Chest


Chest / Beginner / Isolation (single joint)
A cable isolation exercise for the chest, with the front delts assisting.
Why it hurts: The shoulder is dragged into end-range extension, straining the front of the joint.
✓ Instead: Start with the hands in line with the chest and keep the shoulder blades back.
Why it hurts: The shoulders roll in and the chest stops working.
✓ Instead: Stand tall, lead with the hands in an arc and keep the chest proud.
