Hi guys- I just have a question about using weights. Many of you recommend doing full body weights 2-3 times a week, and some of you recommend doing 2 body parts per day. Is there really a difference or is it just personal preference? I like doing 2 body parts per day but if doing full body weights would be more beneficial (aka faster results!) then I will definatley switch. PLease let me know what you think. Thanks! Erin
