If you find that some days make it hard to get in that run, walk or treadmill routine, try a good dose of housework instead and lose a chunk of calories anyway.

According to this source, regular cleaning activities like washing dishes and mopping the floor (among others) burned about 50,000 calories per year. Wow!

In other words, standard household chores are equivalent to walking more than 22 miles each and every year. It's something we have to do anyway, so instead of having the spouse or kids (or housecleaner) clean that house, do it yourself and get some calorie burning in there.
