It's not the 1950's so we don't expect you to ignore all technology but trust us, put down that mixer and mix by hand so you can get a heavy duty kitchen workout. Manual cooking is great for your arms to strengthen and tone the muscles. And it doesn't take that much longer than using that automatic mixer!
With the bowel in one hand, tucked against your hip, use your other hand to mix the batter. This isn't a hard exercise and its not too complicated but trust us, within 30 seconds you will have to switch hands because you will be getting tired.
