I'm brand spanking new to weight lifting (I really know nothing) and am trying to start off with the basics in order to lose some weight. I've got my "Men's Health" program for beginners/intermediates/advanced ... but the silly rag doesn't specify how heavy the pair of weights should be for each level. I'm not weak but I've also never lifted a weight in my life. My goal primarily is to lose weight rather than bulk up. So, what should I buy guys? Thanks.
