Doing housework can be a real workout and a new study by Marigold gloves has revealed that you are burning up to 200 calories just by doing the dishes for 30 minutes, twice a day. If you have a big family and no dishwasher, you’ll easily spend that time washing up. Even if you have a dishwasher, why not don your Marigolds and try washing up manually every now and then instead, to burn a few extra calories?
