I don't want to look like a muscle head, my goal is more definition. I want to continue to loose my waist (obviously) but I would like to clean up my lines, especially in my torso. How should I go about that? keep in mind that I am still in fairly horrible condition and I am having to start from scratch since I was never an active person to begin with, I had a 6-way bypass about 18 months ago, and I still smoke (yea yea I know). The surgery doesnt really effect me anymore except occasionally if I do something wrong I feel my sternum slip around (boy that is a weird feeling) inside my chest. My strength is better than it was before the surgery tho and I dont have any fears of tearing anything unless I do something really stupid and I have been fairly good at avoiding that...so far.
Currently I dont vary my workout at all I hit the gym three times a week but I am hoping to get that up to 4-5 week at some point. It consists of 45+ minutes on the treadmill at a 1.5 elevation 3.5mph. I tried jogging but I got REALLY winded and had to stop. I decided that with the known heart problems it didn't seem to be a good idea at this time (At least thats how I rationalize not jogging :p) I realize that if I quit smoking I probably could do this, but I have been consistantly unsuccessful at quitting, soo..... At any rate, when I am done with 45 minutes of walking at that pace/elevation I usually feel the "burn" in my legs, so I guess I must be doing ok. When that is done I hit the weights. I wish I could tell you specifically what I do, but I dont know enough about this stuff to even describe it very well. The excersizes I do I learned from watching others, I realize that I could do more damage than help if I am not careful, but I guess that is why I am here

Should I be trying for heavy weights and few reps/sets or less weight high reps/sets? Any specific excersizes that I could try? I looked at that "Killer workout" thing but jsut guessing I am thinking I might require the services of an ambulance or a coroner if I tried that at this point. So where should I start?
The gym I work out at has a bene with my commitment where I get 2 free sessions with a trainer, which I haven't used yet, but I am too broke/cheap to pay for one after those are used. So I was kinda hanging on to them until I felt like I was in good enough shape to benefit from those sessions. So now that I have been completely vague and providing no information while asking you for a complete plan, got any ideas?
