Limbs are stronger when connected together.
You can create stronger frames and generate more force by connecting your limbs together. This is especially useful when defending and making space by creating frames.
Note that you can also create kinetic chains by connecting your limbs to your core.
Examples of kinetic chains include:
- Connecting your arms when framing from bottom side control
- Pulling your opponent’s arm tight to your torso when attacking a Kimura (as opposed to pulling with just your arms)
- Curling your core into your opponent when attacking a guillotine (as opposed to yanking on your opponent’s neck).
