Anyways, Yesteday was a cross training day. So I did a 10 minute ab workout on the t.v. with my aunt, and followed that up with a 15 minute cardio workout on there as well. Those two actually kicked my butt. I was very impressed with the intensity level of those two. After I finished with them, I went downstairs and did the Chest and Back day from P90X. Because I am currently trying to slim up, and improve cardio fitness instead of making muscular gains, I sort of cheated and skipped some of the intense moves, only because I didn't want to wear myself out in the wrong way for marathon training.
Overall my workout went really well. I felt great about the ab and cardio workout, but I think the chest and back one might have been too much on top of it for the day. I need to be careful not to over do this too early. I don't want to start with a bang, fizzle out, and end up not going the distance on this plan.
