Your Body, Your Yoga is the first book in a series describing the many contributors to limitations in our yoga practice. This book looks at the lower body, and the variety of shapes, movements and potential restrictions to movement in the hips, knees, ankles and feet. Introduced are the causes of resistance to movement, the frequency, extent and consequences of human variation, and their implications for our yoga practice. While short, tight muscles can restrict movement, there are many reasons for a lack of mobility. The causes can be cast into a gradient, called the “What Stops Me? Spectrum”: fascia, ligaments and joint capsules can be tight and tense, while compression arising from the body contacting other parts of the body will also impede movement. How these tissues develop their tension may be due to actions of our nervous or immune systems, or it may be due to our inherently unique body structure. Compression is the ultimate limiter of movement and is variable, depending upon a student’s individual skeletal structure. All students are unique to varying degrees, and this individuality determines their ability and progress in their yoga practice and its benefit for them.
