Short warm-up for shoulder mobility - just a few minutes to relieve tension after working at the computer and "unpack" the upper back.

Gentle movements without jerking:
✔ improve shoulder joint mobility
✔ reduce tightness in the neck and trapezius
✔ help align posture

Can be done as a standalone mini-practice or as a warm-up before a workout.
With care for your shoulders - they carry a lot 😉
