I have been doing pilates for a few months now, and I am thrilled with the results. Now I would like to add some sort of weights to my routine, but i'm not quite sure where to start. i would like to continue to tone up all over, but Think Ineed to build especially in my shoulders and back. I am not quite the pear shape, but with itty bitty shoulders and a larger chest ,I look out of proportion.what exercises should I do to build my shouldersand maybe my back to balance it all out? Any help would be appreciated.
