“Joining a couple of years ago was one of the best decisions I’ve made. I was always intimidated in conventional gyms and to be honest had absolutely no clue what I was doing! However with GU, it feels like a personal training session every time with small classes, one-to-one feedback and constantly varied cycles that have helped make me fitter and stronger than ever. Not to mention it has a great community aspect with friendly members and regular social events.” — Kate
