Okay... So I've been experimenting now that I have a bit more time.
PART 1
==Practice Jab Fighting
As you may know already Jabbing is a very important part of boxing offensive/defensive/probing... Its the standard tool you really have to know how to use.
(I would suggest at least reading the manga Hajime No Ippo if you have any interest in this game and know nothing about boxing)

Now Freshmaker and others may have different opinion but this is what I came up with.
Assuming you are right handed you will be jabbing with your left hand.
Only use Jab for this practice its best to go into SPARRING mode for it so you don't worry about losing/winning.
*) Always start from a guarded position. I like Tyson's Peek-a-boo guard personally but just keep your hands up.
*) Jab from your left hand
--Practice getting full extension and speed into your punch
--Always return to the guard so that you can block strikes
*) Use the right stick as a joystick by holding the move button down
--move unpredictably
*) Probe the distance to the opponent in and out of attack range
*) Jab to the body and head both
*) Work on your footwork and head position to duck/bob/weave/slip attacks
*) See if you can work in a counter punch jab to throw off your opponent
*) work on jab combinations high and low
