Hey- I so hear you!
You are not alone.
I went through a slump myself...and even biking has been hard- well, since Hurrican Isabel- with the wet and stormy weather.
which came AFTER Isabel but I digress >: )

Seriously- I was doing yoga, gym three times a week. Then when the weather was nice- cycling.
But- I can't seem to force myself to go to the gym. Even though I know I will love it when I get there- okay, not love, but feel better for it, and kinda proud that I'm doing it...well, I haven't been for 4 months. And - lets face it, I could be going to the gym when the weather is inclement, but I don't.

Maybe you're like me- more of a team sport person, and it's easier if you have someone to share the experience with?
Maybe you could get somebody to go with you so that you can remember how great it feels? Start slow- but you'll still feel better. It's a start. And if you don't start, you can't finish!!
Try something different- try a community trail just to get you back in the groove. That's what I am doing- driving 100 miles this weekend to go to a bike/hike meeting in a local conservation area. They have tons of different trails for different levels- I'm really excited about it, even though I'm going alone...

Hey- I'm 47- I don't think it's an age thing. It MIGHT be a depression thing though- and the less you do, the more anxiety you feel and the more depressed you are.
Just go around the block...get started...


Good luck- you GO girl!
