What is bracing technique?

The bracing technique, in the context of weightlifting and exercise, is described by Andrew Huberman and guest Andy Galpin as a method to stabilize the torso, likened to a cylinder, by filling it with air. You're encouraged to visualize your torso as a can of soda water—if the can is full and unopened, it's much harder to crush than if it were empty or indented. To create the brace, you essentially use air to push from the inside out and muscles to push from the outside in. This method avoids over-compression, such as relying too much on spinal erectors, which is not ideal. The bracing technique should allow for some natural movement, and you should be able to speak and breathe normally while maintaining the brace, even during a maximum effort lift like an overhead press or row 1.
