Dumbbell Shoulder Press (video above) is one of the best exercise to develop and define shoulder muscles.

* You start this exercise by holding couple of dumbbells with an over hand grip.

* Keep your core tight, chest out and shoulders pulled back.

* Now with your palms facing out, exhale and push the dumbbell over your head by extending your arms fully.

* From here breathe in and lower the dumbbell slowly and come back to the starting position.

Note – Always perform a thorough warm up before starting any shoulder exercise.
