7 KEYS TO SUCCESS
An effective compression lock hinges on your ability to execute seven points correctly. Seven of them are critical. They build on each other, so it’s best to learn them in order. 1) Opportunity Presents Itself: You must make the limb available to attack. In the case of the biceps slicer and leg slicer, that limb must first be bent. For the Achilles lock, you’ll need to have your opponent’s foot floating near your ribs to make securing the leg easier.
2) Thin Part Goes in First: When you’re inserting a limb for a biceps slicer or leg slicer, make sure you place the thinnest part of that limb near the flexed joint. That will enable you to easily tighten the lock by rotating and then pulling said limb. For the Achilles lock, position the bony part of your wrist on the Achilles tendon, not your meaty forearm. 3) Make the Attack Perpendicular: For maximum effectiveness in all these compression locks, ensure that your inserted limb is oriented at 90 degrees to the limb you’re attacking.
4) Control the Lock: Because your opponent will be resisting, you’ll need to maintain a solid grip on the flexed limb as you execute the biceps slicer and leg slicer. For the Achilles lock, concentrate on using your legs to control your opponent’s leg by pinching them together. That will minimize thrashing.
5) Work at the End: For the biceps slicer and leg slicer, compress the muscle at the end of the limb for maximum effectiveness. For the Achilles lock, position your forearm at the end of your opponent’s ankle (low on the leg). That will enable you to attack the Achilles tendon instead of the calf muscle.
6) Not Tight Is Not Right: For all three locks, try to eliminate gaps. Get your body in tight. There should be no empty spaces between your attacking limb and your opponent’s attacked limb. 7) Use Your Entire Body: Think “body unification” when applying any of these compression locks. For the biceps slicer and leg slicer, add a rotation and pull to achieve a superior lock. For the Achilles, rotate your wrist slightly to dig your radius bone into the tendon. If your right wrist is on the tendon, rotate your wrist slightly clockwise. For all the techniques, use your whole body, especially your bridging hips, for maximum power.

Next, the author locks his right leg over his left ankle, which lets the opponent think he’s no longer in danger because he’s out of the guard
