We may not give it much thought, but fidgeting burns calories.
It is considered a non-exercise activity, and it can burn an additional 300-800 calories a day.
It is put in the same category as stretching, changing posture, or getting up from a chair.
So, when you find yourself waiting in line, stuck in traffic, or watching TV commercials, think of it as an opportunity for exercising, and do some fidgeting.
Any kind of movement counts, and keeping those muscles moving is the important thing.
