3rd week of Agility. I still have some problems with squatting low enough and jumping with my tremendous mass... and I think our 8x8 is not big enough for my son and I both to do this but we are now only about 7hrs behind schedule! This was a great workout though even with my modifications. I don't like it so much but I did get a lot of cardio benefit and I'm sure I got some stability etc in the knees and worked the core. We are into Week 3!
