The so-called Palaeolithic diet, based on the lean meat, fruit and veggies that our Stone Age ancestors ate, is now being teamed with a Palaeolithic workout. Designed to tone muscles and promote wellness, it emulates the activities of Stone Age hunter-gatherers. The regime involves a wide range of exercise such as sprinting, carrying, lifting, throwing, balancing and even crawling. Proponents of the system believe this variety of movement provides a more rounded, natural workout than more focused exercises such as running, cycling or weight training. All you need is a stick, boulder or club!
