Stand upright, arms hanging with the dumbbells in your hands (neutral grip), the backs of your hands pointing to the respective side (away from your body), bend your arms simultaneously/parallel (bring the dumbbell to your shoulder, back of your hands still pointing to the corresponding side). The movement is performed using only the arms without supporting the upper body (leaning backwards). Lower the dumbbells back to the starting position by stretching your arms.
Attention:
Keep your back straight, do not lean backwards (if necessary, perform the exercise with your back against a wall to maintain the position), keep your elbows slightly in front of your body and work without momentum.
Lighten:
Less weight.
Harden:
More weight.
Variant:
Lift your arms alternately to your shoulders.
