starting to commute by bicycle again

My wife and i have had only one vehicle all week and my wife's been taking it to work. I've been riding my old, beat up, 90's model Raleigh mountain bike everyday to The Miller Gym and work. At first i was afraid the cycling would hurt my weightlifting. But i think the cycling is actually helping it. I used to struggle getting my legs warmed up and ready to lift heavy. This week, by the time i bike the 11 miles to the gym, my legs feel great and are ready to lift right away. So it looks like I'm picking up commuting to work and gym on my bicycle again.
