Arnold Schwarzenegger regularly trains at Gold’s Gym despite being 76. Although the seven-time Olympia-winning physique that he built in his youth is long behind him, the bodybuilding legend is still fit enough to perform stunts on screen. So, who better to advise you about longevity than the Austrian Oak?

The former Mr. Universe explained that while trends like biohacking have gained popularity, the key to longevity is simplicity. Arnold Schwarzenegger explained that you can age gracefully by simply exercising. Research says, “Maintaining strength and building muscle is one of the best investments you can make if you want to live to old age,” wrote Arnie.

The Terminator star revealed that the study came to this conclusion after collecting data for 45 years. Fortunately, you don’t have to train too hard to experience these benefits. “You can unlock the benefits of strength training with as little as two to three workouts per week,” Arnold Schwarzenegger wrote in his newsletter.

Arnie also referenced other studies that found the average person starts losing about 8% of their muscle each decade after reaching 40. Although our metabolism stays about the same until 60, how we age depends on our exercise, sleeping, and eating habits. These changes are the same in men and women.

However, strength training consistently makes a massive difference. The final study Schwarzenegger, highlighted “followed menopausal women for six years, and those who consistently performed resistance training did not lose muscle, gain fat, or see any changes in their metabolism.” So what kind of training should you follow?

Arnold Schwarzenegger has you covered

The Austrian Oak’s goal has been to make exercising accessible and simple. Recently, the bodybuilding legend released a 115-page workout guide for free. The training guide condenses 60 years of experience that Arnold Schwarzenegger earned throughout his career. It contains training programs for all levels.

Schwarzenegger’s Get Back in Shape has something for everyone, whether you’re looking to get into exercise and don’t have access to the gym or an advanced lifter with years of experience. The bodybuilder also recently spoke about the necessity of cardio and explained that it should be incorporated with strength training for better cardiovascular health.

In today’s connected world, there’s no shortage of fads that make lofty promises. However, Arnold Schwarzenegger makes the science-backed argument that exercise is one of the best tools to age gracefully.
