Rowan Ellis, founder of the Body Synergy gym, has a simple but compelling approach to relieving musculoskeletal pain. His hypothesis: to protect the spine and joints, one must contract the right muscles at the right time. Rowan believes that poor physical awareness of which muscles we are using, especially the trapezius, is a root cause for a variety of back problems and some forms of migraine. The Delsys EMG system allows him to view clients’ muscle activity in great detail.
