This upper back and shoulder active flexibility plan is PACKED with a TON of great information on safely improving backbends- starting with shoulders and upper back! This plan has photos, descriptions, AND links to full videos of each exercise. More importantly, it explains the "WHY" behind my active flexibility exercises...what makes these exercises work, and why we focus on specific muscle groups. This program is meant to be used as a SUPPLEMENT to your current stretching/contortion training. Please note: there is NO discussion on passive stretching, this focuses only on active flexibility!
