What this muscle is
From the top of the shoulder socket, through the shoulder joint, to the radius. It bends the elbow, turns the forearm palm-up, and also steadies the front of the shoulder.
Why it gets uncomfortable
Curls plus overhead pressing; still lifting when the front of the shoulder is unsteady; a sudden heavy lift.
How it usually feels
A deep ache at the front of the shoulder together with the front of the upper arm; a pulling pain when the arm reaches back; sometimes a stab at the front of the shoulder.
What helps
Hand on a wall, arm straight back, thumb down, body tipped slightly forward. Hold 20 seconds. If the front of the shoulder keeps stabbing, see a doctor.
