“My wife and I are in our mid-sixties. While we both are physically active, we had never used a personal trainer before. Both of us are so pleased that we worked with John Starr. Over the course of a year, he helped both of us develop greater flexibility, balance, and strength, while also addressing specific issues (e.g., shoulder pain, plantar fasciitis). We recommend John to anyone looking to improve their overall fitness.”

Building strength that lasts — for life, sport, and everything in between.

  • Your training should help you live stronger, not just lift heavier. Together, we’ll build strength you can rely on, so your body supports everything you love doing: from hiking the Flatirons to chasing your kids around the yard. Every workout is designed to improve stability, balance, and long-term performance.

  • Mobility is what keeps you fluid and pain-free — it’s the key to staying active for life. Through intentional movement, corrective exercise, and physical therapy-inspired recovery techniques, we’ll keep your joints healthy and your body moving the way it’s meant to

  • Injury prevention starts with rest and repair. From mindful stretching to recovery-focused sessions, we’ll make sure your body gets what it needs to heal, rebuild, and come back even stronger — so you can stay consistent, not sidelined.
