I can completely relate though I haven't been in that age group for some
time now.  Prior to my weight loss, I used to go out every friday after work
for beers and appetizers.  Eventually it got to where I had to shift things
around to fit everything I needed to do into my schedule as exercise became
a priority. Due to classes and meetings and leagues, Friday after work
became the one weekday I could have a decent workout and then dinner with DH
because it is the one time I will definitely get out of work on time - and
the gym is empty so there is no wait for any equipment.

The best thing to do is make a plan and know that life will interfere with
your plan :)  Good luck!
