To execute a side arm pose (specifically in the context of physique posing, like a side triceps pose), twist your upper body without twisting your lower body. This reveals more of your v-taper and creates a nicer taper, giving the illusion of broader shoulders.
In more detail:
- Keep your lower body facing forward: The primary action is in your upper torso.
- Twist your upper body to the side: Rotate from your waist upwards. The degree of rotation will depend on the specific pose and your physique.
- Focus on revealing your V-taper: Adjust the twist to emphasize the lines of your back and the width of your shoulders.
- Maintain good posture: Avoid slouching. Keep your chest up and your shoulders back (before twisting).
- Flex the muscles: Flex your triceps and other relevant muscles to accentuate your physique.
