I agree with Kenton and KJ....
In my opinion,
The foundation to prepare for Figthing are:
1, one has to be able to generate significant power. For the bottom line is shutdown the opponents.
2, one has to be able to sustain or absorb some amount of significant incomming power. For the bottom line is one will get hit.
3, One has to be able to response in action with sufficient speed. For no one will stand there similar to a woodern dummy and might even action in a speed as fast as one can.
4, The more one knows and master about the variaty of technics the better one chance is. Kick, punch, lock, throw, bounce..... those are the basic.
without a right or wrong answer. How much and How far has one been in the 1,2,3,4 preparation? Without knowing the answer and fantasy about figthing is flying blind. IMHO. (eventhough the above might not applied to some born great fighter or a natural.)
Not to even mention, to get into the issue of either one is generating a pushing paper box power or a shooting spinining curve trajectory basket ball power.. and more....
seriously, if one is practicing a V2 with the SNT, sun punch, dummy....etc and havent seen a V4. How the heck is one be able even to catch or stop an incoming basket ball? Not to mention even with V4 one might not be able always guarentee to sometimes....
But then, everyone has thier view in this free will world. and why not? and I can be wrong.
just some opinions.
