10. You're Letting the Machines Take Over
Plenty of modern luxuries save us time while robbing us of calorie-burning opportunities. Scrubbing the dishes by hand (versus letting the dishwasher do the work) burns approximately 160 calories in a half hour, according to Fitday.com. Instead of using those blenders, automatic mixers, and electric can openers, do the work manually. You could even forsake your dryer and use a good, old-fashioned clothesline; just carrying a full laundry basket from the laundry room to the yard and back upstairs can burn up to 100 calories. You can keep using the vacuum, but consider doing half the job with one hand then switching to the other for a full arm "workout."
