Jiří Procházka tried out a choke defense technique he saw on YouTube by testing it on Nina Drama during training. Nina remarked that Procházka nearly broke her arm and confirmed the technique worked. However, Procházka dismissed its effectiveness, saying it wouldn't work against an MMA fighter and that he only saw it online. The lighthearted training exchange was captured on video. No further context about the specific technique or training session was provided.
