Stand upright and raise your arms straight forwards (frontal), palms facing up, until they are at shoulder height. Maintain a static position while keeping your upper body upright and shoulders relaxed. Look straight ahead and keep your legs stable at hip to shoulder width.
Attention:
Do not raise your shoulders, but keep them relaxed and down; keep your back upright, do not hunch your back; keep your arms straight, but do not overstretch your elbows.
Lighten:
Only hold your arms for a short time; choose a lower height (e.g. only raise them to chest height).
Harden:
Use additional weight (e.g. small dumbbells, water bottles, medicine ball); hold the position for longer.
Variant:
Extend arms laterally; palms facing up.
