Yeah, don't take your lessons from reality shows, eits. Those things are about getting eyeballs on advertisements, not about helping people. Similarly, I would probably completely skip weighing yourself for now. I think the pounds are distracting you from your real goal which seems to be, look better and feel better without boring yourself to death. As you know, just weight, or even BMI, is only one small part of the picture. If you want the simple answer, brikis nailed it on the first page. But you didn't seem to be interested, so maybe some of these will help.
You could stand to do some thinking about what exactly you want out of weights. Check out
this link for some quick and useful info on what kind of sets to do for what kind of results. You can exercise however you want to, but remember that your body will respond however it wants to, so it's best to set clear and realistic goals.
I'd hide the scale. Measure all the parts you're interested in growing or shrinking and keep track of them on a bi-weekly basis. Make sure your exercise targets them; better yet, do a professionally balanced routine. Same with your body fat percentage and your jogging performance (total distance, total time, and average speed). Since you lack motivation, see how many goals you can meet and give yourself a grade each week. Show your report card to your gf, your family, us. Take some before pictures, no matter how painful that may be. Set a time (two months?) when you'll show off your after pictures. If you really need to, threaten yourself that you'll post the before pictures here in one month if you don't get your butt in gear and meet at least half of your (realistic) goals. Tell us that, too, so we'll kick your ass if you don't follow through. :frown:
As SC mentioned, you're a smart, educated guy who already knows a lot of this. Sounds like you've got a thinkin' problem. Try meditating on why you're being resistant to good advice. If you want to get good results without complexity, it really doesn't get any better than what brikis said. That's what I say- stop thinking and get to work. This post is mostly for motivation and inspiration, if necessary.
BTW...have you asked your gf what she wants? That could be your motivation right there. Ask for specifics, and be ready to hear them.
Hope I helped!
