I read a Frederic Delavier’s book « Strength Training Anatomy » and there is good stuff.
Standing with your legs slightly apart. Take a dumbbell in each hand in pronation. You can keep dumbbells on your thighs or on the side :
Inhale and make an alternate raise of your arms forward (or antepulsion) until your eyes level.
Exhale at the end of movement
This exercise work mainly deltoid’s anterior beams, clavicular beam of the pectoralis major and a little less the rest of deltoid. In all arm raise movements, scapula fixators (shoulder blades) on rib cage such as anterior serratus and rhomboids, are also used allowing humerus to tilt on a stable support.
