Here are a few slices from my last session - I think my slice backhand is decent, but I can’t help but feel that something is still a bit off… I’ve noticed when reviewing footage back that my wrist tends to move at the last second (totally subconsciously, I didn’t realize this until seeing it on video), and my racket face turns to face the left side fence. I’ve fixed this to some degree but the issue still does show up. I think I might be too close to the ball and my brain is moving my wrist to adjust for my bad positioning? Anyways, any pointers or advice for improving my slice would be appreciated!

Two decent (for me) flat serves here, though I think there’s pretty big room for improvement. I believe my take-back and trophy position are solid, but I feel looking at the footage I’m not getting a full racquet drop. I find my arm also gets really sore after hitting flat serves for a while. Any advice? If my diagnosis on the racquet drop is right, what are some good pointers or mental cues for correcting it?
