So I did a class on Saturday at the Y, Tabata.  I have taken similar ones at Befit before.  It was a good workout, I was tired when the hour was done.   My arms are sore today.  Not looking forward to the weigh in on Saturday, cross your fingers for some kind of loss.  I have been working on a 30 day plank challenge. I started before we left for vacation and got away from it, but I started over with it so we will see how it goes.
