The banded shoulder pass-through is a great exercise for improving the extension of the arms in the overhead position and improving shoulder mobility!
Hold the resistance band in front of you with your hands spread wide
Place a constant tension on the band
Keep your abdominals tight throughout the movement and your rib cage down
Keep your arms straight and move the band from your front to your back in a half-circular motion
