My Approach to Fitness: Strength, Longevity & Real-Life Results

My training philosophy is built around balance. I focus on the five key pillars of fitness: strength, endurance, mobility, nutrition, and recovery. Each of these areas plays an essential role in helping you move better, feel stronger, and stay active for the long haul.

At the heart of my method is functional fitness—training that improves the way you move and perform in daily life. As someone who provides functional fitness in San Diego, I tailor each program to match your goals and physical needs, ensuring your workouts are both effective and sustainable.

I specialize in longevity training for adults over 40, with a strong emphasis on joint health, injury prevention, and the connective tissue work that supports pain-free movement. Whether you’re looking to gain strength, improve flexibility, or simply stay independent and active as you age, I’ll help you build a body that supports a strong, healthy lifestyle.

To keep training effective and engaging, I use a variety of customized tools and modalities based on your goals, fitness level, and preferences:

  • Bodyweight exercises

  • Free weights

  • Resistance bands

  • Kettlebells

  • Balance and coordination tools

  • Cardio equipment

  • Mobility and flexibility aids

Together, we’ll build a strong, resilient body that supports a healthy, active, and vibrant life—for decades to come.
