Unlocking mobility with PNF stretching 🙌 First, we activate the posterior neck muscles isometrically → they contract fatigue. Next, the body relaxes, allowing us to safely move beyond the barrier for a deeper stretch. PNF = proprioceptive neuromuscular facilitation Here’s why it works (simple): after the muscle works hard, it naturally ‘lets go,’ making it easier to stretch further without forcing it. Here’s why it works (technical): the isometric contraction triggers autogenic inhibition, lowe
