The Arm Sling

The Arm Sling is a powerful position that can be used for control or to set up attacks. It begins from the cross side position, where you would typically go for a Kimura. However, if the opponent is too strong or you're having difficulty breaking their grip, you can transition into the Arm Sling.

1. From the Kimura position, take the lapel that's closest to you, pull it out and turn your palm up to get a grip. Ensure that the lapel is anchored in the belt.
2. Once you have the grip, come off your opponent with your chest behind their shoulder and their back to secure the position. This prevents them from coming in towards you, which would make it more challenging to finish the technique.
3. If the opponent's belt is loose or their lapel falls out from underneath their belt, you can use an alternative grip. Open up their pants and insert four fingers. This provides a solid position even without the lapel in the belt.
4. However, this alternative grip can be uncomfortable for your hand when attacking certain positions. It works best for a few specific techniques.
5. One tip to remember which way to throw your arms and grab is to attack the Kimura first. This helps you remember which arm is already in. If you can't secure the Kimura, turn your palm up, open the lapel, grab it, and turn off.

This position is extremely strong and can be difficult for even experienced practitioners to escape from. It's a traditional grip from judo that has proven its effectiveness in Brazilian Jiu-Jitsu as well.
