If you're relatively inexperienced at strength training I highly recommend buying "Starting Strength" by Mark Rippetoe
http://www.amazon.com/Starting-Stren...rting+strength
It will give you very in-depth instructions on doing the basic strength exercises (squat, deadlift, bench press, military press, power clean) and also has several options for linear progression programming. It's a great way to quickly build strength and familiarity with the exercises. A lot of people when they first try to get into shape do too much right off the bat. You're better off sticking to a simple plan with exercises that incorporate multiple muscle groups.
As you start to plateau on the linear progression that would be when you want to start incorporating the supplementary exercises to address weaknesses. Anyway, just my 2 cents.
