When you are planning to exercise, you should ensure that you start in a well hydrated state. To ensure you are well hydrated, aim to drink 8 glasses of water a day. Then, during exercise your fluid intake should match your fluid outlay. A good tip is to take 2 to 3 sips of Hydralyte’s electrolyte solution while performing sustained moderate to vigorous physical activity – this will help to prevent potential dehydration.
