Keep well hydrated, drink a few sips f water whenever you feel it's necessary. For 60+ minute workouts, drink water or sports drinks with electrolytes in them.
Make sure you are getting enough potassium in your diet. Bananas can be a quick and easy way to do this!
Also make sure you are getting enough calcium and magnesium, adding small amounts of mineral salt (Celtic or sea salt) to your food can help.
