I have been exercising since before i started cd,i dont think its made a huge difference to my losses(i`ll never really know for sure)but i am really toning up nicely,i can really notice my arms,my legs on the lower part of the thigh,not so much the top half,well getting there i suppose.
i just do it to tone up as i go so im trying to avoid saggy skin in any area,hope this helps you a little,
