If somebody told you that there was a magic pill you could take that would allow you to lose weight, while gaining health & energy, would you do it?
There is: it's called exercise. Incorporating purposeful movement into my daily routine has been the single most important and life-changing thing I've done. No more whining about not having equipment, the right shoes, or knees that will carry around nearly 300 lbs without a complaint. You don't need all that stuff, any of it really, to burn calories and make a difference in your life.
Honestly, you don't even have to get up off the couch. But, you DO have to move. Every day. Whether or not you "feel like it."
Any time I miss a day, I feel grumpy and miserable. At first I may not even realize why I'm so moody. Then I tell myself I will walk purposefully for 10 minutes minimum and I end up feeling better and weighing less. If my knees ache, I do floor exercises or stretching. Some days I tell myself that I only have to do the warm-up session of a Richard Simmons tape. By the time we're stretched and ready, I'm willing to do more.
So whaddya say? You like the magic pill? It's free! C'mon, everybody's doing it!
