Brazilian teen bodybuilder dies due to suspected heart attack

The body-building community is mourning the death of 19-year-old Matheus Pavlak.

Pavlak transformed himself into a bodybuilder in just five years since he took the sports seriously to combat obesity.

He regularly participated in bodybuilding competition in Santa Catarina state of Brazil.

According to media reports, he was named “Mr. Blumenau” after he won a U23 competition last year.

Ex-trainer Lucas Chegatti posted an emotional tribute where he wrote as quoted by Mirror: "He had a brilliant future ahead of him as a respected athlete. God has his plans but it's hard to understand, I don't have the words to explain the weight I feel in my heart."

“I was Matheus’ first coach and I'm very proud to have had the opportunity to have cared for him like a son. I promised him that one day he would beat me and said and done, the first time we competed together against each other, he ended up winning," he said.

“He was no longer a part of my team, but I know I managed to form a great athlete. May God comfort his family and take care of our boy," he wrote.

The bodybuilder shared several videos of his physical transformation on Instagram.
