Chase Tomseth has spent 21 years as a personal trainer and a decade as a Brazilian Jiu-Jitsu black belt, and in that time he's learned the biggest barrier to getting fit was never the workout — it's the story we tell ourselves. In this conversation, Chase and Katiuscia dig into what actually drives lasting change: why “I can't” is almost always “I don't want to,” why the bathroom scale can lie to you, what it really means to be fit (hint: it's five things, not one), and why he'll fire a client before he'll let them stay stuck. They also get personal — Katiuscia opens up about training through an autoimmune illness and why strength became her survival tool, not just a hobby.
Whether you're just getting started or you've been chasing the same goal for years, this conversation is a reset on what fitness is actually for.
Pull up a chair. This is a conversation worth having.
