What Clients Say

  • Kate Montgomery

    I used to be plagued with a reoccurring knee injury, but since taking on the strength training plan Eric and Mike offered me, I have been completely injury-free–despite more doubling the distance I run per week.

  • De McNeil

    Great Bay Strength pushes me out of my comfort zone and focuses on what I can do versus what I can’t do, and I’m pretty amazed at what I can do!

  • Tom Haines

    Eric, Mike, and all the coaches support the goals I bring in the door and push me to reach for new ones. They care about the hard work of fitness and the fun of community. I’ve found both at GBSC.
