Health: Multitasking, Shoulder and Calf, Plank to Pike

You can save time when you exercise by doing strength training exercises that work out more than one part of your body at a time. So, here's one to add to your routine; it may look easy, but it will have your shoulders and calves burning in no time:

1. Come into plank position with straight arms and legs, holding a dumbbell in each hand on the floor. If you don't have any dumbbells you can place the palms of your hands on the floor or on two yoga blocks.
2. Keeping your abs engaged, slowly tiptoe your feet as close to your hands as possible, with straight legs. Keep your heels lifted the entire time. Then, moving with control, tiptoe your feet back to plank position. Don't rush your movements.
3. This counts as one rep. Complete three sets of ten reps.
