Science of Running
1. Body Position- upright, slight lean from ground. Head and face relaxed. 2. Feet- As soon as knee comes through, put the foot down underneath you. Land mid or forefoot underneath knee, close to center of the body. 3. Arm stroke- controls rhythm, forward and backwards from the shoulder without side to side rotation. 4. Hip extension- extend the hip and then leave it alone. 5. Rhythm- Control rhythm and speed through arm stroke and hip extension.RunBlogger
