Standing, grab a Loop Band with both your hands about 10 cm away, then slightly open them until they are in front of your thighs (starting position).
Holding your torso upright and your arms straight, open your arms outwards, pulling the band. A few degrees of opening (abduction) are enough.
10/12 x 3 sets
Bending your arms, exceeding on the range of motion, grabbing the band with the hands too far away.
