Individual work

Stand upright with your feet shoulder-width apart, arms bent in front of you (elbows at chest height, 90 degree angle at the elbow joint so that your upper arms are pointing forwards and forearms are pointing vertically upwards), stretch an elasticated band between your arms (place the band around your forearms slightly above your elbows). From this position, open the arms/spread them out to the sides (pull the shoulder blades together - retraction/outward rotation of the shoulders) and return to the starting position.
