Adam, I don't do much weight lifting.
Casanova, I don't want to gain weight (I was 300 pounds 5 years ago)....I want to stay where I'm at (170) and if I do gain, I want it to be muscular weight, not fat. I'm currently doing anywhere from 20-30 minutes a day (not on a track, but a treadmill set at the highest incline, I know it's no substitute for a real hill, but....) because I'm just now starting to get serious about this and I can do a mile in 13 minutes running at about 4.3-4.4mph, which I know I can improve.
As far as diet, I can say that it's a lot better than it used to be

.
Very rarely do I eat out, and very rarely do I eat
red meat anymore (am eating lots of veggie meat products)......My diet is low in cholesterol, and on a daily basis I rarely exceed the
daily intake levels of fat, sodium, cholesterol, etc. etc.
Hmmm....let's see, what else can I tell you.....I guess what I want is a routine that will help me stay cardiovascularly healthy, and not necessarily focus so much on muscular training. I hold a corporate job where I am inactive for most of the day, and I want to do something to make up for that.
Anything else you need to know?
Thanks for the quick advice.
