What's past gamechanger?Larry cites Dan Jon's standards as:
He really dives in to how that stuff translates to sport. I'm worried that article will disappear someday, because I wind up referencing it a few times a year.
Personally, I think that it depends on what Steve Anderson would call "defining your level of participation". In otherwords, how much time energy and money are you willing to expend toward your goal? You can't expect to become Gordon Ryan by going to jits once a week, and not spending any money. You have to look at what you're willing to do and then set your goal in an appropriate fashion.
A better question than "standards" is maybe, what level of physicality do I need to be able to attend a combatives seminar and walk away better prepared. What do I need to be able to do physically to learn? And honestly, I think the answer is almost nothing. You can have serious physical limitations and attend a good instructors combatives class and walk away with more capability than you walked in with.
What do I need to be reasonably capable? Against who? I like to think of TPI's Todd. In which case I still need to do better.
