It’s worth knowing that eight of the best marathon runners in the world not only come from Ethiopia, but the same village! They’re powered by nature’s live, water-rich foods; so fresh fruit, live yogurt, and green leafy vegetables. At which point, we highly recommend consuming genuine natural carbohydrates in the form of fruits and vegetables in smoothie form.

This baby is the king of juices for pre and post cardio workout. A team at the University of Exeter found that nitrate contained in beetroot leads to a reduction in oxygen uptake – making exercise less tiring. A study in the Journal of Applied Physiology suggests the effect is greater than that which can be achieved by regular training. The study’s researcher Professor Andy Jones – an adviser to top UK athlete Paula Radcliffe – said: “These effects cannot be achieved by any other known means, including training”
