etc

not being able to strike bellow waist

or to strike back

neck

etc

what is even changed by being able to strike those areas

it is just more body targets

hit and move

a powerful strike to the neck can disable an opponent instanteniously

sure it might require adaptation but why can you not spar with a friend and figure it out

if you boxed you already know how to hit and move against someone also hitting and moving

why can you not just apply what you already know to new body targets and new body weapons (i.e. legs)

boxing is not overly formalized, your mindset towards boxing is overly formalized

everything in martial training is a long road

from being able to strike legs

to being able to devastatingly strike them

is at least a 2-3 years of practice

but you are a boxer

you already know how to generate power

just figure out how to do it with legs instead of arms

you should have a serious edge already because you already know how to do it with your upper body

you should be able to generalize what you already know and pick it up more quickly

you have to try these things out

punching bags, pads

i remember one day i was boxing the bag as usual confident that im incredibly powerful striker

especially for my weight

you could go to a TKD school long enough to figure out what you need to know, then leave

until a pro came in and was literally blowing the bag away every strike could be heard 100 meters away

watch him and copy him

watch bas rutten and cro cop videos

bas rutten even put out a video on how to kick hard

he seemed as if he was hitting it not only with his entire body weight, but also the weight of all air behind him

there are so many things you could be doing that you are not

and if it isn't perfect, so what? refine it. you already said it's a long road, there you go

sounds like a plan

you clearly are not sufficiently motivated to be able to wreck people

or you would have already been doing these things

go on r/streetfights and look up videos of people beating the shit out of each other

search "kick" and look at all the videos involving kicks

you will clearly see some moves trash people instantly

then go look up what MMA fighters who are good at kicking do
