Sinistra was nicknamed "the Undertaker", and at one time was called "Belgium's strongest man".[3] Opponents that Sinistra defeated included Stefan Leko and Dževad Poturak, while he was defeated by Badr Hari[4] and Grégory Tony.

Sinistra, an anti-vaccinationist, was unvaccinated and a denier of COVID-19. When he became infected with COVID-19 in late November 2021, he would not acknowledge he had it. He was admitted to hospital but voluntarily discharged himself soon after. He died of COVID-19 complications in Havelange a few weeks later.[1][2][5]
