Day 4 30 min Express plus a little cardio

It's Day 4 Saturday!  I'm baby sitting tonight, but I wanted to blog for the day too.  I woke up extra early today.  We're officially caught up on sleep now.  We joined Planet Fitness when they opened the location on Portranco because it was very close to us and we could go together on the weekends.  We've both skipped the last couple of weekends.  Today we went to breakfast at IHOP, went to the bank to get some parking money, then went to the gym.  Now Lloyd's normal weekend workout is to park himself on a treadmill for an hour and go, which is great, but it's not what I like to do.  I noticed the express zone was empty, so I went for that again.  This time I upped the weights I put on almost every machine.  I noticed the zone puts a lot of emphasis on upper body work, or at least it seems that way to me.
Ten years ago, when I first joined a gym in Houston, my grandma had just broken a hip.  She was in her eighties.  They told my mom that they were trying to build up her upper body strength.  How much upper body strength can you build in an eighty five year old?  I then looked down at my own arms and decided I should get started early.
I recall some months later looking in a mirror at the gym while doing bicep curls and saying "Wow, are those mine?"  I had definition that I couldn't believe.
I don't think it's so great now, but I definitely am stronger than I was then.  I think upping the weights on the machines was a good choice, but we'll see how it works out.
