Don't just take our word for it...

Our clients love us (and we love them back)

Matt is so knowledgeable and fun to train with! His enthusiasm and encouragement are propelling my journey to reaching my physical goals!

It's been hard for me the last few years trying to get back in shape myself. So I decided to grab some accountability. I just didn't realize at the time I was getting one of the best trainers around! Matts knowledgable, experienced and a hard worker. He truly takes time to care about his clients success in all phases of their life, health, work, family. Highly recommend this awesome trainer'

Matt is awesome. He has such a strong knowledge of the muscular system, and is able to identify the root cause of pain in the body. I came to him after two chiropractors and an MRI couldn't figure out what was causing me so much pain. He not only identified it, but has helped to drastically improve my pain levels after just a couple of weeks. Thank you so much Matt!!

I wandered into The Fitness Lab after two cervical spine fusions spaced 5 months apart. I was in decent shape before my degenerative disc disease and osteoarthritis took hold, however due to the pain and partial paralysis I did not exercise at all for nearly a year. Needless to say, I sought help to literally get on my feet again. Matt Oster took me in like shelter in a storm, and with his extraordinary patience and expertise, I've been able to exercise with little to no pain, with benefits far-reaching beyond the gym. Under his watchful and caring eye, I am confident I can perform movements with accuracy and efficiency I have never before been able to achieve. With the addition of Bill to The Fitness Lab team, I now have one of the most experienced and knowledgeable physical therapists in the Denver Metro area in my personal health arsenal. Matt and Bill are extremely competent and amazing, and manage to keep a positive (at times, hilariously funny) atmosphere that is a pleasure to experience. I'm blessed to know them. Thanks, guys!

I've known Matt since he was a high school student, he's been doing some remote training for me for the past year as I live about an hour away. Today I took my 14 year old son down for an evaluation, he's been having quite a bit of knee pain during basketball season and I thought he would benefit from some strength conditioning. I was actually profoundly impressed with Matt's psychological knowledge and assessment of my son. He observed that Aidan was a bit misaligned and and as a result putting too much pressure on one knee. After a few 'adjustments' Aidan was already showing more balance in his movements. I'm so thankful we saw Matt early in the process as the kid is entering high school and the conditioning and training process could actually do some damage if we didn't work on some basics with Matt first. Well done!
