My wakeup HR was 56. I felt really good during my stretches and sit ups, and I enjoyed the 0.6 mile run, feeling fine at the end. I did 20 sit ups, using the "Runner's World" method instead of the "army" method. See http://www.leigh.org/running/stretching.html for pictures of the RW method. Before my accident I was doing 30-35 sit ups. When I first started running after the accident, I did 3 sit ups. So, doing 20 is a big step. That, plus my wake HR, shows that I am gaining strength.
