Bran,
I'll argue til I am blue in the face that squats, when done right, are one of the safest things you can do in a gym, lol.....but besides the point, I feel your goals are very attainable. You have a good, solid build and good body composition.
First of all, the word "routine" needs to be addressed.....there really is no routine in the way most people think of it (a magic forumla to get hyooooge and jakked, lol)....all a routine is, is a way to organize your training so that you can make improvements.....I can think of 20 different 'routines' that would suit you fine off the top of my head....also, any excellent routine somebody gives you can be tweaked a million different ways and still be just as excellent. So, I will give you a sample of something that should work for you unless you fuck it up (ie, refuse to eat, try to live on boiled chicken, sub in lat pulldowns with 37 different attachments in place of rows, or anything else that should be considered a criminal act, lol).........The important thing for you to see is NOT days/sets/reps/exercises, but PROGRESSION, whatever you do should be progress-oriented, if something won't help you get better at a few compound lifts, then it is fluff and a waste of gym time.
So,a 'routine' that will foster progression of lifts that you may enjoy is something like this.....(I will leave out cleans as you're unsure about them, and doing them wrong only makes it harder to un-learn the bad habbits when you get someone to show you)
Monday:
Flat Bench: 5x5, pyramid up to 1 top set of 5; then 1x8 as backoff
Dips: Bodyweightx 4 sets , once you get all 4 sets x20, add some weight
Tuesday:
Barbell Row: 5x5, pyramid up to 1 top set of 5
Squats: warm-up, get ready, and do 1 set of 20 rep breathing squats, not a gay high rep set, but a true set a breathing squats.....look at Blut Wump's journal for a vid of how they're done.
Decline Situps: 2 sets to failure, once you get 20 reps, start holding plates behind your head, once you get 20, add more weight.
Wednesday :Take off
Thursday:
Flat Bench: 5x5 (warm-up, then use the same weight for all 5 sets.....you'll have to use less weight than you did for Mon's top set obviously.....a good starting point is 75% of Mon's top end set, then add 5lbs a week from there)
Push Press: 5x5, pyramid weight each set, follow-up with 2 sets of 8 strict presses (standing of course)
Friday: Deadlift (5x5, pyramid weight each set)
Jump Shrug (3x12, add weight each set)
Biceps (1 exercise for 3 sets of 8 or so, just try not to pick something too homosexual, ie; anything on a cybex or universal machine)
Some general rules.....start conservative, or you'll hit a wall and progress will stop....DON'T miss reps, having your spotter touch the bar means the lift doesn't count, spotters are for safety only, you gain through progression, not by getting sore and pumped. Add 5lbs a week to the rows, bench, push press, 10lbs to the squats, and shoot for 10 on the DL.
Thats something that would work in a nut shell, there are a trillion other things that would work just as well, so just read the underlying principle (get good at big lifts and use sets/reps to tell if you're getting good) then apply it to whatever routine you choose.
