Progress even though I've done no workouts!?!?!

I was at the local outdoor basketball park and there are 2 goals, one that is 9'10" and another that is 10'. I decided to try and dunk the 9'10"for the heck of it and I almost got it!! I got the bottom of my palm at the rim and got the ball over but it hit off the back rim. My guess was that I was about 2"from getting it. I had never been that close to dunking on that goal even before the back injury so I was super shocked. All the kids said "ohhhhh" cause they thought it was going down!! Of course I didnt have the camera rolling but hopefully I can get the dunk down and will be recording then.
