I have to agree that everyone here has some good advice. But in the end it all comes down to what works for you.
If you took any 5 of us in this thread and put us all on the same diet and the same exercise program, you would get 5 totally different results. THis is actually fairly true even if you took 5 people with the same height/weight dimensions.
While everyone's body reacts similiarly to exercise, it's not identical.
As far as the slow reps thing, I'm not a real believer, but if it works for you, then it works.
I'd take one of the few guys on this board up on their offer to write you up a program. They seem to have more experience than myself with formal programs - I know what works for me, I can only suggest it to you… heheh
Try the program for a month and check the results - talk to your new "trainer" about the results you are and are not seeing so far, and they can modify the program to add a little more focus to the areas you need. A month will not transform your body, but you should be able to tell the direction it is heading if you are strict with your workouts.
One last item - know your body ( I hate saying that, I feel like a highschool councillor about to talk to a bunch of teenage girls….heheh)
Know it - know the difference between strain and fatigue. Fatigue is fine, strain is real bad and just knocked back your workout a few weeks.
Know it - Form! Gyms have mirrors so you don't hurt yourself, not so you can check to make sure you look pretty. You may feel that you're standing straight but look like a friggin pretzel in the mirror. Proper body position sitting/standing/lying down etc will focus the workout on the desired muscles, and save you from possible injury/strain etc.
