Description

Stand with your feet hip-width apart. Extend your arms out to your sides at shoulder height. Cross your arms in front of your chest and then open them back up to the sides. Repeat this motion.

How to Do Arm Crossover

  1. 1
    Setup

    Stand tall with your feet hip-width apart and a slight bend in your knees, maintaining a neutral spine.

  2. 2
    Setup

    Extend both arms straight out to your sides at shoulder height, palms facing forward, ensuring your shoulder blades are slightly retracted.

  3. 3

    Exhale as you quickly cross your arms in front of your chest, bringing one arm over the other, aiming to touch your forearms or elbows together.

  4. 4

    Inhale as you swiftly open your arms back to the starting position, extending them wide to the sides to feel a stretch across your chest.

  5. 5

    Alternate which arm crosses on top with each repetition to ensure balanced activation and mobility development.

Tips

  • Keep your core gently engaged throughout the movement to prevent your torso from twisting and maintain stability.
  • Focus on a controlled, rhythmic motion rather than just flailing your arms; this ensures proper muscle engagement and minimizes injury risk.
  • Increase the speed slightly as you warm up, but always maintain control to fully engage the chest and shoulder muscles through a wide range of motion.

Common Mistakes

  • ×Rounding the shoulders forward during the open phase reduces the stretch on the chest; instead, keep your shoulder blades slightly pulled back to maximize chest expansion.
  • ×Not fully extending the arms out to the sides limits the range of motion; ensure a wide opening to achieve a complete stretch across the pectorals.
  • ×Allowing the arms to drop below shoulder height diminishes the target muscle activation; maintain arms at shoulder level throughout the entire movement.
