Thanks for the comments!
I am 41 and have been in and out of the gym (mostly out) for the past 10 years. I haven't had much exercise in about 6 weeks. Prior to that I was on the treadmill 3-4 times/week and felt like I was in pretty good shape.
I have visited with my doctor in the past about these concerns and the tests come back normal.
I quit drinking alcohol about a month ago and am trying to get back in shape.
I guess this is something that needs to start slow and work up from there.
It was alot easier to workout when I was younger.....
