I have worked on flexibility too. I can't raise my foot that high LOL so I need to start working on it more and more. That is my goal for spring...to be able to mount flat footed as my boy is a little flummoxed by a mounting block! LOL he will stand still for me to mount out in the field or anywhere but you put a mounting block by him and he will turn his butt away from it. He is just not used to it!
