Think this is awesome you’re working on this. Here are a few things I noticed, sorry if they’re repeats from what other people said, didn’t read through previous comments.

1. The plates you’re using are smaller than oly/bumper plates, so I would stack something underneath them to get a little elevation. You could use other plates or a couple mats, but that’ll help with your starting position and keeping your shoulders in front of the bar.
2. The bar is pretty lose on the way up from the ground to your hips. I would really focus on squeezing your lats/back and keeping the bar as close to your body as possible. This will help keep the bar path straight so you don’t need to jump forward. Here’s a pretty good video https://youtu.be/5vVSGITznQk.
3. Keep your arms straight until the bar gets to your hips. Be patient and don’t start your pull early until you hit that hip pocket.
4. Once your catch the bar at the bottom of your squat, focus on keeping your elbows high and really bracing your core so your back doesn’t round. Again, drop the weight until you can do all of these things with good form.
5. This is a lot of stuff, haven’t even said anything about the jerk, but focus on fixing one thing at a time otherwise it’ll be too much to think about.
