Allow me to introduce myself or re-introduce myself to any new or old followers.
My name is Jason Yun and I am the Improvement Warrior Mitochondriac.
What the hell is that? Improvement Warrior was something I coined back in 2013 in what I now finish all my videos with the saying "Stay Strong, Stay Positive, be the Improvement Warrior!"
I changed the name of my fitness trust (i.e. I don't own a 'business' anymore ;) IYKYK) from Yun Fitness Bootcamps to Improvement Warrior Fitness.
An Improvement Warrior strives to improve just a little bit everyday in multiple areas of life. Are there stumbles? Always, but those are learning slips. Adapt, get stronger/wiser and move forward.
A mitochondriac is someone who focuses their health around the mighty mitochondria. A normal person’s weight is made up by ~30% mitochondria. Specifically we are focused around light, water, and magnetism--the 3 laws of nature. Your circadian biology matters more than food and exercise. If you have health issues then it is guaranteed your mitochondria is not functioning at full capacity.
I can certainly help you with your fitness/strength and nutrition but it really won't matter long term if your circadian health or mitochondria is broken.
My goal is to bring you to ultimate health for the rest of your life. Healthy people are not fat. Healthy people don't run out of energy. Healthy people don't need sleep aids. Healthy people don't need prescription drugs…Healthy people don’t have diseases……. And on and on.
Where should you start? It all depends where you are now. Life isn't a game. Time moves fast. And it moves faster for the sick and diseased.......and it's not as fun.
HEALTH IS THE SLOWEST FORM OF DEATH
When you are ready........reach out. We have a new group starting the 2nd week of April for 91-Days of Routine Fixing. Comment ROUTINE or dm for details.
I'm always happy to answer any questions or guide you to the right information until you are ready.
Most of my posts on here usually end with a hashtag. If you want to go down a rabbit hole on certain topics click it.
Stay strong, stay positive, be the Improvement Warrior!
