Begin the 1 arm clean the same as the 1 arm swing. Swing the bell back through your legs, hinge at your hips, and keep your arm tight to your body. Allow your torso to stay upright, and your eyes to stay on the bell. On the up swing as the bell reaches hip height, slightly bend your elbow, loosen your grip and rotate the bell into catch position. while the kettle bell is coming into catch position bring your elbows to the hip, with contracted gluteus, and soft knees catch the bell, and re-straighten your knees. On the down swing, deflect the upper body slightly back as you drop the bell into your down swing. This allows the arm to stay in contact with the body setting up an efficient back swing.
