The Triangle Push-Up exercise works your shoulders, chest, triceps and core.
Armed and fabulous. Your hand should be under your chest so that your index fingers and your thumbs form a triangle. You'll bend your elbows out about 45 degrees to the sides. Lower your chest to the floor, push up, and repeat. To make this easier, place your palms on a counter bench or sturdy chair. Do 10 to 15 times.
