Dumbbell Prone, Elevated Plank Push-Across

Assume a prone, elevated (arms extended) plank position with feet spread wide for support, and a light dumbbell opposite one hand. Shift your body weight to the side opposite the dumbbell. Push the dumbbell with the non-support hand to the opposite hand. Repeat the pattern back to the starting hand. Try 5-6 dumbbell pushes. Then return to the ground.
