Legs like Jello

I planned to run outside yesterday after work, but it looked like rain, so I went to the gym instead.  I got to the gym and I got talked into a "free" personal trainer session.  It was definitely a good work out and my legs were like jello afterwards.  I didn't really appreciate the sales pitch afterwards, but like they say, "There is no such thing as a free lunch".  I was really considering it, but at $180 a month for one session a week.  That's too rich for my blood.  After the sales pitch, I decided I still wanted to run, and boy, was it tough.  Definitely jello legs.  I made it through my normal three miles and then did some physical therapy exercises since my knee pains are coming back after my longer runs and after long hours of reffing.  I woke up this morning barely able to stand.  I guess that's a good thing.
