Start with your arms above your head in a “Y” and gently squeeze your shoulder blades together and hold 10-20 seconds. Next bend your arms down to a “W” and keep squeezing your shoulders together for another 10-20 seconds. The “T” is next and keep squeezing, finally the “L” or Double “L” is the last part so that you can get your big lower back muscles involved for another 10-20 seconds. Each of these different positions works different back muscles and stimulates your back and your posterior chain to hold you upright. I like this exercise first followed by the spinal twist to work as a ‘team’ exercise to stimulate your brain and upright posture.⁠
