The Standing Side Raise target the shoulders, in particular the lateral and anterior heads of the deltoid.
The standing Side Raise starts with you standing with feet hip width apart, with a dumbbell or kettlebell in each hand relaxed by your sides. Bring both the arms out wide until you form a T shape before slowly lowering back to the starting position.
It is important to squeeze into your core whilst raising the arms and to squeeze your shoulders at the top of the movement.
To increase the challenge of the movement you can lift your pinky fingers slightly higher changing the angle of the kettle or dumbbells.
