Stand upright and grab a pair of dumbbells with your arms extended at your sides (Palms facing in).
2. Flex your shoulders to raise your arms to shoulder height, hold the contraction for a moment and slowly lower your arms but do not return to the starting position.
3. Once the dumbbells have reached hip height, raise them back up and after a brief pause, return to the starting position (This counts as 1 rep).
4. Perform the movement for the required number of reps.
