If you are hoping to lose with just lifting.. you're in for a wait.. you can't lose weight without burning the calories, and going to the gym does not 'burn' as many as cardio.. you will naturally burn more with the increased muscle, but chances are you won't notice anything for a while.. pants will fit better as things are tightened up.. but it's not really a change in composition for fat.
That's just my thoughts though... I know for me I can focus on one of the two at a time.. either drop weight, or gain size.. I can't seem to do both at the same time. I'm not a competitor so I don't have coaches and what not or someone to make meals for me.. it all goes to what you're putting in though. Regardless of what you do in the gym.. it starts in the kitchen.
Right now.. I'm in a horrible place for training. working 60+ hours a week.. and when I say plus... it's usually around 74 a week. I have zero energy or motivation for the gym, just trying to keep life rolling along and see the fur kids and maintain a house.. I'm not happy. Not happy to the point of just going and getting a job in retail at 40 hours a week and saying fuck having $$$.
