For many people, fitness is more than just a hobby—it’s a lifestyle. Trainer Eric North—who goes by the Happiness Warrior online— is one of these people. At 61, he trains regularly and is in great physical condition.
North is an advocate for any and all movement. “Regular physical activity reduces stress, improves mood and boosts cognitive function, all of which contribute to a more positive outlook and enhanced decision-making abilities,” he says.
