Introducing LX90

A 90-day program designed to help high-achievers burn fat, build muscle, & reverse biological age.

What’s up, I’m
William Bosch.

I work with ambitious professionals who want to slow down aging, boost vitality, and build bodies that match their drive—without sacrificing their lifestyle.

Over the last decade, I’ve built and scaled multiple health and wellness brands, including Iconic Protein, a nationally recognized company that helped millions fuel their day with clean, functional nutrition.

But eventually, I turned the lens on myself—applying everything I knew to reclaim my own health. The result?
I reversed my biological age by 7 years.

That personal transformation became the foundation of LongevityX—a premium health coaching experience for high-achievers who want to unlock next-level performance and longevity, starting now.

And believe me, getting here was a journey.

What Our LX90 Clients Are Saying

Real feedback. Real results.

"I dropped 5 years off my biological age, lost 20 pounds of fat, and got my energy back—this program changed my life"

Leah

“I’m wearing pants I haven’t worn since highschool. LX90 was the system that tied it all together.”

Ronnie

“Super responsive and always ready to help. The screenshots of our chat show just how easy Phil makes it to communicate.”

Ava P.

I recently completed the LX90 program, and I can confidently say it has been a transformative journey toward health, wellness, and truly aging backwards. The program is thoughtfully designed to equip you with all the tools needed to create a sustainable, healthy lifestyle. What stood out most was how seamlessly the program flowed—from start to finish, the structure was incredibly well-paced. At no point did I feel overwhelmed; each step built upon the last in a way that felt natural, supportive, and easy to follow.


A huge part of my success in this program was due to the incredible support from Coach Billy Bosch and Dr. Emil. They led with the utmost professionalism and a non-judgmental grace that made me feel both seen and empowered. Their guidance was always rooted in compassion, yet they held me accountable every step of the way—a rare and powerful combination.


If you're looking for a program that not only focuses on wellness but helps you reframe the aging process through a holistic and supportive lens, LX90 is it. I can’t recommend it enough. Plus the 20lb drop in weight definitely was an amazing benefit!
