The Vikings were known for their love of meat and ale, but despite their reputation for overindulgence, they were incredibly fit and capable warriors. In fact, the ale they consumed was much weaker than modern beer and was often used as a source of hydration during their long voyages at sea.
The secret to their physical prowess was a lifestyle that blended hard manual labor with athletic pursuits. As a seafaring people, the Vikings spent much of their time fishing, hunting, and farming, giving them the energy and endurance they needed to thrive in their harsh environment. In their leisure time, they engaged in sports and competition, building strength, coordination, and endurance.
This combination of manual labor, athletic pursuits, and a diet rich in protein and fats, kept the Vikings in top physical condition, ready to face any challenge that lay ahead. So, while they may have enjoyed a good drink and meal, their active lifestyle was the key to their fitness and their ability to fight.
