Exercise Routine

It depends on your goals really, but the first thing that came to my mind was "...and what do you know about putting together a routine?".

I say this so much on this site I swear I should buy stock, but buy and read New Rules of Lifting for Women. I swear to god you won't regret it, it's an excellent book about the fundamentals of exercise. It even has a good program at the end for you.

Judging by your question I would venture to say that you do not currently possess the requisite knowledge to sculpt your own routine. There are numerous tried and true routines out there and you should probably do one of those and reap the benefits. Creating your own routine requires a substantial amount of knowledge...it is far more than just "leg day" or "chest day" or whatever...effective programming is very difficult and their are any number of professionals who've already provided you with tried and true templates to use.

For starters, "New Rules of Lifting for Women" and really, any of the "New Rules" library. Starting Strength is an excellent introduction to barbell training and the knowledge learned here will serve you well into advanced stages of lifting. Strong Lifts 5x5 is similar to SS but utilizes a 5x5 format vs SS's 3x5 format...I am partial to the 3x5 format for beginners, particularly if you're at in a calorie deficit to lose weight. The list goes on and on, but I would rank those three tops for beginner lifters.

Utilizing a proper routine is going to garner you the most efficient gains/results possible...trying to invent your own routine is going to leave you spinning you wheels and wasting a lot of valuable time.
