I had no intention to exercise. Exercise was boring and very painful.
After about 2 months and 60+ pounds I felt lighter and wanted to try moving around more. I started walking about more. Went down on the strip, malls, museums, aquariums. Just around and people watching. Eventually we were walking about 8 miles several times a week. But exercise? No way.
After about 10 months and 200+ pounds, I just felt like I had and abundance of energy. Almost floating, it seemed. I thought I'd see if I could run. I bought "Idiots guide to running" which had a program to run 30 minutes in 30 days, and managed to complete it. I listened to audio books to pass the time. But exercise? No way.
Month 13 and 250+ pounds down, I was still running. Listening to the Dark Tower (7 books), so runs got longer until I was running 90 miles per week. Over the next year I ran 5 marathons.
I never did exercise. Exercise is boring and an obligation. I didn't have surgery to live on a diet and do things I never wanted or enjoyed doing.
Walking, then running, was a joy.
Do you.
