Sometimes the most useful training ideas are the simplest. A recent video shared on Instagram by Bujinkan New York Dojo offers Bujinkan practitioners an engaging exercise combining an arm lock, rolling and a last-second counter.

The drill begins with one practitioner applying an arm lock while their partner accepts the technique rather than attempting to fight against it. As the pressure is applied, the defender learns to relax and allow the body to move with the technique. Rather than meeting the lock with strength and tension, they swiftly roll away, using the movement to escape.

The exercise doesn't end there. As the defender completes the roll, they seize the opponent's wrist at the last moment and apply their own wrist lock, turning the escape into a counter.

Roll, Escape, Counter

The sequence creates several training opportunities in one movement. The initial lock encourages flexibility and relaxation, while the roll develops body movement and escape skills. The final wrist grab adds an element of timing and awareness, requiring the defender to recognise the opportunity to counter while moving.

An important part of the exercise is learning not to resist unnecessarily. Attempting to overpower a joint lock through strength and tension can increase the risk of injury. Instead, the drill encourages the student to accept the attack, stay relaxed and use movement to create an escape.

It is also a good example of how partner exercises can keep regular Bujinkan training fresh. By turning fundamental skills such as rolling, evasion and joint locks into a flowing challenge, practitioners can work on familiar principles while introducing an element of unpredictability and fun.
