I, too, LOATHE exercise. I struggle every day with working out, and I literally have to force myself to do it. But, luckily, I am an organizational junkie. So this is what I do:
Write it down. In my planner. With a time. Like so:
6:00pm-7:00pm - Workout (The Firm: Super Cardio)
Treat it like a "real" commitment, because it is! If you had a meeting at work, scheduled for a certain time, you would go even if you didn't want to, right? Or if you have a class scheduled at a certain time, you would go even if you didn't want to, right? That's how I think of exercising...I don't want to do it, but it's an appointment to make sure that my body stays healthy and that I look the way I want. To me that's just as important as a school or work commitment. Of course, I'm a complete slave to my planner and my to-do lists, so this method might not work for everyone...but it's worth a shot!
Good luck on sticking with it!
