We all want those arms that don't flap in the wind when we're waving hello, right? These five exercises with light weights make it look easy, but the small isometric moves ensure you feel the burn. Grab your two- or three-pound dumbbells and get going, but don't worry if you don't have weights — you can even do them without for some excellent toning.
A lot of times we do a full rotation for our biceps. Instead of taking the exercise all the way, this exercise stops when your arms make a right angle.
Instead of wheeling your arms around without much effort, move your arms in a square motion, making stops at each corner. Your deltoids will feel the burn.
