What is the secret of Arnold Schwarzenegger,  Hollywood’s iconic action hero and former Mr Universe, staying strong, healthy and happy at the age of 77? It’s a plant-based diet and positive thinking that keeps Arnold fit as a fiddle, despite his advancing age. More than 70 per cent of Arnold’s food intake is vegetarian.

Arnold advocates for a predominantly plant-based diet, motivated both by personal health and environmental concerns.

In recent years, he has reduced his consumption of meat and dairy, turning to plant-based proteins and whole foods. His meals often include vegetables, grains, legumes, and plant-based meats.

He is not dogmatic—he occasionally eats animal products but encourages moderation. This pragmatic approach has helped him manage cholesterol, maintain lean muscle, and support heart health after undergoing heart surgery multiple times since the late 1990s.

Arnold promotes balance. He says: “I’m not 100% plant-based, but I have cut back on meat considerably. I feel healthier and my blood pressure and cholesterol are great.”

Perhaps the most crucial factor in Arnold’s enduring health is his unshakeable mindset. His life is a testament to the power of positive thinking, goal-setting, and resilience. From a poor Austrian village to global stardom as a bodybuilder, the Hollywood icon, and former Governor of California, Arnold has always used visualization, discipline, and self-belief as guiding tools.

As he grows older, he doesn’t dwell on decline. Instead, he views aging as a challenge to be managed with grace and strategy. “You can’t climb the ladder of success with your hands in your pockets,” he famously said—and that drive continues to shape his daily routines.

He’s open about the changes aging brings, such as losing muscle mass or requiring more recovery, but he adapts rather than surrenders. His mindset keeps him motivated and future-focused.

While most people his age have long retired from physical challenges, Arnold continues to train, advocate for health, and inspire millions through his online presence, activism, and public appearances.

Arnold’s journey with fitness began in his early teens. As a young boy growing up in post-war Austria, he discovered bodybuilding as a way to break free from his modest beginnings. That initial spark became a lifelong flame. Decades later, although he no longer lifts to compete, Arnold remains committed to a consistent, age-appropriate exercise regime.

Today, his workouts focus less on heavy weights and more on maintaining mobility, strength, and heart health. In interviews and social media posts, Arnold has shared that he exercises every morning—often starting with cycling or walking, followed by resistance training adapted to his body’s current needs. Unlike in his competitive years, he now emphasises moderation and form over pushing limits.

His message is clear: staying active isn’t about chasing old glory—it’s about quality of life. As he once said, “Training gives us an outlet for suppressed energies created by stress and thus tones the spirit just as exercise conditions the body.”

Beyond the gym and kitchen, Arnold’s sense of purpose keeps him youthful. Retirement is not in his vocabulary. He continues to act, write, speak, and advocate. His newsletter, The Pump Daily, shares fitness and wellness tips with a global audience. He supports environmental causes and after-school programs. He constantly seeks to educate and uplift others.

Psychologists have long linked purpose to longevity. Arnold embodies this principle. Whether through public service, climate activism, or mentoring younger generations, he continues to find meaning in service. This, in turn, fuels his health. His days are full, and his motivation stems from helping others achieve their goals—just as he achieved his.

A key part of Arnold’s sustained health is his ability to adapt. He doesn’t cling to his Mr. Olympia persona in an unrealistic way. Instead, he’s embraced the wisdom of age. He has dealt with health challenges—most notably, open-heart surgery—with resilience and transparency.

Rather than pushing through pain or trying to defy nature, Arnold listens to his body. He encourages others to do the same: to exercise wisely, avoid injury, and think long-term. Arnold reveals: “I adjust my workouts for my age. I don’t try to lift what I used to. I do more biking, stretching, and bodyweight exercises. It’s about staying active and enjoying life.”

Another factor in Arnold’s well-being is his strong social life and sense of humour. He maintains friendships, engages with fans, and shares light hearted content, including clips with his miniature donkey and pony. Joy, connection, and laughter are part of his daily medicine.

A happy outlook can lower stress hormones, reduce inflammation, and improve heart health. Arnold’s playful attitude, combined with his fierce discipline, creates a well-rounded life.

Arnold’s life offers a blueprint for aging, not as a decline, but as an evolution.

While genetics may have helped him at the start, it’s his choices that keep him thriving. For those seeking to remain vital with age, Arnold’s example is clear: train smart, eat clean, stay positive, and never stop contributing.
