From an exercise perspective this allows you to workout with your exercise buddy without ever leaving home. Just set your computer up so that the camera catches you at a good workout angle. Then call your friend and start the workout.
There have been studies on the use of Skype to motivate exercise. The results were extremely positive. The use of this simple tool resulted in a 93% attendance rate for exercise (IDEA Fitness Journal, 2016 March). That's high!!
If motivation is a problem, consider using Skype with your exercise pal. It could be just what you need to stay focused!
