Many people have partners for jogging or swimming. Partners are good for motivation, accountability and to keep from getting bored. I personally do not get bored exercising. I am in the zone, I get creative, I think of kicking butt (my own or others', or I can read or watch television on cardiovascular equipment. But there is nothing wrong with having a patner. Just make sure to breath well and deeply if you are talking.
You can of course shoot some hoops, do calisthenics, run an obstacle course, dance, and more. Use your imagination.
