Jiří Procházka tested a submission defense method he found on YouTube using his training partner Nina Drama. In video footage, Drama commented that Procházka nearly broke her arm and confirmed the technique works. However, Procházka dismissed its effectiveness, stating it wouldn't work against an MMA fighter. The lighthearted training session demonstrates the fighter's willingness to experiment with techniques found online, though he remains skeptical of their practical application against professional competition.
