My Story

Hey, What’s Up! I’m Jason Yun! I created LBN Online because I was tired of repeating the same boring workouts over and over again. It was launched 12/29/10.

Following the same bodybuilding routine year after year from the age of 20 to 25 produced some awesome results that I was happy about at the time. Really strong (or so I thought) and really big (around 215-222 pounds at 5’10”) But what I didn’t expect was the dreaded plateau. I didn’t think it could happen to me! But it did! I had a complete lack of motivation. It was hard to even get myself to go in to the gym, and when I did it was the same routine– same weights, same sets, same reps, same results. I was brainwashed into thinking that bodybuilding style was the only way to train—- Thanks, Arnold!


But boy was I wrong, and boy was I happy when I found a new way of training. It started with kettlebells, and moved into resistance bands, then intervals, and playground training, and it has evolved ever since! I know that feeling of being trapped inside of a boring gym or workout routine. LBN Online Strength & Fitness Workouts smashes boredom and takes your fitness, health, and life to a new level of AWESOMENESS!


You never ever have to repeat a workout again— unless of course you want too! You pick your style of workout- we call them Genre’s. Much like music- Pop, Rock, Classic Rock, Soul, Hip Hop- except with workouts:

  • Beginner Training
  • Advanced Training
  • Kettlebell Khaos
  • Low Impact Training
  • Resistance Band Training
  • Abs and Core
  • Hotel/Travel
  • Body Weight Training
  • Challenge Workouts
  • 5:00 Workouts
  • Improvement Warrior Yoga
  • And more to come…….

And you get to workout with me 🙂 How fun!

My Story

I graduated from  The Ohio State University (03), with an earned Bachelor’s of Science degree in Sports and Leisure Studies with an emphasis in fitness, coaching, and recreation. When I graduated I moved to Louisville, KY for an internship with the University of Louisville and the Olympic Sports teams there. Mostly working with Softball, Women’s Basketball and soccer I absolutely loved it! And thought that I found my calling. And started figuring out what I needed to do to become a collegiate strength and conditioning coach.

Snag #1

You need a graduate degree. No biggie, right. So I applied to East Stroudsberg University in Pennsylvania. They had one of the best exercise science programs. I attended classes for 3 days. School has never been for me and I couldn’t do anymore school. So I dropped out. However, while I was there they did dedicate the Rocky statue in Philadelphia which I happily attended– one of the greatest days of my life.

Snag #2

Got a real job and got stuck for a while. So I moved back home, back in with my mom (everyone’s dream as an adult). Got a job doing collections but plans were to open up my own Strength and Conditioning business. But I got stuck in the 9 to 5.

Snag #3

Back injury. When I came back from PA, my back was hurting even more then normal from a deadlifting injury– herniated disc…… probably from all the time I spent in the car. So decided to take time off from lifting weights. Lost 72 pounds in 6 months, went into a major depression. The job of collections where I would call people and yell at them and they at me didn’t help matters. But in the end it all worked out, thanks to a program for anxiety and depression, and finding kettlebells (still me favorite implement to train with). I then opened up my business Yun Strength and Fitness Systems, LLC in October 2007. Called myself the Backyard Strength Coach, where I would go to young athlete’s and train them. But…. I never went to anyone’s back yard 🙂 lose weight with online fitness boot camps

So I then started In-home personal training, picked up two clients pretty easily but couldn’t get anymore after that. Toiled along training two clients and still doing 30 hours at my collections job, I then found Bootcamps.

Turning Point #1

Opened up my first Bootcamp program called Yun Fitness Bootcamps in July 2008. And it took off from there. Here is where I developed my craft of developing awesome, intense interval training workouts.

Turning Point #2

Met my future wife in class in October the same year. Got married 9/17/11 🙂

It launched 12/29/10 as The Look Better Naked Online Bootcamp. And the rest is history……. Workout History! I look forward to adding the best online workouts for you each and every month.
