Rev Abs Day 10 & 11: Feeling tighter

So I have been feeling tighter around the middle and my stamina is up during BJJ class. The mornings are not easy to get up to but my body seems to wake me up for it even before my mind gets a chance to complain. I was going to sleep in this morning and do the workout tonight. Instead I woke up 10 mins into my extended sleep and did the workout. I was sort of on auto-pilot which is good. I did the abs tonight after work and enjoyed them. Lots of application to sitting up in guard for BJJ. My only gripe is they are repetitive and lack of stretching.
