Yay or nay: Working out on a Friday night?

I read this post over on Fitsugar about working out on a Friday night and how it can get you going for a great weekend and it got me to thinking, is there any truth in that? I think, like most things in the health and fitness arena, it depends on personal preferences. Exercise is relaxing, and if you have the energy working out at the end of a long week could really start your weekend off right. Plus I would think that even if you have plans to go out and have fun squeezing a workout in beforehand would certainly help boost your confidence and buffer some of the guilt from the beer and chicken wings.

But then maybe that time after you get home from that long stressful week is about no plans, no demands, just relaxing and kicking your feet up.

What do you think? Friday night workout session a good idea or not?
