The Training

Training sessions at Lion’s Den Leiden take place on Monday, Wednesday, and Saturday and are fully focused on No-Gi Jiu Jitsu and Submission Grappling.

Each session follows a clear structure. We begin with a focused warm-up, followed by technical training covering takedowns, positional control, pressure, and submissions. Emphasis is placed on efficient movement, decision-making, and applying technique under realistic conditions.

Training is organized in blocks around key grappling positions such as guard, mount, side control, back control, and half guard. From these positions, we practice attacking, defending, and escaping, ensuring techniques are immediately applicable.

Sessions conclude with sparring, including both free sparring and situational rounds, allowing athletes to apply techniques under resistance and further develop their personal grappling style.

Training is suitable for both beginners and advanced practitioners, with room for individual growth within a strong, respectful, and supportive team environment.
