  • Little did I know that hiring a trainer at NRG Lab would change my life! My trainer has a contagious enthusiasm and I cannot help but feel energized (even when I don’t want to). I now climb stairs and get off the floor after playing with my grandchildren. I never thought I would be that person who says “I cannot wait to get the gym”. Because NRG Lab is far more than a gym, the community atmosphere here and adding personal training has made all the difference.

  • When I started with a trainer at NRG Lab, I was out of shape, overweight and had very low confidence. I got winded easily and was nervous to work out in front of anyone else. Training at NRG Lab has been a life changing experience! My trainer has opened my eyes to the things that I can do and has helped me accomplish my goals. I am 4 sizes smaller and now see myself as capable and strong.

  • Seeking a more targeted approach to our fitness goals, we decided to try personal training. Even though we had different goals, we were able to train together as a couple. Our trainer pushes to our limits each session, always upping the ante and mixing things up. We are now in the best fitness of our lives!
