Yeah last night I ran a 6 miler. It was pretty cold here in Texas especially when the sun went down. I felt really good though as I got thru the 6 miles in a pretty good pace !
Personally, I have never really minded working out in cold weather. In my younger years, I used to lift big logs with my brother in the winter time. Snow would be falling around us as we made quick lifts in moving the logs just to stay warm.
I know many of you prefer going to the gym to get your exercise. And that is just find. But for me going out and Running with snow flakes falling on my head and face is kind of cool !
Right now I have developed a really good regimen and I have been keeping it for a while now……I do 300 pushups and 300 crunches Monday thru Friday and a 5 to 6 miler Monday and on Thursday !! Thats it ! Its pretty simple and has enabled me to keep my weight around 180 lbs and as my wife says I am mean and lean 
In other wards I am pretty cut in musclarity but not too much !! And my Cardio is running on all four cylinders lately ! Also about 3 times a week I will take my two daughters on a stroll around the neighborhood with wifey joining us many times.
I advise most people that going to a gym can be a really positive thing. For me it has always been a distraction. And you should realize that you can get in good shape and lose weight with simple exercises around your home.
Sometimes you have to be creative and open minded but in the long run it saves you time and money compared to joining a gym !! 
Cheers,
