Arm Crossover
Arm Crossover Exercise Description
Arm Crossover (bodyweight) trains the chest by actively drawing the upper arms across the torso and creating inward pressure between the forearms. The primary mover is the pectoralis major; the anterior deltoids assist with horizontal adduction, while the serratus anterior and scapular stabilizers maintain shoulder position. Because resistance is self-generated by pressing the forearms or palms together, you can create meaningful tension without equipment and stay in a comfortable range of motion. The goal is smooth, controlled adduction with a neutral spine, ribs stacked over the pelvis, and shoulders depressed—avoiding shrugging or excessive rib flare. Executed well, it reinforces sound shoulder mechanics for pressing and fly patterns while providing a simple chest-focused option anywhere.

How To Do The Arm Crossover Exercise
‘- Stand tall, feet hip-width, knees soft; brace lightly with ribs stacked over pelvis and neck long.
– Set shoulders down and slightly back; maintain neutral spine.
– Raise arms to shoulder height with a gentle elbow bend, palms facing each other.
– Cross the forearms in front of mid-chest (one forearm atop the other), elbows level with shoulders.
– Press forearms/palms firmly into each other to create inward tension through the chest.
– Focus on drawing the upper arms across the torso (horizontal adduction) without shrugging.
– Keep wrists neutral, elbows slightly bent, and shoulder blades stable—no excessive protraction.
– Breathe continuously; avoid breath-holding or bracing the neck.
– Release tension with control, uncross slightly, then repeat with the opposite arm on top to stay symmetrical.
Arm Crossover Tips
‘- Stand tall with feet hip-width, knees soft, and neck long before you start.
– Lightly brace with ribs stacked over pelvis to maintain a neutral spine.
– Set shoulders down and slightly back and keep them from shrugging as you move.
– Raise arms to shoulder height with a gentle elbow bend and palms facing each other.
– Cross your forearms in front of mid-chest with elbows level with your shoulders.
– Press forearms or palms firmly into each other to create inward tension through the chest.
– Focus on drawing the upper arms smoothly across the torso to drive the movement.
– Keep wrists neutral, elbows slightly bent, and shoulder blades stable—avoid excessive protraction.
– Breathe continuously, avoiding breath-holding or bracing through the neck.
– Release tension with control, uncross slightly, then switch which arm is on top to stay symmetrical.
Arm Crossover Beginner Introduction
Arm Crossover (bodyweight) is a simple standing chest exercise that relies entirely on tension created between your own arms rather than external weights. The movement brings the arms up in front of the body, folds them across one another, and increases pressure between the forearms or hands. As the upper arms sweep inward across the chest, the front of the shoulders and chest take on most of the work, while muscles around the shoulder blades and along the rib cage help hold the shoulders in a steady, comfortable position.
Because the effort comes from how firmly the arms press into each other, the challenge can be adjusted without changing equipment or setup. A tall, balanced stance with a relaxed neck and steady breathing supports smooth, controlled motion instead of jerky or strained effort. Alternating which arm crosses on top promotes a more even feeling side to side. This pattern mirrors the way the chest and shoulders function in many pressing and fly-style moves, offering a low-tech way to rehearse good shoulder mechanics almost anywhere.
