Hey guys! First time posting here.
I started playing 6 months ago and have been obsessed with tennis. I recently felt like I hit a wall consistency-wise and I felt like my timing was struggling. I also read here that recording yourself can help you see which areas you can improve and so decided to purchase SwingVision since it was on sale for Thanksgiving.

Here’s my problem: i don’t know how to explain it but I’ll try… 

I feel like I developed the wrong habit of hitting my forehands with a “fixed” wrist. I try to do the full motion of finishing with my elbow out but that doesn’t help my wrist. I have tried looking on YouTube for tutorials but everyone just says to keep your wrist loose and don’t force pronation. When I look at my own forehand I see a weird forehand shape in comparison to the videos and I feel that I go vertical with my arm and fixed wrist to create spin (if that makes any sense). 
I am losing my mind because I can’t really pinpoint what it is that I’m doing wrong. Should I force the wrist and forearm to pronate so that the head of the racket finishes first? 

Any tips would be appreciated. Sorry for the long post. 

I want to figure out what’s wrong with my forehand
