honestly at 140lbs I wouldn't bother with any sort of fancy workout routine. just a squat/bench/deadlift day and have at it.
I started out @ 130lbs and I spent so many hours squandered away on strange & useless accesory lifts (wrist curls, lol!) and it wasn't until I read the tips in this forum that I started to change my whole routine.
I stuck with deadlifts, squats, bench presses, standing military presses & rows. Very simple stuff, nothing fancy, but I made sure to add about 5 lbs regularly. At first, this is pretty easy and soon you reach a level where even 5lbs seems like you just added 50, but adding weight is necessary! Unless you do that, your body will simply adapt and quit growing. You much "shock" it.
I've reached 160lbs now. Granted, I started at an abnormally low weight due to an accident, and some of my new weight is admittedly blubber, but there is a lot of muscle in there also. I'm 5-5, so 130 didn't look too weird, but 140 on your frame sounds skeletal
