X training day

Today was my first official cross training day. I did about 20 min of lifting before heading over to the elliptical trainer. I spent about an hour on the elliptical just because I wasn't busy and I felt pretty good. It went well. I do have to say, I am experiencing some low back pain. I am not sure what is causing it, but it has been bothering me the last day or so. I am hoping its just my back being sore from driving over 1000 miles a few days ago. Either way it is a little annoying because It makes me just worry that its going to get worse. Hopefully this is just a little issue that will go away soon. Either way, I am making sure to stretch before and after every workout to try to prevent injuries like these. Sorry for the short blog today! I worked for 6 hours and I am super tired! Night!
