Holding medium to heavy dumbbells, begin in plank position with hands directly under shoulders, keeping wrist neutral. Keep legs extended and open to provide a wider base of support. Keeping spine neutral, pull (row) dumbbell to hip without tilting hips (A). Lower dumbbell to floor, and repeat on other side. Then do 8 mountain climbers, bringing knees to chest (B). Repeat the cycle of 2 rows and 8 mountain climbers for the entire minute.
