 Rowing is where it all began for Katherine as a member of Lea Rowing Club where she currently runs and teaches their Row to Fitness programme. She moved away from training with crews on the water and into Strength and Conditioning and now uses land based rowing as way of re-enforcing core strength gained from moving and lifting all things heavy, and for getting on a great sweat.


A professional actor trained in New York, when Ryan’s not on stage he’s teaching TRX, Row30 and Frame Fitness at Gymbox. Having returned to the UK a few years ago, Ryan loves his job at Gymbox and admits that London definitely has his heart now.
