Boost Your Workout Performance And Results Because Nutrition Matters. Juicing is a great way to get your body pumped and primed for a lengthy workout session. When you juice, you cram loads of essential nutrients into one glass that will power your workout and improve your results. Besides the important health benefits, key plant nutrients give you energy so you perform at your best in your workouts and get the most out of your exercise efforts. Because a lot of us don’t like eating whole fruit and vegetables, we struggle to get our fill of the essential micro-nutrients. Micro-nutrients are gems of nature for our bodies and minds. Without them, our bodies aren’t ready for a workout.
