1- Pick one dumbbell and stand upright, legs slightly apart, holding the dumbbell by your side at arm’s length; this will be your starting position.
2- Raise your arm out to the side until the dumbbells reach your shoulder level horizontally.
3- Lower the dumbbell back down slowly to the starting position, and repeat, then do the same with your other arm.
Tips and Advices:
1- Avoid lifting too heavy weights as that is likely to cause injury, instead; aim to do the exercise with reps until you feel the burn in muscles.
2- Avoid lifting the weight above the horizontal if you want to isolate the delts and prevent the trabz from helping out.
3- Supporting your other arm on an object will enhance your balance.
