I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.
Lying on a horizonzal bench with your butt glued to the bench and your feet on the ground :
Inhale and press
Exhale at the end of the movement
This guided exercise works the pectoralis major, mainly the sternal parts at the end of the movement. This guided exercise also work a little bit the triceps and anterior deltoids.
Variant : By pulling out your chest and arching your back, you work more the lower part of your pectoralis major (chest). But beware, this technique is harmful for people with back problems.
