Watermelon Juice with lemon
Watermelon's high water content, antioxidants, and amino acids may make for a better workout. It's also high in potassium, a mineral that could cut down on cramps at the gym. You can sip watermelon juice after you sweat, too. Doing so could help prevent muscle soreness, as long as you don't push yourself too hard
Watermelon is around 90% water and also provides electrolytes, such as potassium.
