thats not just 20kg plates. they have color. And we cannot see the color So its impossible to tell.

I would guess Its two yellow closest in = 15kg x 2 and then two reds 25kg x 2 that makes 80 kg on each side = 160kg + 20kg bar = 180kg and then it looks like one more tiny plate on each side. lets makes that a small 5kg on each side. which would bring it to 190kg
190kg = 418pound
so Around there at least lol.
kinda looks like a read one and then a steel 20kg to the left. dunno.
