Quick session on the elliptical

I had my first physical therapy appointment at 3PM and had to leave work early. I spent a couple of hours there, first getting an evaluation and then doing some strengthening exercises. I went back home afterwards and sat down to get some work done. I had a conference call at 10PM and ended up working until 9 to wrap up a couple of things. I took a break and went by Club O for a quick session on the elliptical. I was only able to put in 30 minutes but I kept the intensity high the whole time. I was pretty much hammering for the last half and felt like I got a good workout, even though it wasn't very long.
