Weight Training

Weightlifting (bodybuilding)

Before I start saying anything about weightlifting, if you really want to get a good read I would recommend buying Arnold Schwarzenegger's book:The New Encyclopedia of Modern Bodybuilding : The Bible of Bodybuilding, Fully Updated and Revised by Arnold Schwarzenegger
This book basically sums it all up and it really has so much information. So if you want to be a bodybuilder, fitness model, even a professional athlete, this book is the way to go. I will obviously summarize the most important points of the book for those of you who don't want to read it. I will include personal experiences, new stuff that changed since the book was made (its 14 years old), and all the important stuff.

if you are male or female, weight training is the fastest way to gain muscle. Let me repeat that.

Tipz for Males:

Depending on if you want to gain or lose weight use the recommended daily calorie calculations to figure out where you need to be.
Don't do stupid exercises that you see some guys doing at the gym. (I've seen some pretty stupid trends start at the gym I worked at from one douchebag who didn't know what he was doing)

Tipz for Females:

You will not get "big" or "super muscular" if you start lifting weights unless you are eating three times your recommended daily calories.
Let me repeat that. You will not become a muscular man if you start lifting weights! In fact you will be a sexy, lean, attractive female.
