When trying to achieve full external rotation of the hips or hold external rotation of the hips it’s not a good idea to tighten the gluts.
WHEN YOU’RE TIGHTENING THE GLUTS YOUR ACTIVATING YOUR GLUT MAX MUSCLES WHICH MAIN JOB IS TO CREATE HIP EXTENSION WHICH YOU USE WHEN DOING AN ARABESQUE.
This in turn takes away from properly activating the hip external rotators and compensating a movement by using the wrong muscle group.
