I have always hated to run too. (I'll even admit to cheating when we had to run a mile and a half in high school! I hated running that much.)

I still don't like running all that much but is is one of the best ways to get your heartrate up. I started out on a treadmill by walking briskly for 20 minutes. After that became easier I then started a small jog every four minutes. Now I jog every two minutes for almost a minute. All you need is 20 minutes to get your metabolism going.

I'd suggest doing what you enjoy - but do it at the level you're capable of. There's no shame in listening to your body and taking it easier until you build your stamina back up again.

Good luck!
