Pick up the kettlebell with good technique, as though you are performing a single hand deadlift. Do no round your spine as you bend down to pick up the kettlebell.
Stand tall and walk with upright posture. Imagine you are balancing a book on top of your head as you walk.
Seat your shoulder back in the socket.
Keep your elbow straight. Engage your triceps, the muscles on the back of your arm.
When you are ready to set the kettlebell down, do so with good technique. Do not round your spine. Instead, hinge at your hips and use your legs as though you are performing a deadlift.
