I always try to go during off peak times, so I'll do a lifting session around 2:00 in the afternoon. My 12 year old is now wanting to work out, so I snuck him a membership to my Fitness Connection (he's tall for his age, and the broad signing people up hooked a nikka up on the low low). So I'll take him and finish my lifting and do cardio around 9:30. That gives me an hour and a half before it closes. I do that on weekends, too. Closes at 7:00, so I'll get there around 5:30 if we ain't doing anything.
I wish I lived near Lifetime Fitness. When I was going there, a nikka would be in the gym on a weekend at like 2 in the morning, had the whole place to myself...
