It sounds like you are doing terrific, especially since you are making a comeback from a back injury. This site seems to attract the most amazing people.

I dread cardio days after LBWO. The sore legs and then doing the cardio on an empty tummy just makes me not want to do it. But I always feel good when it's over. So I just keep telling myself I can do it. I did it last week and I can do it this week.
