Book excerpt: Most of us take the acts of sitting, standing, and walking for granted, but for those suffering from back, muscle, and joint pain, even these seemingly simple actions can be extremely uncomfortable. Poor body alignment or habitual movement patterns that crop up when we compensate for a bad back or painful neck can only further exacerbate existing issues—and create new problems. In this accessible workbook, Craig Williamson demonstrates how by just doing these three basic actions with optimal body alignment and attention, you can help free yourself from existing pain and prevent further injury. The protocol is simple but extremely effective, and step-by-step photos guide you through every exercise. Williamson’s approach has been praised by physicians, physical therapists, coaches and sports trainers, yoga instructors, and patients.
