For some, doing a box jump is hard enough as it is.

Now imagine having no arms, and being asked to nail one on camera.

That’s exactly what 14-year-old Tim, of Chicago, managed to do recently after three failed attempts — and the world is loving him for it.

“This is amazing,” wrote one Twitter user after footage of Tim’s jump went viral Tuesday.

“Tim is a beast!!!” another said. “The kid has a huge heart and the will to succeed!!! Gotta love that.”

Tim was at NubAbility Camp on Saturday in Duquoine, Illinois, when he nailed the 20-inch box jump on camera, according to staff.

The footage, which has been picked up by media outlets as far as Japan, shows the teen making three failed attempts at the jump — and almost storming off at one point — before he finally succeeds.

“Jump up on that box!” a coach can be heard yelling in support of Tim. “All the people that told you you can’t — right here! Jump on them, now!”

After finally getting up on the box, the teen screams out in celebration — and immediately bursts into tears.

“People get wrecked up on box jumps all the time,” said Sam Kuhnert, founder of the NubAbility Camp, in an interview with KFSN. “You see [Tim] take one last deep breath, and he goes for it, and he doesn’t give up.”

The clip of Tim’s jump was tweeted out early Tuesday by a man who was at the camp over the weekend named Brad Vinyard.

“My favorite moment from Nubability Camp,” Vinyard said. “Tim overcoming his fears and self-doubt and landing a 20” box jump.”

Social media users have been praising the boy for his determination — with many pointing out how they can’t even do a box jump with two arms.

“Holy s–t…that dude can waaaaay out jump me,” tweeted one person.

“If i had a quarter of this kid’s willpower, i wouldn’t be the lazy ass i am now,” another said. “This kid is my workout inspiration.”
