Performing the: A Step-by-Step Tutorial Diagonal Flexion Neck Stretch
Slowly tilt your head to the right, bringing your ear towards your shoulder until you feel a gentle stretch on the left side of your neck.
Now, gently turn and lower your head diagonally as if you're trying to look into your right pocket, which will increase the stretch to the back left side of your neck.
Hold this position for about 20-30 seconds, breathing deeply and relaxing into the stretch.
Slowly lift your head back to the center and repeat the process on the other side.
