Practice these for a few minutes each day and within a few days you will find that you won't have to think about how and where to place your feet when you practice Injury Dynamics. These exercises are presented as taught by Chris Ranck-Buhr, founder of Injury Dynamics in San Diego. After each movement, check your posture and structure (back foot flat and back leg straight). In the Cross-over step, your forward foot is turned 90 degrees for balance. In the knee drop stance, your forward foot will be turned in slightly inward for balance. If you want to turn this into a leg work out, you can do each posture for 30 seconds or 1 minute. Chris often states that the Leg Dynamics are the single best way to improve your Injury Dynamics.
