"I prayed all this time, hoping that Illia would recover," his wife, Anna, told Belarusian media, according to The Daily Mail. "I spent every day by his side, hoping, and his heart started beating again for two days, but the doctor gave me the terrible news that his brain had died.

"I thank everyone for their condolences. It's very heartwarming to realize that I am not left alone in this world, and so many people have offered me help and support."

Yefimchyk told Muscular Development in 2020 he tried to emulate Arnold Schwarzenegger with his bodybuilding journey.

He earned the title of "world’s most monstrous bodybuilder" given the work he put in to develop his size and strength. He was 6 feet tall and 340 pounds and was able to bench press 600 pounds, do 700-pound deadlifts and perform 700-pound squats, according to Muscle & Fitness.
