Summary: Keeping your arms straight, move weights up and down in front of you. Learn how to do this exercise with free weights in this fitness video from a Pilates instructor.
"In this exercise we're going to keep the arms nice and straight. However, that being said we always need a micro bend in the elbow. The thing that we don't want to do is bend the elbows like this. We're going to start the exercise low, bring the weights out to about here, take a nice inhale, tense the muscles in the arms, and exhale, bring the weights out; inhale in, exhale out; inhale in, exhale out as if you're going through mud; inhale in; so if you're doing it right, you will feel it in your back; and out. We're going to go ahead and raise the weights, without raising the shoulders, and do it again, and exhale out; inhale in, exhale out; inhale in, exhale out. Keeping the wrist nice and aligned with your arms. The last one we're going to do is over head. Again, don't lift up the shoulders, lock them down, and exhale out; inhale in, exhale out. Notice my arms haven't gone like that, but they're still straight, a dash of a bend, exhale out, inhale in. In the last one you're going to feel it in your muscles in the lats along the side of your body."
