I am a high school sophomore and have been playing for about 5 years now. I used to take group classes, and even a few private lessons, but have played primarily for school or with other people for the past 2 years. I played a lot of USTA last year and won a lot (I play in the Chicago area, it's pretty competitive here), and even made the varsity team last year (but didn't get to play any matches because covid) and was playing really well. I was pretty consistent and my shots had a lot of pace and spin, and I was able to control the ball really well. Ever since then, I have been playing 3-4 times per week, and my performance has drastically dropped. My footwork is all over the place, My shots are weak and flat, and I can barely put the ball where I want it. I have tried watching this dude in order to improve, and it kind of helped, but I still am far below what I used to be. I tried taking a week off and just focusing on working out and improving my strength and flexibility, but to no avail. Here is a video of me playing that you guys can critique. I am the person closest to the camera. I guess my main issue is just consistency, and from there I can improve the other stuff.
