I just wanted to share my personal experience (for what it's worth) - I've been a Sparkpeople member for many years - and I believe the reason I'm still here working on losing weight, is because I tried to use just part of the program. I, too thought my normal activities were enough. But I'm back again with the Spark Solution and think that the whole program is a big key to its success. The biggest lesson I think I have learned is that your body adjusts to your normal everyday activities so they stop being beneficial as far as weight loss is concerned. "Switching things up" is one of the keys to success in an exercise program - so I humbly suggest that you DO add just 10 minutes a day of an exercise your body is NOT used to. If you already walk 10,000 steps (yay!) do something like push-ups, curls, plank, (things you can do on a yoga mat) - and GOOD LUCK!
