To begin this movement, get into a push-up position, with your hands gripping two dumbbells parallel to each other.
While holding the push-up position, row one of the dumbbells up to your side while bracing your abdominals. Stability will be a huge issue with this one, so focus on stabilizing your body.
Once you reach the top position, lower the dumbbell back to the ground and row the opposite side dumbbell up in the same manner.
