Undefeated Dutch two-division world champion Reinier de Ridder had the opportunity to train with heavyweight grappling legend 'Buchecha' Marcus Almeida at American Top Team gym. The two ONE Championship fighters were able to spend some time rolling together and sharpening their skills.De Ridder, who has an upcoming world title defense at ONE 159 on July 22, described the experience in an interview with ONE:“It was a big honor. I came there, I arrived a little late, but they finally let me in. I stepped on the mat, and ‘Buchecha’ was training with someone else. But he said, ‘Let’s train together.’ So we got in like an hour, an hour and a half of straight training."ONE Championship@ONEChampionshipReinier de Ridder bulldozes through!
