Hey Pook, I also have friends that I excercise with that will bail on me at times. The thing that keeps me going is the knowledge that I'm doing something good for me...and the fact that it'll be over before I know it. 20-30 minutes fly by and the way I feel afterwards is great! Plus this time I'm taking it slow and I've noticed that I'm losing FASTER because of it. My goal is to lose weight THEN work on cardio stamina. before I had it all backwards and I was working TOO hard and seeing little results. So start slow....that's easy to get motivated about, and I can guarantee that when the scale starts moving down you WILL be MORE motivated! Worked for me
