Pre-Workout Endurance Smoothie


• 2 cups coarsely chopped spinach • 2 cups filtered water • 1/4 cup frozen blueberries • 1 small raw beet, trimmed and chopped (about 1/3 cup) • 1 pear, cored and chopped • 1 stalk celery, chopped • 2 tablespoons ground chia seeds Optional: 1 teaspoon ground cinnamon

Wake up with this gluten-free, nutrient-rich, exercise-enhancing smoothie.

A number of studies have shown that the lowly beet is high in dietary nitrate, a natural substance that boosts the efficiency of working muscles, delays exhaustion, and improves overall exercise performance.

Not a beet fan? Chard, arugula, celery, and rhubarb are also high in dietary nitrates. Mix these vegetables into your morning smoothie for a high-octane endurance boost.

Makes: 1 serving
