Stand upright, shoulder-width apart in the centre of the elastic band with your arms hanging down at the side of your body (shoulders set). Grasp one end of the elastic band with each hand, stretch your arms sideways up to approximately shoulder height and lower them back to the starting position.
Attention:
Keep your shoulders stable (do not bring them towards your neck), do not hunch your back (tighten your stomach).
Lighten:
Choose an elastic band with less resistance.
Harden:
Choose an elastic band with more resistance.
Variant:
Stepping position, step onto the centre of the elastic band with your front foot, cross the ends of the band and grasp them next to your body (palms facing upwards), arms bent and elbows resting against your body, raise your arms sideways to approximately shoulder height and lower them back to the starting position, keeping your shoulders stable.
