Here is a homemade “Sports Drink”, this is an excellent option instead of sugary and artificial drinks:

1 Quart Spring Water

Juice of 2 Lemons

1/3 cup Raw Honey

1/2 TSP Sea Salt

This homemade sports drink will provide you with water to hydrate yourself,  with lemon juice that will give you vitamin C, with honey that will give you sugar for power and endurance, and with salt that will help regulate fluid balance and will promote proper muscle function.
