Brian Mackenzie, CrossFit Endurance, leads a dynamic stretch at the CrossFit Endurance seminar Sunday. Try it at home: walk about 10 yards on your hands and feet in this position, legs straight, back extended (notice many rounded backs), heels on or close to the ground, then turn and walk backwards 10 more yards in the same way.
Run 5K. Or come to the gym for a surprise.
