Main muscles working (thicker lines)
Lie back on an incline bench with a dumbbell in each hand hanging at your sides, palms facing forward and out.
Keep the upper arms still.
Curl the dumbbells out and up, keeping the forearms in line with the side delts.
Finish with the dumbbells beside your shoulders, like a double-biceps pose.
Squeeze, then lower along the same path.
Breathing: Exhale as you curl, inhale as you lower.
Curl out to the sides
Shoulders on the bench
Slow on the way down
Flaring the elbows up and out
Losing the stretch at the bottom
Going heavy enough to shorten the path
Keep the load light; the stretched, outward path stresses the front of the shoulder and the elbow.
