I'm 28, 5'11, 160, and am about to start a fitness regimen. My goals are to add muscle and get lean, as I'd weigh about 140 if not for my gut. I have some questions about weight training, which I have only a little experience with. I've started working out a few times before, but couldn't make it a habit, which brings me to my first question: What can I do to reduce muscle soreness in the days after lifting? Even though I've always warmed up beforehand and stretched for several minutes before & after lifting, soreness is what's always held me up in the past. Should I avoid exercise if I'm still sore from my last workout? I'd like to alternate days of weight and cardio - cycling or erging (I used to row, so I still call it that) - is that a reasonable for a beginner? And can I reasonably expect to work all the major muscle groups in one lifting session? I'm not trying to look like Mr. Universe, just be healthier and look & feel better. My diet is just ok right now, but I've already started improving it - mainly by bringing fruit to work and drinking less beer. I appreciate any answers you guys can give me, as well as any general advice you might have for a weight training newbie.
