On October 4th, 2025, RŌL Academy had the pleasure of hosting a powerful seminar led by Professor Jesse Walker. The session focused on advanced control concepts, diving deep into one of the most overlooked yet essential details in Jiu-Jitsu — the difference between traction and tension of the arm. Professor Walker broke down how these two forms of control create entirely different outcomes, influencing leverage, grip efficiency, and the ability to maintain dominance during transitions. His teaching style blended precision with practical application, giving students valuable tools to refine their understanding of positional control and submission setups. The energy on the mat was electric, and the insights shared left a lasting impact on everyone in attendance.
