Why don’t you bring down the weight to a comfortable number that you can do. Such as 135 or 225. And focus on your form.
Clearly 355 is way too much for you.
Your wearing knee sleeves you have the pussy pad on.
How much more assistance do you need? Why not just drop the weight?
I will say this and I rest my case 405 will completely obliterate you.
He's literally destroying himself to show off to a bunch of guys who think he's a retard.
That was hard to watch. Like watching someone do squats for the first time. Reminds me of all the first-time power lifters going for a max attempt.
Terrible form, too much weight, bad walk out, crooked depth, uneven lift, almost fell over and hurt himself.
This is too much!

Back off the weight, ditch the tampon and belt. Do BB front squats to full depth with 225 until you figure out how to squat.
What a disaster.
405 my ass.
