A full and complete shoulder workout routine using only kettlebells could be made up of only 5 exercises.

In a kettlebell swing, you begin with your feet shoulder-width apart and the kettlebell placed on the floor in front of you and between your feet. Bending your knees, you grab and pull back the kettlebell in between your legs to create momentum. Then, you use your hips with the momentum and straighten your back, bringing the kettlebell to shoulder height. After, you bring the kettlebell back down and repeat.

You begin by standing straight with a kettlebell on each hand and your arms on your sides and slightly apart from your body. Your feet should be shoulder-width apart. Without bending your elbows, bring the kettlebells up to your side at shoulder height. Then, slowly lower your arms in a controlled manner back to the starting point and repeat.

Start with your feet hip-width apart and bent over at the waist, bending your knees only slightly in order for your torso to be nearly parallel to the ground. Hold a kettlebell on each hand with your elbows slightly bent. Then, raise the kettlebells to your sides to shoulder height.

You begin by standing straight and putting your feet together. Holding a kettlebell on each hand, put your forearms in a vertical position and keep your wrists straight, with your knuckles always facing the ceiling. Then, push upwards until your arms are straight above your head. Slowly lower the kettlebells back to the initial position and repeat.

Start by standing straight with a kettlebell on each hand, your arms on your sides and slightly apart from your body and your feet hip-width apart. Then, shrug as high as you can while keeping your arms straight, and pause at the top for a few moments. After, slowly lower your shoulders and repeat.
