What People Say

"Joslyn is a quite exceptional fitness trainer - experienced, knowledgeable, totally reliable, always enthusiastic and encouraging, and a lot of fun to work with! When I first started training with her, I hadn't done any form of exercise for the past 20 years and was really unfit. Now, 18 months later, I'm healthier and trimmer than I've ever been - I run regularly, I'm full of energy, and I've dropped 2 dress sizes and can wear whatever I like! And I've not had a single injury, either - Joslyn knows exactly how hard to push. My training sessions with her have made a huge difference to me, and I'd never give them up."
Francis Goodman - Research Scientist

"I have been training three times a week, subject to holiday breaks, with Joslyn Thompson since May, 2005. As a 52-year-old male who worked with another senior London trainer from September, 2003 to May, 2005, I can attest to Joslyn's exceptionally high level of effectiveness and client care. That is particularly important given my own record of injuries from motorcycle and ski accidents.

I intend to continue working with Joslyn for a long time to come."
Mark Raines

"During my time at One Personal Studio, I found B.J.'s training to exceed my expectations. After every session I would leave feeling well above cloud 9. At a difficult stage of my life it was his sessions that helped me battle on and restored a lot of lost confidence."
Dan Wiki

"I wasn't feeling that I was getting much out of attending my local gym and my body was looking out of shape... at One the exercises were interesting and far more efficient than workouts I had done at the gym... As a result of my improved eating habits and training programme, I lost the paunch around my stomach and toned up."
