Here are my suggestions:Snatch: It looks to me like the bar is too far in front of you and you are using your arms to get the bar overhead. Instead, bring the bar in close to you, and push down hard with the legs as you extend through the legs and back. As you fully extend, aggressively shrug the shoulders. Then, pull yourself under the bar to catch the bar in the overhead position.Jerk behind the neck. You have good vertical alignment. As the weight gets heavier, you are not going to be able to pop the bar all the way up to a fully locked out position. You can see on your 235 jerks that you are using your arm strength to straighten your arms. If you did something like that in competition, that is called a press out and would be ruled a no good lift. What you need to do instead is to lower your body so that you catch the bar with extended arms. Front Squat: Looks good. The important technical parts of the front squat are a good solid lower back lock, upright chest and elbows up. You've got that pretty good.Keep up the good work.
mate, welcome to the sport. It's quite hard to be...well...quite good...but it's worth it.Further to what others have said, you really need to get your shoulders further over the bar. Try doing a drill my coach has gotten me to do when i lose my place. Start of doing a snatch (For example) deadlift, then high pull, then full snatch. So you start in the snatch position, then as fast as you can take the bar to your hips like a normal deadlift (with plenty of speed), lower the bar, then start again, this time, instead of stopping at your hips, shrug (not pull...shrug the bar as high as you can. Then, do the entire lift. When in the starting position, i've found it useful to keep mindful of a tight feeling in my hamstrings, that tells me that i'm ready to go.
