You can still exercise while doing the cleanse, but we suggest only engaging in the light cardio instead of any intense workouts.  Because you're on an adjusted diet that consists of mainly fruits and vegetables, you may burn through the foods faster as opposed to when you workout while consuming carbs or starchy foods.  You can drink Green Tea for a boost of energy or consume raw foods that provides a natural source of energy.  Foods that provide you with more energy include bananas, spinach, citrus fruits like grapefruits and oranges, apples, almonds and lemons.
