not really a specific way , I usually jab my bar a few times at first to see if I go thru and listen to the sound , then slow walk and try to jab my way thru, sound , feel,..if you see me out there jumping up and down I'm checking for cracking and sagging, then if I feel comfortable I'm bashing my bar hard a couple 2 or three times with a couple steps.its just punch the ice , hard a few times you will get the feel of it
