Spartans took pain and made it their friend. The Spartan workout exercises some major muscle groups to give you the total warrior feeling when you move. The additional load of dumbbells, or any other weight you can safely use instead of them, makes this workout one to use when you aim to level up. For a no-equipment total-body strength workout try Spartan.
Extra Credit: Use 10 lb+ (5 kg+) dumbbells minimum.
