About

I'm Yosef. RTX.

Lifter, coach, flipper and the guy who made RTX Gym Sim. This site is where my coaching, my free tools and my game live.

My story

I wasn't born strong. I started at 147 lb and dropped 30 pounds down to 117 by learning how to eat right and train hard. Then I spent the next stretch building the muscle back the right way, all the way back to 147. Same weight on the scale, but a completely different body and a deadlift I'm proud of.

Along the way I started posting everything on TikTok: the lifts, the flips, the funny stuff, and the honest talk about what actually works. Friends started asking me to coach them, they got real results, and that turned into RTX Coaching.

What I believe

  • It's not complicated. Lift, eat your protein, sleep, walk. Do it every week.
  • Consistency beats motivation. Motivation comes and goes. Habits stay.
  • No shortcuts. I'm strictly against PEDs and drug use. Everything you see is natural.
  • Have fun with it. Training should make your life better, not take it over.
