I recently had a consultation with Jake Nemeroff, and I couldn’t be more impressed. Jake was professional, knowledgeable, and made the entire experience easy and enjoyable. The training has been top-notch, and I’ve already learned so much. I’m truly grateful to be part of such a supportive individual. Highly recommend working with Jake and this team!

Training with Kate at Core Progression has been an incredible experience! Since starting I feel stronger, my endurance has improved, and I feel more confident in the gym. Kate is super knowledgeable and really fun to work with. I highly recommend Core Progression to anyone looking to make real progress and enjoy the process.

Core Progression has truly changed my life. I have been working out there with an amazing trainer, Street, for the past four months and I’m the strongest I’ve ever been in my life and in about as good a shape as I’ve ever been. Street has specifically tailored my workouts to my goals and my ever changing needs, adapting and evolving those on a session by session basis. He always gives me “homework” to do outside of our sessions as well to maximize my efforts. I truly look forward to our sessions, we have fun together, and I’m getting better. If you’re looking to start your fitness journey off on the right foot in 2026, Core Progression Central Park and Street have to be your place and trainer.

I’ve worked with a lot of trainers over the years, and Kale is easily the most competent and effective of them. He’s motivating and supportive, and he pays close attention to what actually works for your body. I deal with some joint issues, and he consistently adjusted exercises so I could train safely while still making real progress.

The overall environment is also great. The space feels welcoming, and the other staff are super friendly and make a point to greet you by name. I always look forward to seeing the sweet pups that occasionally hang out, as well.

If you’re looking for a trainer who knows what he’s doing and takes the time to create a program that’s effective for you in an environment that’s approachable and friendly, I’d highly recommend Kale and Core Progression!

My daughter started coming here for speed/agility and strength training for soccer and loves it! She works with Jeff and Natalie and they are amazing with her!! Recently she started working with Jeff on nutrition and we have seen results from that as well! She has seen a big impact to her level of play and I would highly recommend coming here for any type of training/nutrition needs!

Casey C. - Northglenn, CO

Training at Core has been an amazing experience! Everyone is welcoming, professional, and genuinely supportive. After just one month of training with Joe, I already feel stronger and much more confident. The best recommendation I can give is that I would 100% recommend Core to my friends!

Dani S. - South Denver, CO

I highly recommend Matt for anyone serious about their fitness journey. His passion and knowledge are evident in every session. Since training with him, I feel significantly more energetic and empowered in my daily life. He is a dedicated professional who brings a perfect balance of challenge and support to the table.

We have had an incredible experience with Core Progression Personal Training over the past 6 months. My 13-year-old son has been training with Jayden, and the progress he has made is truly impressive.

Jayden is patient, encouraging, and knows exactly how to work with kids in a way that builds confidence as well as strength. My son has not only become noticeably stronger, but he’s also more athletic, coordinated, and motivated to stay active — which is huge at this age.

What I appreciate most is that Jayden makes the sessions fun while still challenging him and teaching proper form and technique. My son actually looks forward to going, which says everything.

If you’re looking for a safe, positive, and results-driven place for your child to build strength and athletic ability, I can’t recommend Core Progression and Jayden enough!

My one-year anniversary is coming up, and I couldn’t be happier with my experience at this gym. The support and encouragement I’ve received have been essential in keeping me motivated. Nick is not only a great guy but also an incredibly skilled trainer. I never imagined I’d be in such great shape in my forties! You should give them a try!
