Shoulder - Transverse Adduction
- Intermediate
- Compound
- Timed hold
- Shoulders
This isolation movement targets the pectorals and anterior deltoids by drawing the arm across the body's midline, enhancing horizontal shoulder stability and muscle control. It is an effective way to build mind-muscle connection in the chest and shoulders without external weights.

Muscles worked
Setup
- Stand with feet shoulder-width apart and core engaged for stability.
- Extend your target arm out to the side at shoulder height, palm facing forward and elbow slightly bent.
- Place your opposite hand on the inside of the extended arm's wrist to provide manual resistance.
How to do it
- Exhale and pull your extended arm across your chest toward the midline while using the opposite hand to provide constant, steady resistance.
- Maintain a controlled 2-second tempo as you move the arm through its full horizontal range of motion.
- Inhale and slowly return the arm to the starting position, maintaining light resistance with the opposing hand to keep the muscle under tension.
Form checklist
- Keep your shoulders pinned down and back to avoid shrugging.
- Ensure the moving arm stays parallel to the floor throughout the entire arc.
- Keep your torso and hips facing forward; do not rotate your body to help the arm move.
- Maintain a soft bend in the elbow to protect the joint.
Pro tips
- Focus on squeezing the chest muscle as the arm reaches the center of your body to maximize peak contraction.
- Use the resisting hand to create 'smooth' tension, mimicking the feel of a cable machine.
Make it harder
- Increase the manual pressure from the resisting hand throughout the entire range of motion.
- Add a 3-second isometric hold at the point of maximum contraction (when the arm is fully across the chest).

- The shoulder - transverse adduction requires no equipment — just your body weight.
- Is the shoulder - transverse adduction good for beginners?
- The shoulder - transverse adduction is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
