Hold a light dumbbell in one or both hands and stand with both feet together. (Holding two dumbbells makes the move more challenging and may help you keep your balance.)
Step one foot back into a staggered stance. Keep 80 percent of your bodyweight in the front leg with a slightly bent knee. Square your hips and chest over the front foot. The dumbbells should be hanging by your sides, straight down over your front foot.
Using the arm on the same side as your rear leg, lead with your elbow to drag the dumbbell across your chest into a high row, as if you were drawing an arrow from a bow.
Allow the arm to straighten completely out, creating one long diagonal line from the top dumbbell to the bottom arm and dumbbell.
Keeping the top arm straight, slowly lower the dumbbell back down to the starting position. Keep your core tight and focus on a slow and steady range of motion.
To increase the intensity, perform the same move while "floating" the rear leg straight above the ground behind you, not letting it touch the ground.
