Navy Veteran Shares Keys to Staying Fit as You Age
Mike McCastle, a U.S. Navy veteran from Las Vegas, has made headlines by setting seven world records, one of which includes walking lunges for over four miles across Utah’s Bonneville Salt Flats. At 38 years old, he believes that the secrets to staying strong and healthy as we age lie in consistency, recovery, and smart training.
For McCastle, participating in these challenges goes beyond mere records. “Every step taught my son about grit, purpose, and finishing what you start,” he shared. “Pain became information, not something to fear.” His journey towards health and fitness was shaped by experiences during his Navy service, where multiple knee surgeries ended his military career.
Driven by a desire to raise awareness for causes like Parkinson’s disease and veterans’ mental health—issues that affected his late father—McCastle initiated the 12 Labors Project, a series of endurance challenges he’s undertaken over the past decade.
Tips for Staying Fit
Here are McCastle’s top tips for maintaining health and resilience at any age:
1. Start Small
Many people make the mistake of overexerting themselves at the beginning. McCastle advises starting with simple actions. “A 10- to 15-minute walk daily, a few push-ups, and drinking more water can lead to real changes,” he said. Consistency is the key.
2. Emphasize Strength Training
McCastle highlights the importance of building muscle, especially as we get older. “Muscle helps improve balance, joint stability, and bone health,” he explained. He recommends doing strength training two to three times a week along with daily walks.
3. Make Movement a Habit
McCastle encourages people to incorporate physical activity into their daily lives. His routine includes full-body workouts alongside conditioning exercises like sprints or hikes. He prioritizes mobility, making sure to stay active even on rest days by walking with his son.
4. Prioritize Recovery
After enduring physical challenges, McCastle recognizes the importance of recovery. “Sleep, hydration, and mobility are critical,” he noted. His routine includes active recovery methods like walking and mobility exercises, plus mental relaxation through journaling.
5. Simplify Nutrition
When it comes to eating, McCastle advocates for a simple approach with whole foods. He recommends including protein at every meal and staying hydrated while minimizing processed sugars. “Focus on habits you can maintain rather than strict diets,” he advised.
Overall, McCastle believes that the goal of fitness is longevity. “Strength is about building something that lasts, not breaking yourself down,” he said. His journey illustrates that with the right mindset and practices, staying healthy as we age is attainable for everyone.
