Watch This Guy Try to Break the 30-Second Pullup World Record

"I tried to beat the record for the most pushups done in 30 seconds, or at least the most I could find online... I wanted to beat it. And I beat it," he says. "So now it's time for pull ups."

He starts by finding a baseline to see how many pullups he can do in the time framefrom the get go, and he knocks out 23.

But he has to figure out how many pull ups he'll have to do to break the record. But upon a quick Google search, he can't find an official world record anywhere.

"Pushups are a easier than pullups. I'd say pullups are twice as hard," Browney says. So he settles on trying to do 25 pull ups in 30 seconds, about half the number of pushups he did in his initial #30secondschallenge.

On his first attempt, he notes that he was "swinging too much", and needed to contract his abs more. So on his second attempt, he hits 24, one short of his goal.

"Gotta contract the abs more," he says after doing a bunch more attempts, and failing to hit 25.

He's not wrong. One of the keys to a strong strict pullup is constant tension, although that won't make the move easierinstead, it should get even more challenging.
