“I look forward to training with Karen every week. She highlights the gains made in personal fitness, and coaxes you on to achieve a little more every time. Karen is obviously super fit, and an excellent motivator to people of every fitness level. She uses her knowledge and experience to create diverse sessions, while explaining well which exercises target which areas of the body. I feel much fitter, and am enjoying the structure Karen’s classes offer. I would highly recommend the joys of HIIT with Karen!
