So Penn's gym has this special membership for alumni. I could join for about $20/month through the end of August. And it's not that far for me; only about a 20 minute walk.
The catch? With this membership, I'm only permitted in the gym from 6am-8am, Monday-Friday.
Is it worth it? Will I actually wake up in time to go? Should I just buy DDR and get my exercise that way?
