what should you eat before walking
You should have a light snack about 30 minutes before any exercise. Fruit and yogurt is always a good choice, but you should definitely eat something or you will not have the energy to do very much. Also, after you are finished, a small (12 oz or so) smoothie is a good replenishment for your muscles. Make sure the smoothie is pretty light, though, just fruit, water, ice, and protein powder.
