the question is where should i start learning about energy system training now there's a lot of ways you can answer this question but to start i would say the place to start is with breathing specifically with tolerance to carbon dioxide so for an evolutionary perspective we evolved in a much higher carbon dioxide environment and a much lower oxygen environment than what we live in now and we can see this from research on embryos and the environment in the womb that shows us the environment that existed long ago so we need to be able to tolerate higher carbon dioxide when we can tolerate more carbon dioxide our endurance improves massively and this is very very poorly understood and very poorly coached and it's a reason why unfit guys don't get fit no matter how much work they do sometimes now if the breathing is the issue if the low carbon dioxide is the issue almost everyone can massively improve in this area floyd mayweather is able to hold his breath for like five or six minutes he's able to spa for 15-20 rounds with his mouth taped lemonchenko like five-minute breath hold so success leaves clues 99 athletes are not being exposed to the kind of training that will get them to this point now there's things like oxygen advantage and state and you know bryan mckenzie's work uh patrick mcewen fantastic work and it's great that this stuff is front and center now it's being addressed at the same time i'm not seeing many coaches coming out of this with clarity that we evolved in a much higher co2 environment and we need to train the body the medulla oblongata that it's okay that we can tolerate a lot of carbon dioxide so when we get stressed we breathe a lot because that's what we needed to do a million years ago or five million years ago 100 million years ago i don't know in evolutionary terms when we were in this low oxygen high carbon dioxide environment it actually doesn't work in the modern environment when you blow off your co2 you get all sorts of negative health and performance effects okay so this is where i would start and it's the work of buteyko that i think you should really dive into if you want to understand insurance um personally i think a lot of the energy system stuff is kind of overdone i was always one of the fittest best runners in teams that i played in and you just do what you know what needs to be done you know practice your sport really hard be strong enough to be able to perform well in your sport be fast be powerful agile if your first one isn't good then your 10th one is going to be not much better and your 100th one is going to be terrible so make sure the first one is good if the first one is amazing then you're going to have space for endurance okay so the the thing to work on is movement efficiency movement quality power speed and then you know you can work on preserving that starting with that foundation of health that's really the way i would go at it a huge fan of increasing relative strength dropping excess body fat and then using tools like sleds and hills i'm a huge fan of as well so i hope that gave you something to support you there that question came in from uh patrick jude dawes
