WHY FIRST GUESS FITNESS

Kim Epstein
"I could not love it here more. Patrick and Justin are incredibly skilled and patient coaches. Butt kicked? Yes. But also so helpful for sustainable fitness"

FG Fitness is fantastic! The small class sizes ensure you get the attention you need, especially when it comes to form. Justin and Patrick are amazing coaches who run excellent classes and truly create a welcoming environment. The facility is well-managed, and everyone makes you feel at home. Highly recommend!

First Guess Fitness has been a great place for my strength fitness journey. Justin & Patrick do an awesome job balancing exercise, accountability, and fun (especially when Scout shows up!). They look out for your form, help you push yourselves to meet your goals, and keep class engaging.
