at 5'7" and 135-140 you will be one scrawny ass mofo....I'm 5'7" and I cut to 159lbs for wrestling and I'm pretty cut at that weight....I just decided to start bulking up again last week and I am at 175lbs of muscle. I'm not sure what type of body your going for in the 135-140lbs range but if it's not a chicks body I would start eating a healthy diet with about 2500 - 3000 calories, about 150 - 200 grams of protein and hit the gym 5 days a week....if you don't want to do cardio don't sweat it...the added muscle mass will boost your metabolism enough to take some fat off you....plus running at night isn't good for your sleep cycle...unless you plan on sleeping during the day
