Working Out for a Better Me

Hey there.  So last night was the first night that I have gone to the gym this year.  I'm not a super hard core gym rat, but I know that once I start going, I'll be somewhat of a regular.  I also started keeping track of my "stats".  I'm a geek at heart and love numbers so I figured that if I added some stats to keep track of, I'll be more inclined to continue to better those numbers.  So here we go, these are my beginning stats:

Height: 5'8''
Weight: 171 lbs
Waist: 37 1/2 inches
Chest: 42 inches
Left Bicept: 13 1/4 inches
Right Bicept: 13 1/2 inches

There you have it.  I don't think I'm a big guy, but I'm not small either.  Waaaaaaaaay bigger than my stick thin 118 lbs that used to plague me before getting married.  I was wondering what would be an ideal weight for me.  Some have said 150 lbs, others say 180 lbs so I'm not sure exactly where I should be.  I just don't want to be huffing and puffing after a short sprint.  And I know I'm out of shape when 22 minutes on a treadmill was damn near the end of me.  lol  Here are those stats:

Over 200 calories burned over 22 minutes of running.  Not too bad, right?  I didn't want to go fast but I didn't want to be all slow either so I'm debating whether or not that average 4.7 mph is a little on high side for someone just getting into the swing of things.  I felt like I was ready to collapse on that treadmill so I toned it down.  Maybe I should be going closer to 4 mph? 

Another stat that I'm a little worried about is the 171 lbs.  Is that too heavy for some one of my stature?  Do I need to go look for some weight loss pills and if so, which ones would be the best weight loss pills for some one like me?  You know, some one that doesn't want to lose a ton a weight but just enough to lose the fat while the muscle builds.  I'll have to take a look into that since I'm not sure I want to take that route, but it's definitely an option. 

So what do you guys think?  Too fat?  I'll be checking on my stats every 2 weeks, maybe once a month and we'll talk about my progress.  I guess I should take notes on what kind of exercise I did too, huh.  I'll see what works best for me.  Later!
