Tell us about your new research Our work, published in the Journal of Science and Medicine in Sport showed certain types of exercise trigger greater fat-burning than calorie counting suggests. For the study, 12 healthy females cycled on a stationary bike and did a Les Mills Bodypump class. On all counts, the results showed a greater response to Bodypump than to the calorie-matched, steady-state cardio workout. When blood lactate levels were examined, they were 81 per cent higher after Bodypump than cycling. Human growth hormone was 56 per cent higher. 16

Have any other research findings surprised you? Last year, we set out to explore the effects of our immersive cycling programme – called The Trip – on the rate of perceived exertion. We discovered that combining immersive audio-visual effects with a structured workout gets novice exercises
