Personalized training, accountability, and longevity-focused programs to help you move pain-free and stay strong for life. Functional Idaho Strength & Mobility for Longevity (formerly Jack City Fitness) is Boise’s results-focused coaching gym for people who want more than a workout — they want their life back. If you’re tired of starting over…
If your body feels stiff, beat up, or “not like it use
d to”…
If you’re busy, stressed, and don’t have time to waste guessing what to do…
You’re in the right place. We believe an “athlete” is anyone with a goal — fat loss, building real strength, improving performance, moving with less restriction, rebuilding after setbacks, or simply staying capable for the long run. You just need a reason, and a willingness to show up. This isn’t a place where you pay to “access equipment” and hope motivation holds. We built Functional Idaho around a Partnership model — professional coaching + real accountability — because your time is valuable and your health is too important to leave to chance. What it feels like to train here:
You walk in and you’re not invisible. You’re guided. You know exactly what to do today — and why it matters for your goals. You leave feeling proud, clear-headed, and more confident than when you arrived. That momentum carries into your work, your family, and the way you show up in the world. SERVICES (built for real people with real schedules):
• Personal Training (1:1 coaching and customized programming)
• Small Group Classes (community + coaching + fun) including options like Elite Fitness, Bodyweight Bootcamp, Olympic Weightlifting, Kickboxing, Flow Fitness, Elite Movement, and more
• Nutritional Counseling + Meal Planning (simple, sustainable habits — not crash diets)
• Online Partnership (personalized training and accountability from anywhere)
• 24/7 Gym Access + serious amenities (train on your time, not someone else’s)
• Assessments that remove the guesswork (InBody + movement assessment options)
WHY THIS SAVES YOU TIME:
Because you’re not wandering the gym, Googling workouts, or restarting every Monday. You get a plan. A progression. A standard. And you can train when it actually fits your life — early mornings, lunch breaks, late nights, or whenever your schedule finally opens up. WHY THIS SAVES YOU MONEY:
Because wasted time is expensive. So are unused memberships. So is buying equipment you don’t use. So is jumping from program to program and never getting traction. We help you invest in the one thing that changes everything: consistent action with expert guidance. If you’re ready for strength that shows up in daily life… mobility that keeps you doing what you love… and accountability that turns “someday” into real progress — book a free consultation, come take a tour, and let’s build the next version of you. Functional Idaho — Strength. Mobility. Longevity.
