Start with a lightweight kettlebell in your right arm. I'm using a four kilogram kettlebell which is roughly 9 pounds.
Lift your arm up turning the kettlebell upside down, 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.
