I go to gym almost all days. For every workout I use to weight train one muscular zone and run about 50 minutes (at low rates, about 130/140 bpm). My target is to burn as most fat as I can (I'm male, so my fat is particularly on belly). Sometimes if I haven't time, I prefear running session (always at low rates, and always about 50 minutes) to the weight train. I'm 28 and my body is athletic, and I always do some sports in my life. The question is:
What should I eat before the workout? What should I eat if i'm going to just run? What should I eat if i'm going to make both weight train and running session? How much time before the workout? Is weight train on empty stomach unuseful or at worse bad for muscles?
