I have a quick follow up question:

If I am only doing weights twice a week, should I be doing a full session of all of the major muscle groups or should I break it up into something like one day of upper body and one day of lower body per week?

Thank you so very much. That will help me immensely! Much appreciated

Hrm, I probably won't be able to train as hard for the marathon as I'd like but I can deal with that. If I run for 30 mins every other day, will I still be able to make significant gains? If I start to eat much more will that help?

Alright, here's the story. I'm 24, and have virtually never lifted in life. I've been a soccer player most of life and have managed to stay in decent shape. Lately, I haven't been as active as I'd like, and I'm starting to get out of shape. In order to get in shape, I've decided to run a 1/2 maratho...
