Start with a lightweight kettlebell in your right arm. I'm using a four-kilogram kettlebell, which is roughly nine pounds.
Lift your arm up, turning the kettlebell upside down and creating a 90-degree angle at your elbow. Be sure to keep your wrist straight. If you notice that your wrist is moving, use a lighter kettlebell or a lightweight dumbbell.
From here, begin walking forward. Take 20 steps forward or walk for 20 feet, depending on the space available.
Switch the kettlebell to your left hand and walk back to your starting point.
