We caught Reese Witherspoon leaving her spinning class in Brentwood today, and yet again, she's got that post-workout glow! Well, as much of a glow as you can get in 50 degree rainy weather...

Reese has always been in great shape, but it seems like after her split from Jake Gyllenhaal, she's been taking the personal fitness thing to a whole different level. Is she doing it to get a hot revenge bod, or do you think it's like therapy for her? Both maybe?
