Crossbody Arm Swing
The crossbody arm swing is a dynamic bodyweight exercise targeting the deltoids and upper back. The rhythmic swinging motion improves shoulder mobility, increases blood flow to the shoulder joint, and serves as an effective warm-up or active recovery movement.
How to do it
- Stand with your feet shoulder-width apart and arms extended out to your sides at shoulder height.
- Swing both arms inward across your body simultaneously, crossing them in front of your chest.
- Return your arms back out to the starting position with control.
- Continue the swinging motion in a rhythmic pattern for the desired number of repetitions.
- Keep your core engaged and your torso stable throughout the movement.
Form cues
- Keep your arms at shoulder height throughout the movement.
- Engage your core to prevent your torso from twisting.
- Move in a smooth, rhythmic pattern without rushing.
- Breathe steadily as your arms cross in front of your chest.
Breathing: Inhale as you open your arms wide to the sides, and exhale gently as you cross them in front of your chest.
Common mistakes
- Swinging too fast or using momentum, which reduces control and joint engagement.
- Dropping the arms below shoulder height, which changes the angle and misses the target shoulder muscles.
- Twisting the torso back and forth, which shifts work away from the upper body and core.
Muscles worked
Primary: delts. Secondary: traps, chest, upper back.
