I heard about the watermelon juice from the Gracies in many articles and videos. So I decided to give it a try after finding a massive watermelon for 5$ at my local veggies and fruits shop. It tastes awesome and I did not add anything else. It was very sweet and I might have to dilute it with some ice block or maybe a squeeze of lime. Some of the benefits: 1. It soothes sore muscles. 2. It helps heart health. 3. It could be a natural Viagra. 4. It's rich in vitamins and minerals, but low in calories. 5. It could even combat cancer. see: http://news.nationalgeographic.com/news/2013/08/130820-watermelon-nutrition-health-food-science/ http://www.fatsecret.com/calories-nutrition/generic/watermelon-juice
