I'm 5'10" and 162lbs. I go 3 times a week to the local gym and do (this is mostly on machines, except lower abdomen I hoister myself up and kick my legs out):
Pulldowns/upper back - 3 sets, 10 reps @ 130lbs
Shoulders - 3 sets, 12 reps @ 75lbs
Biceps - 3 sets, 10 reps @ 45lbs
Triceps - 3 sets, 10 reps @ 60lbs
Chest - 3 sets, 10 reps @ 105lbs
Leg press - 3 sets, 10 reps @ 200lbs
Abs - 3 sets, 30 reps @ 50lbs
Lower back - 3 sets, 10 reps @ 100lbs
Lower abs - 3 sets, 12 reps
No cardio, since I'm a bit too lazy and I have aortic stenosis (a heart condition). Though I do mountainbiking from time to time for fun. I just started earlier in the year, looking to gain a bit of muscle and tone, and trim down my gut a bit. I was always thin person, with a good metabolism + decent diet (although I'll go a bit heavy on the meat and carbs from time to time). But, after going, I feel great and working out has done wonders for my confidence. Not to mention, I've been getting some more looks from women ever since I started going, which in turn inspires me to go more.
Am I on the right track, or are there any other suggestions you guys have?
