I read a Frederic Delavier’s book « Strength Training Anatomy » and there is good stuff.
Sitting with your back straight. Take the barbell with your hands in pronation resting on the top of your chest :
Inhale and press the barbell over your head
Exhale at the end of the movement
This exercice works anterior and medial deltoids, upper pectorals, upper trapezius, triceps and serratus anterior.
You can do this exercice standing but be careful, don’t arch too much your back.
When you press the barbell with your elbows forward, you work more your anterior deltoids.
When you spread your elbows when you press the barbell, you work more your medial deltoids.
There is several machines to do this exercice more safety.
