Step 1: Stand straight with your feet placed shoulder-width apart or sit upright on a flat bench with back support. Secure the dumbbells in both the hands and position them in front of the chest such that the palms are facing towards from the body.
Step 2: Gradually raise the dumbbells overhead while twisting your arms outwards. Ensure that the arms are fully extended, and the palms are facing away from the body in the final position.
Step 3: Pause for a second and return to the starting position.
Repeat the exercise for the recommended number of times.
Important tip: Keep the elbows close to the body throughout the duration of the exercise.
