Great thread, PhilL. I remember replying to your fitness thread one year ago, as well.
One year ago, I'd recently had a complete reconstruction to one of my lower legs, as it had been crushed by a boulder 5 years hence and had serious difficulty recovering. After about 2 months, I was out of the cast and back on my legs. My doctor's advice was to walk, walk, walk and bike, bike, bike. In addition, I lifted weights with my upper body. Along the way, I found some great techniques for building muscle and burning fat simultaneously (getting an aerobic and anaerobic effect) using weight lifting.
These days, I'm back in school and close to finishing my bachelor's. WIth the spring term over, I can spend more time exercising; I've only got one class during the summer session, a basic physics course to finish my general eds. I'm 30 years old, 5'11" tall (although I lost 1/2" from the crushed leg) and weigh 194 pounds. My summertime goal is to hit a consistent 190 lbs. I've also got some strength and endurance goals, as well.I lift weights 3-4 times/week, walk my dog 3 times/week, and do a cardio-specific workout 2 times/week.
In May 2002, when my leg was crushed, I weighed 185 pounds. I dropped 20 pound over the next month. 6 months afterwards, though, I was eating like a horse (which the doctor advised

) and, due to increased intake and physical inability, I'd gained 60 pounds, weighing in at 225. As my leg healed, I was slowly able to be more active and dropped down to about 210 pounds. By last March, when I had the complete reconstruction, I was weighing 195 pounds, but was incapable of walking more than a mile, due to extreme pain.
Nowadays, as my leg continues to improve, I'm feeling better and better. In order to regain my walking ability last summer, I did just what PhilL said he does - I started walking a little bit and added a slightly larger distance each day. One year ago, I couldn't walk to the end of my street and back without extreme pain and multiple rest stops. Nowadays, I can do at least 4 miles and am pushing for more. The take-home lesson? Start moving your body, or weighted objects, through space each day, a little at a time. As time goes, with commitment, health, strength, endurance, and well-being will significantly improve!
Oh yeah, don't ever think that it's not possible to get a good cardio workout from lifting weights. A great technique is Charles Staley's "Escalating Density Training". If you're pressed for time and need a one-stop exercise method, this one works very well.
