Being that you want to gain some size i would quit running. If oyu want to work on “getting in shape” I would do some HIIT…for example sprint 100 yds then walk for a little bit then sprint another 100 yds…and so on. That will get you back in shape and reduce the 3 of calories you burn. But for size bench, squats, DL’s, cleans, and shoulder presses are a must…all while eating a ton.
