Yaroslav Radoshkevich, 20, was attempting a seriously heavy squat at the World Raw Powerlifting Eurasian Championship in Khabarovsk, Russia when the sickening incident unfolded.
After failing with his first two attempts at the weight, Radoshkevich was doing everything in his power to make lift number three successful.
In vision that his since gone viral, the young Russian can be seen straining as squats down low, before everything goes horribly wrong, his right leg snapping under the huge load.

Radoshkevich was diagnosed with a compound fracture on his right tibia at a nearby hospital, the injuries likely to end his young career.
“I can hardly return to this sport following such an injury," he told Russian news outlet Amur.Info.
"I had achieved a lot but I will have to quit my hopes and ambitions as rehabilitation will approximately take six months."
A likely contributing factor to the failed lift was an ankle injury Radoshkevich carried into the event,
"I thought that it (my ankle) was just pulled, so I did not pay attention," he said.
