    I’ve been attending classes with Erik for a few weeks now and I have a feeling I will be for a long time lol. I was nervous about attending a class but everyone was very kind and welcoming, had a blast!

    UBX Old Greenwich is great! Fast moving and fun! Erik is a fantastic coach and stays on you so you get the best workout! All the coaches are great though. Can’t go wrong. And I love that I can show up whenever I want without having to worry if I signed up or not! No wait lists or last-minute cancel fees to worry about. It’s a great concept!! Love it!

    UBX quickly became my favorite workout. Eric and the rest of the team at UBX are so great. I love not worrying about class start times and just showing up whenever I am able, while still knowing I will have the motivation and knowledge of a trainer there.
