The Forward Fly that I outline in Strong Women, Strong Bones is difficult. Most people find that they can only use a couple of pounds when they start the exercise and that they progress very slowly -- this is fine. I encourage you to stick with the Forward Fly for a couple of months even if you can only lift 3 pounds. Certainly rest between repetitions if you need to. Because of the angle of your trunk with this exercise, you are targeting several mid-back muscles as well as your shoulders. I believe that this exercise is very good for improving bone health. I suggest that you mix up your program every couple of months or so -- substitute the Seated Fly for the Forward Fly periodically and vice versa.
