If you want to keep fit then what do you do if you don't go to the gym but have a sedentary job?
1. Wash the car - a three-hour vac, wash, dry and wax will consume around the same number of calories as a heavy gym session.
2. Energetic 'ladies and gentlemen'...erm, you know what I mean. Easily consumes 500-1000 calories.
3. Go shopping for a couple of hours. Walking a couple of miles will probably burn off 200-300 calories.
