Hi, I'm Ken...
...and I'm an "athletic alcoholic."
I still have to use that at a meeting some day!
Yes, I tried training for years while keeping up my daily beer habit -- guess what -- it didn't work!
So, now I am slowly getting back into training, losing weight and preparing to race (triathlon) next year.
When I say slowly, I will not even attempt a running program until I get some weight off, and get to 15% body fat, to avoid injury. I also ride my bike, and will get back in the pool pretty soon...
Don't know how old you are, but I'm 41 -- but you can be an athlete at any age I believe... again, just take it slow...
Ken
