Generally, you can shake your arms, turn your waist, shake your legs, etc. To promote blood return and actively relax muscles. Walking slowly is also a good way. As for your calf swelling, it should only reflect the muscle group after exercise. Jogging won't make your calves bigger, but your feelings are only temporary. When you resume your rest, it will naturally disappear. If you are not sure, I suggest you measure your calf and exercise alone.
