In the upright position, grab a Loop Band keeping your hands about 20 cm away from each other, then raise your hands and open them in order to keep them perpendicular to your torso (starting position).
At this point the band will be slightly under tension.
From the starting position, wide your arms to bring the Loop Band against your chest.
8/10 x 3 sets
Choosing a band too large: a microband 6mm is enough.
Leaning your head forward while performing.
