Jiri Prochazka tested a submission defense technique he saw online by attempting it on grappling coach Nina Drama during training. In the video, Drama told Prochazka he nearly broke her arm and confirmed the technique works. However, Prochazka dismissed its effectiveness, stating it would not work against an MMA fighter and noting he had seen it on YouTube. The exchange was captured on video and shared by Nina Drama. The post provides a lighthearted look at Prochazka experimenting with techniques discovered online.
