Plank Row
Planks are awesome for your core and rows give you that sexy back for backless dresses so why not try the two together? Start in a plank position with your hands on two kettlebells (dumbbells work great too). Keeping your elbow close to your body, lift one kettlebell up. Repeat on the other side. Dude tip: Try not to rotate your hips out when you lift the 'bell.
