Speaking as a complete beginner myself--but in the gym 3 or 4 times a week, working on the diet and reading everything to with training and nutrition..oh and being a total old fart as well....and just 7 months in it's totally absorbing and fascinating doing it and learning about it.
Its hard to know where to start with an answer that isn't immediately disrespectful.
It's true that there is tons of information on here and loads of it would be relevant, equally loads of it would be way over your head. With so much information it could be hard just to know where to get started.
We live in an information (overload) age but as i always said in my bushcraft instructor days 'information isn't knowledge' amd knowledge is the thing that starts to happen the moment you start to do the thing you are trying to do..
You almost need a basic guide to the basics.
A few threads above this one is one along the lines of 'new to t nation' that is a good start because first off it will teach you how to post a better question, as is you haven't really given any useful information and are just going to get quick and rough answers.
The basics (from another beginner) are :
You have to start learning the basics of lifting weights ie :
Picking weight up
Putting it overhead
Moving weight around.
And that probablly means finding a gym and a good solid trainer to teach you the absolute begiinings of :
Some form of squat movement
Some form of deadlift
Some form of press ie bench and overhead.
How to warm up
How to stretch
Learn to move your weight around ie:
Press up,pull up, walk, run ,cycle or row.
Get stuck in and do the above 3-4 times a week.
Work out what you are eating--keep a log of it and post it right here
Learn the basics of nutrition and apply that knowledge.
Repeat for a few months until you have the basics squared away.
Giving us more to work with would help too..so tell us what you are doing now..what you have done and any ideas you have.
