Best Shoulder Exercises: Single Arm Cable Lateral Raises
This exercise is a good substitute for dumbbell lateral raises for variety or when dumbbells may not be available to you. Except for the fact that you alternately train each shoulder, the mechanics of this exercise are basically the same as with the dumbbell version. With your arm at your side, simply grasp a low cable handle and slowly raise your arm outward and upward until the handle reaches shoulder height in a position that parallels the floor. Return to the starting position. For maximum effectiveness, you should vary your workouts by starting some sets with your hand at your side, some sets with your hand in front of your thighs, and some sets with your hand behind your hips.
