If I could do it all over...

I will slap my 13 year old self and i will tell him to go and train every single day no matter how hard it seems.

 

I would incorporate Jeet Kune Do into my boxing training. Be like water.

 

As well as training to be prepared for any style. Pretty much don't close myself out to only 1 style.

 

Cement the basics and ensure I had a solid defence before trying to throw fancy combinations in short walk before I could run

 

I don't believe in "bad habits" as in it's supposedly better to not learn anything than to learn it wrong in boxing. I think bad habits are generally better than no boxing experience at all, the only exception would be whatever makes you more exposed to injuries like caveman training methods, hilariously bad punching techniques that can damage your hands or hard sparring.

Other than that I believe you can improve everything with time and unlearn all the bad habits. Especially considering that most of us here train it more as a hobby and not on the level of professionals so we don't need to be dedicated to strength and conditioning that much and we can afford to have a lot of training dedicated to technique. In fact, if you're not competing you even have the luxury to start certain techniques completely from scratch again at any point since you're not preparing for anything specific.

I think people use this "bad habits" thing as an excuse to not work harder and improve. They just say to themselves "oh I have these bad habits and I can't do anything about it anymore".

If you really want to "start all over" maybe you should switch the stance, for example if you're an orthodox who never uses southpaw imagine yourself as a complete beginner southpaw and start with the basics. It gives you the feeling of almost training boxing for the first time. Doesn't matter if you're right handed, Lomachenko and plenty of others are right handed southpaws. I did this over the summer, I was training only southpaw for a month and focused on doing everything correct technically in a way that I wasn't when I started training boxing as an orthodox.

 

I naturally tend to be aggressive but not an out of control type. I throw a lot of punches per round but have been learning to throw less punches and pic my shots better. I like to open a guy up with the jab then explode onto him. Kind of like a cheap version of Ray Robinson or Hagler. I like my coaches because they never pushed any one style on me. I usually work on all aspects of my fight game when training. Sometimes I'll take a week and just strictly box or fight on the inside just to get used to different situations.

 

Work on foot work, stance, guard

First 6 months i started with 5 of my mates every sparring session was a bloodbath. It was fun but didn't learn much apart from getting punched a lot. Black, eyes, broken jaws, fractured eye sockets, ambulances, fits, was mad really.

Dint think I ever sparred as much ever again.

 

Don't know about you guys, but great fundamentals.

It's hard to learn those though. Most trainers I've met might teach you the basics, but not well, and without the finer points. They don't emphasize the best things either. Ie I would train slipping outside WAY before slipping inside. A lot safer, and a lot better to learn angles, balance etc
