what makes us different

Not a Gym. Not a Clinic. A Performance Facility.

A young man with dark wavy hair sitting at a desk, using a laptop. He has his hands clasped together on his chest and is wearing a T-shirt, necklaces, and bracelets. The background shows an indoor setting with a doorway and a shelf.

We don’t sell memberships and leave you to figure it out. You get clear direction, structure, and support from day one.

No Guesswork

No generic protocols here. Everything we do is built around your body, your goals, and your full picture.

Fully Personalized

Elite Training

We combine the precision of elite coaching and modern medicine, scaled to fit real life.

Built for Long-Term Performance

Integrated Training, Coaching, and Hormone Optimization

Most People Aren’t Failing. They’re Guessing.

Training harder doesn’t always fix the problem. Eating “clean” doesn’t guarantee progress. And no amount of motivation can overcome unmanaged stress, poor recovery, or declining hormones.

Most people are following fragmented advice, workouts from one place, nutrition from another, and medical care completely disconnected.

That’s why progress stalls.

We Treat the Body as a System

At X365, everything works together. Training, coaching, recovery, diagnostics, and, when appropriate, hormone optimization.

Nothing is random. Nothing is generic.

A woman with long blonde hair, wearing a black baseball cap, black sports bra, and black leggings, is lifting a kettlebell in a gym. She is squatting on a black exercise platform with a focused expression. The gym has black ceiling beams, fluorescent lights, and various cardio machines, weights, and American flags in the background.

Intelligent strength and conditioning designed to build resilience, preserve joints, and support long-term capacity, not exhaustion.
Individualized guidance that accounts for lifestyle, stress, sleep, and recovery, not just workouts.
Objective data to remove guesswork and guide decisions.
Medically guided support to restore balance when lifestyle alone isn’t enough.

The x365 method

Our method is for you if:

You are motivated and want to stay strong, consistent, and capable.
You feel like you’re “doing everything right” but not getting results.
You want expert guidance instead of trends or extremes.
You care about long-term health as much as aesthetics.
You prefer a calm, professional environment over chaos.

A woman with a bun hairstyle wearing a blue tank top is sitting in a black chair, appears to be in a therapy session. A man with dark, curly hair, wearing a black t-shirt, white sneakers, and jewelry is sitting across from her, speaking and gesturing with his hands. They are in a room with a white wall, a desk with a laptop, water bottle, and office supplies, and a modern, spherical lamp.

Hormone optimization

Hormone therapy isn’t about shortcuts.

It’s about restoring what time, stress, and lifestyle have disrupted. Based on labs, symptoms, and medical oversight.

At X365, hormone optimization supports training, recovery, cognition, and overall health—and is only used when appropriate for the individual.

“This is the best gym in the area hands down. Its a smaller private gym, locally owned with a good vibe. It has nice equipment, a great no douchebag policy and awesome trainers. I train with Ron Lindsay and am very happy with his in-depth knowledge about metabolism, body reset, and obviously his knowledge on proper execution of exercises. Several of my friends and family now trains with him after hearing what I have to say.”
– Levi D.
“After cancelling all my gym memberships due to COVID, I was looking for a small, clean gym that I felt safe in with all the equipment I wanted. I researched all the gyms in the area and chose 365 fitness and it was exactly what I was looking for. Knowledgeable staff, clean facility, and all the equipment to get any workout in. The best part is that you can access the gym 24/7 so you can go whenever the workout bug gets you! I would recommend 365 fitness for sure!”

“My experience at X365 has literally been life changing. Nick and Ron keep X365 clean and well-equipped and welcoming. It’s been said that a good coach can help you win the game, but a great coach can change your life. As my personal trainer, Ron has changed my life.”
– Joseph B.
“Nick is a great personal trainer, and I love each of our sessions. He is super passionate, inspiring and focused on my personal goals. He educates and guides me on how to reach my goals in the best/healthiest way possible. Not only is he a great personal trainer, but also has incredible input and advice. The gym is in a great location, and is always very clean. If you’re looking for a great personal trainer, this is the place to find one! Would definitely recommend!”
