It is Jiu-Jitsu time. You are rolling, and your training partner secures your wrist from the top side control or the mount.
The keylock is a popular submission that may hurt your shoulder if you don't tap or escape.
In this class, master Rickson Gracie explores the angles you may use to survive and escape:
- Angle your elbow properly
- Comb your hair
- Flip your hips and land on top
Even if you grasp the concept, you must carefully practice the move repeatedly before trying for real.
