I hear some say inside fighting is only clinch fighting (chest to chest) and others say its mid-range (Joshua vs Ruiz 1)
Tons of stuff to do on the inside. Controlling distance/ range and angles. setting your opponent off balance by pushing your forearms into them, leaning, clinching, etc Utilizing different combos So to answer your question everything involved w being close to me is inside fighting.
Some exceptional fighters that excel at this are Roberto Duran, Henry Armstrong, and Joe Gans. They are all great at wrestling in the inside while fighting well mid-range.
Infighting is extremely complex and hard to categorise because it can potentially happen in so many different ways. I think an important distinction to make is the difference between a good clinch game, and a good inside game. They're not the same thing, but both similar and complimentary. Clinching is much more closely tied to grappling, wrestling and control, whereas infighting is punching, defence, exploiting openings and creating punch paths and avenues. You can be good at clinching without being good at infighting IMO - like Wladimir Klitschko. If you're looking to learn, ask at your gym. Someone there will be able to show you basic techniques and tactics in both the clinch, and upclose. They'll be able to show you your mistakes, the positions and proper way of doing things and talk you through it. Once you know how and why you're doing the basics, you can start to learn some more of the advanced stuff by either speaking to some of the more higher level fighters around your area, or just by watching studies/fights on YouTube. Obviously Duran is the guy to recommend for most, but Chavez's 'fundamentals first' approach is something which can work well for anyone. Anyone with an IQ of at least 3 should be able to tell the difference between 'infighting' and 'mid-range'. The names create themselves.
I would say that both descriptions are fairly wide of the mark. Infighting is a complete system of fighting, that involves every combination that is used in mid range fighting. What makes it different, is that it is done at a very close proximity, where your body ad that of your opponent, act as obstacles. Far from being based on clinching, a lot of it is aimed at countering clinching.
it is as Gazelle says at mid & close range, it is defensive aggression, in that you work and manoeuvre your opponent where you want him or would like him to be, forcing his reaction for you to capitalize on it, working short stabs at him, or more powerful hooks & uppercuts and even knowing when to step back or suddenly pull back for a devastating punch or combo of them to harm or hurt. it's smart boxing skills, often developed in defence first, but when applied with subtle skill and savvy they become an attacking advancement which only experience can develop. I mean, I think like fighting off the ropes, yet your the one doing the damage, or cutting off the ring and nailing that opponent in any which way he moves, meeting them head on and up close if they try to bull there way out of it... it's mid & close range as it occurs or you influence it. JCC was just the boss and it was often at cutting the ring and mid & close range punishment when you see it. Box/fighters or defensive masters, more so than long range boxers have it, yet I dare say there are a good few scientific fighters who can execute all necessary skills. It is experience beyond basic text book boxing that teaches it, or not.
For me, fighting inside is fighting close to the other person. That can happen with/to anyone. Sometimes neither fighter is skilled on the inside and both just want to tie up, get separated and get back to their preferred distance. Some like the inside and they are skilled at it. Good inside fighting encompasses a lot. Using angles, using the head and elbows at times or at least using them to make the opponent move where you want him, using short punches and learning to move your body to the left, right, or back from the waist, to make the punches more powerful, using "stabbing" punches to the body, particularly to the solar plexus, short uppercuts, hooks to the liver, keeping the front shoulder to the target and not "squaring up", using the hands, forearms, etc. to deflect punches, using the elbows to block punches to the sides, rolling under punches and not getting caught with uppercuts, keeping the chin down and using the shoulders for cover when punching, using the elbows and hands to push off or up...there are many other things that could be mentioned, but I'm always going to leave something out.
Toe to toe inside fighting requires an opponent willing to take part. Very rarely do you get it on the inside. Boxing ebs & flows, as such if you're not throwing on the inside, you're defending or getting hit. Occasionally there is a stalemate where both men are taking a breather up close and not using clinches. A competent opponent will always find a way to engage or reengage to their benefit. Rios Alvarado is a fairly good example., Alvarado breaking away to box at times though.
