Sometimes it's hard to get motivated to work out on your own. Things always come up in your schedule, and it's easy to skip exercising. One thing that helps me stay on track is when I make plans to work out with a friend. You can make it a once in a while type of thing, like planning a two-hour hike on a Saturday. Or you can make plans where you meet at your local yoga studio for a class once a week. If you need something more consistent then schedule something such as a walk before you both have to go to work in the mornings.
Having someone who's counting on you to be there makes it less likely that you'll skip it or put it off. It'll motivate you to go knowing your friend expects you to be there. Plus working out and being able to chat can make the time go by quickly, and it's so much more fun that you may actually forget you're even exercising.
