becoming one of those people

I haven't been doing too well with my usual attempt to go to the gym three times a week - busy times at work followed by Christmas holidays, followed by more busy times at work and travel with work (not to mention this whole "I run a church in my spare time" thing) have got me down to about once a week for the last month. Yesterday, I actually went at 4pm on a Saturday to at least get that much in - and it felt great. I thought that the cardio would kill me, since I've been so sporadic, but I was feeling wonderful while I did it, and after a walk home with my earphones still plugged into my workout playlist, I felt so healthy and invigorated that I ate a grapefruit. I don't know how it happened, because I never was before, but I have become one of those people who just feels so good when they exercise. Eek - if I'm not careful, I'll be taking up running next . . . .
