OK, so i want to burn some fat, and build some muscle, i know that in order to burn fat i need to do lots of cardio and the such, running etc. and for muscle, weights and muscle building exercises. i am also aware that to burn fat you burn more calories than you consume, and for building muscle you need more calories. my question is, it seems that you cant burn fat while you build muscle, or can you? and if not, is it better to burn fat first and then build muscle, or viceversa? thanks for the input.
