  • I love that the trainers are energetic and excited and push you to work out but without shaming or embarrassing you. They make it a positive experience and are willing to work with you on finding what works for your body, fitness levels, injuries, or issues. I can work out alongside someone who's superfit and not feel judged or inferior. They create an atmosphere of we are all there to better ourselves and support each other even when we don't know each other.
