contact point is wrong (its 1 o’clock, it needs to be 11 o’clock, so over your left shoulder), and your body shape is wrong (your left arm should be be up and your shoulders need to be turned - your knees need to bend to ‘fetch’ the ball from behind you).
I’m not going to get into pronation and supination because it’s complicated/difficult to explain in words, but you’re creating no internal shoulder rotation and no spin at all. It’s a flat smack, rather than a brush up the ball.
YouTube has loads of videos on how to do a kick serve in tennis. It’s the same technique - basically, except a few things in padel are exaggerated to get even more kick/spin, especially the back bend that a lot of the pros do. There’s a risk of injury in that if you’re not fit and flexible.
However, if you’re a beginner, all of this is a bit irrelevant: you’d be much better off focussing on a vibora tbh. That’s the percentage shot. I have a good kick smash because I had a big top spin second serve in tennis, but I probably get to hit one or two a game. On the other hand, I’m constantly hitting viboras, ganchos and, when I get the chance, tap-outs. Hit a mint smash that comes back over the net or kicks out x3 always get a “nice shot”, but it rarely wins a match. Solid volleys, lobs and defence win padel games.
Hope that helps. Good luck 👍🏻
Thanks for the tips!! The grip should probably no.1 on the list. I start in continental but for some slip out of it.
I definitely agree on the points re winners in games. All my winners in games are vibora, ganchos and chancletazos / backhand volleys. Occasionally a nice drop shot and tap outs.
Learning to hit a kicksmash is primarily because it looks cool honestly and good for content. Second reason is as a shorter guy I get lobbed a lot, so I focused on bajadas for the deep lobs and viboras for the shorter ones. It would be great to eventually add a kicksmash to the arsenal for bad lobs.
"Looks good for content" 🤡
Learn to fundamentally play the game, that will be good for content. If you want to really learn it, take 2 lessons from a pro. You are pretty far away from the correct form here.
