The Tongue as a Tell for your Pelvis

The connection between your tongue — your mouth — and your pelvis is intense. The correlation between tongue tension and pelvic tension is well documented. If you engage in a sport that requires a supple, ready-but-relaxed pelvis — that is to say, almost any sport known to humans — or if you want to enhance your balance, then check in with your tongue. If your tongue is soft and ready, well and good. If it is tight, I bet you your hips are tight. And if your hips are tight, then you have already squandered some of your power and equilibrium. Soften both, and you have the potential for power moves or balance corrections, as you need them.
