Technical sheet on stretching the Petit pectoral:

You are standing next to a beam (half an arm of separation), a bar… Parallel feet, knees slightly bent. You perform a lateral elevation of one of your arms (your palm of the hand will be in front), up to shoulder height.

When you reach shoulder height, you will flex your elbow 90° to form a right angle. Place the forearm and elbow on the contact surface and at the same time take a slight step forward with the opposite leg.

In this configuration, you rotate the head opposite the arm. Feel the stretch, you can even accentuate it by leaning your chest very slightly forward.
