What made the difference between these two squats that resulted in a good lift @ 230kg? 

Bro crushed his organs

I like how you always go full depth even for the max lifts 💪

You screamed the second time. Everyone knows screaming adds +2 to sendage. Except the management at my gym, apparently... 😅

The bar shifted forward on the failed attempt, and stayed back for the successful one?

Gotta tighten that belt a coopla more notches

The answer is that he shifted his head back once he hit the sticking point, preventing him from falling forward and allowing him to grind through it.

A lady was watching the second one

Rage against the machine for sure

Vertical drive on second

The music was better on the second attempt 👍

2nd attempt he kept his head up and drove to the ceiling.

Your knees are caving in alot

He’s knees cave in, I would work on that 💯

Bar path was the difference
