Hunched forward too much during day? Tight, sore upper back?
This mobility exercise is awesome for upper back and neck tightness and limited overhead range of motion.
Using 2 Acumobility balls placed together in the upper back area, raise the hips up into a bridge position by engaging your glutes and core. With the arms crossed on the chest, flex the chin to your chest. Then raise the arms overhead, drop the head down to the ground and windmill with your arms. Repeat this pattern 6 times on each spot. Find 3-4 spots in the upper back area to work through.
