Arm Crossover
Description
The arm crossover is a dynamic shoulder warm-up where you swing both arms out to the sides and then cross them in front of your chest, alternating which arm crosses on top. It warms up the chest, shoulders, and upper back through full range of motion. It is a staple drill before upper-body training.
