For me, best to do it at night, looking out a drapeless window. You shadow swing into your reflection.
Also, late afternoons, looking at your shadow.
Usually 5 minutes completely tires me out.
LOL at the 5 minutes part.
But I'm in such bad shape that I understand.
If you have the room, you can make it into good exercise as Lee says. Do a split step move to the side, swing, and then recover back for another split step. It's combining off court aerobics with off court tennis training.
