When a range of motion (ROM) has been restricted (or “tight”), the potential strength in that part of the ROM is not developed. Strengthening is key! So hand-in-hand with the Active Isolated Stretching (AIS), we utilize the Active Isolated Strengthening (I’ve nicknamed it “+S”). Opening joint ROM becomes more effective when one has the +S to own it. When the basic +S of the joint is established, it becomes a safe option to use this new ROM for other purposes (such as sports specific training).
