Ten years of desk work & limited exercise

I wrote this post about a month ago, I thought I lost the writing when by laptop crashed, but I just figured out these posts are automatically saved as a draft.... so here it is a month later. I am going to leave it as is and just post an update later.

I have only been in a health club or Gym, 4 times in my life. The longest single stay was last year as part of my therapy for a torn rotor cuff in my shoulder. I attended for about 10 months, but at 3 days per week. I have been slowly gaining weight over the past 10 years, and I have been thinking I need to join the Y or a health club.
I priced the Y and it was a little pricey, and a couple of popular clubs, also pricey.
I was at second hand book store a couple weeks ago and came across an exercise book. I bought it and to my surprise when I used a table in it to calculate my body fat, I fell into the obese category. I was surprised because I weighed 255 and am 6' 4" tall. I wear 34 X 34 jeans. My problem is I am starting to look like I am pregnant. (About 2 months). Well that was the last straw. I joined the local Health Food Coop, and have upgraded my eating habits. I found a health club less than a block from my office with good rates. The January special was $95 to join and $25/month dues. They do not have a pool or sauna, but there is an abundance of new machines, and a full weight room. The facility is fairly new and is kept clean. I joined last week Monday and have been going once a day M-F for about 45 min. exercise.
I started out light, basically 30 min. on the treadmill. I have been walking at a 20 minutes mile for a total of 1.5 miles per day. When I first weighed in I was 255#. Today I weighed in at 249#.
Last Saturday I bought a Micro life blood pressure tester.
My pulse seems to vary from 65-114. The 114 is during a workout. My first blood pressure test was taken on 1/14/08 @ 7:30PM
Systolic---167
Diastolic--105
Pulse-------65
On 1/16/08
Systolic---143
Diastolic--93
Pulse-------89
