Its good to have a cordless phone and keep moving around while talking. If you have to stand at a spot, you may exercise leg muscles by marching or rise to tip toes. Wash and iron your clothes. Mow the lawn. If you have power mover change it for a push model.
Gardening is a very good exercise.
Roller skating, jump rope are very good exercise. Swim or a bike ride or a row boat outing on a lake. Sorry, your browser doesn't suppor Java.
