Distance when punching your opponent?

[Von Milash]

Should I be wrist length or knuckle length from an opponent before throwing a jab or cross? Also, how many different ways are there to throw a jab and how would you execute them correctly?

knuckle is always better, but wrist can be effective too. It depends on your intercoastal muscle make-up. Also, are you using the Isringhaussen method?

as far as types are concerned, there are approximately 1300 different ways to throw a jab. I say approximately because some governing bodies recognize some methods while others do not. The IBF and wBC tend to be the strictest in this regard, while the WBO is quite lenient.
