 We asked our members, what's your favorite thing about the Summit Athletic Club? Here's what they have to say. My favorite thing at Summit Athletic Club has got to be the healthy postures class. You can always jump into a class or a workout that maybe you haven't done before. You feel comfortable that you're being taught by instructors that know what they're doing, that are going to keep you safe, but then also challenge you, take you to that next level.
