Instead of hollowing you should be bracing. Abdominal bracing is simply contracting all the muscles in the core without drawing in our pushing out. Bracing makes the muscles contract, which gives a stiffness and forms a girdle around the torso. When we brace the entire abdominal wall is activated binding all three of its layers together and giving us a highly efficient form of stability making the abdominals and spine work together and in a strong and safe manner.
For superior core strength and spine stability abdominal bracing is the best way to go. The other great thing about bracing is it is a lot easier (and more effective) to do than hollowing. To brace simply activiate all the abdominal muscles to make them stiff. SOunds fimilar? If you come to Hybrid you would be sick of hearing "make your core tight" which is our cue for abdominsl bracing. Brace for the core to be Ace!!!!!
