Our clients love us (and we love them back)

I highly recommend Matt as a trainer. Always punctual, always has new exercises and routines to keep things interesting, packs a LOT into each training session, and is a fun person who loves what he does. I also appreciate his nutritional advise and counseling, this wasn't an aspect I expected but with his guidance in the gym and outside the gym, it has made all the difference in the world. He has what it takes to get you to a healthier, stronger, and happier place!

Awesome way to get out of your old training habits that may be holding back your gains. Matt made my day today, what an awesome workout that targeted muscles that I have been neglecting in my body building and HIT cycle training. I can't wait for Monday AM workout.

Talented, personable, committed, results driven, a pleasure to work with. All qualities you need for your personal training. Highly recommend Matt at The Fitness LAB.

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!

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!!
