Stand with a resistance band around your upper back and under your armpits.
Hold the ends of the band in both hands with your arms by your sides and elbows bent so that your hands point forward.
Pull forwards on the band to build tension.
Keep one arm gently by your side.
Initiate this movement with a step forward as you simultaneously lift your arm up and out to the side, as if about to throw a ball.
Return to the starting position.
