Helping adults 40+ move better, feel stronger, and stay out of pain—one personalized plan at a time.

I’m Kyle Hildebrandt, founder of You First Fitness in Littleton, CO. I specialize in helping adults 40+ reduce pain, improve movement, and build lasting strength through corrective exercise and mobility-based training.

My journey started in high school, lifting weights in my best friend’s garage alongside his dad—a former Air Force powerlifter. I wasn’t chasing big muscles, but I was hooked on how the body worked. That early curiosity led me down a path of studying movement, biomechanics, and long-term health.

Over the past decade, I’ve worked alongside physical therapists, chiropractors, and rehab professionals to create a coaching approach that bridges the gap between rehab and real-life strength.

My clients often tell me they:

Move with less pain and more freedom

Regain strength and confidence they thought was gone

Finally stick to a plan that fits their body and lifestyle

I offer in-person sessions at my private studio in Littleton and hybrid/online coaching for those seeking structure and flexibility.

Ready to feel better in your body?

Meet Kyle’s Clients

Lynne B

63 yr old, CPA badass, musical and wine lover
My husband and I work out with Kyle. We have very different goals and workout styles. He is able to put together a workout that meets both of our needs. We have worked out with Kyle while having knee replacements. I think we have recovered faster and we were more pain free and active after our surgery than all of our friends.
Ryan L

17 yr old STEM genius and squat rack master
I used to be really bad about consistency in my workouts because I always tried to push it off and I never felt like I really knew what I was doing. Working with Kyle has been great since I can’t procrastinate coming to a scheduled session. I feel like I know what I’m working on with Kyle there to help guide me, and overall enjoy my time working out in a nice easy atmosphere. I joined a search and rescue team when I was just starting as a sophomore in high school and I used to worry about my strength in hiking, carrying people, and lots of other physically demanding tasks. After working with Kyle, I feel so much more confident in my ability to help people, which makes all the difference when I’m actually out in the field searching.
Lara B

49 yr old small business owner and creator of beautiful jewelry
Kyle believed in my ability to get in a better place physically even when I had doubts. He crafted a plan that met my needs and was easy to build on as I got stronger. He provided encouragement and compassion along the way! I know that Kyle is in my corner and actually cares about my health and well being!
Aaron N

Pianist and professor in real life, moonlights as an avid hiker
Kyle listens to your concerns and goals and considers them in the workouts he chooses. After working out with him for three months it is clear he has a long term vision. I look forward to continuing my training with him.
Rhonda M

57 yr old, Colorado local and Costa Rican snowbird for half of the year
I love the personal attention Kyle gives me. The workouts change depending on how I am feeling and my goals yet he makes sure they are challenging and fun. I have come to see my workouts with Your Time to truly be that; my time to be the best I can be.
Douglas H

Bridge master and 10,000 steps a day conqueror
Kyle is very knowledgeable and is able to work around any of my disabilities. He is also very personable and a joy to work out with. I don’t need a therapist because Kyle is a good listener!
