TO KEEP BALANCE
The basal ganglia (sub-cortical structures of the brain involved in movement control) are quite old in evolutionary terms, therefore they are still tuned to tetrapod/quadruped movement.
When we initiate voluntary movement the basal ganglia "assume" that our arms (which used to be the first pair of legs, in a sense) should be moving as well.
More recent research suggests that it actually counters the turning torque as each leg pivots off centre..
For much much more info see the paper by Yu Li and partners at Liverpool university on movements related to Human Arm Swinging published 5th December 2000 in the journal of experimental Biology..
For a less taxing explanation there is a decent report from Cosmos at

Do cats have arms or legs, and how do they use them in their daily activities?
Cats have legs, not arms. They use their legs for walking, running, jumping, climbing, and balancing in their daily activities. Their front legs have flexible joints that allow them to groom themselves and catch prey, while their hind legs provide power for jumping and running.
Can you donate legs and arms?
Yes, it is possible to donate limbs in certain circumstances, such as through a medical institution for research or prosthetic development. However, the process is very rare and typically only done for specific medical purposes. It is not a common practice for individuals to donate limbs like they would other body parts.
What are the prime movers in a golf swing?

How can I maintain straight arms in my golf swing for better accuracy and power?
To maintain straight arms in your golf swing for better accuracy and power, focus on keeping your arms extended and relaxed throughout the swing. Avoid bending your elbows or wrists, and maintain a consistent arm position from backswing to follow-through. Practice proper posture and alignment to help keep your arms straight and improve your overall swing mechanics.
Why does your hands swing in opposite directions to your feet while walking?
answer: - to keep your body balance you can still walk with balance when your hands are in your pockets or doing anything else because hand swings don't affect much while walking but if you see runners, especially athletes, you will notice that they swing their hands.
