1 - crossfit games organizer deadlifting (very poorly)
2 - guy setting up for a deadlift, or maybe he's going to try and clean it, but yes it does look like it's in a crossfit gym 3 - looks more like a HIIT class offered through a regular gym, but I could be wrong
4 - just a dude attempting a zercher squat, but yes in a crossfit gym
5 - oh look castros still going for a deadlift, funny
6 - oh look that guys still setting up for oh yes mixed grip, it is indeed a deadlift 7 - this looks like a demonstration/advertising for crossfit but taking place on a catwalk? I am legitimately confused by this.
8 - ┌༼◉ل͟◉༽┐
9 - hey look it's the sledgehammers again 10 - and castro again
11 - dude still setting for for DL
12 - dude doing kipping (actually butterfly) pullups and attempting to take flight.
13 - sledgehammers....
14 - castro
15 - deadlift guy (not convinced that the last two time he was up were not the exact same clips, but whatever) 16 - dude "punching" a girl in the stomach with the business end of a sledgehammer. Maybe trying to induce a miscarriage? Either way, clearly not a part of any crossfit sanctioned activity.

35 - castro finally gave up 36 - (nothing) what the hell I wanted to see the other guy deadlift

Other than the guy doing zerchers that were clearly way too heavy, and the dude flying off the pull up bar due to slippery hands, there was nothing inherently dangerous about any of that. Tell me again how they were permanently fucking up their body.
