This is StRest! In this episode, Kerstin Lindquist is joined by human performance coach and functional health expert Justin Roethlingshoefer for a masterclass in reclaiming your health, energy, and God-given purpose.

They explore the insidious ways modern life steals your vitality—from glorifying hustle to normalizing poor sleep and ultra-processed foods—and how the right data can help you take your health back. With over 20 years of experience training elite athletes and high-performers, Justin breaks down the four key health metrics that determine cellular vitality and long-term resilience.

You’ll learn how to interpret and improve heart rate variability (HRV), VO₂ max, sleep quality, and cellular nutrient absorption, as well as how to avoid the trap of “normal” labs that overlook what your body really needs. Rooted in faith, science, and ownership, this conversation is both deeply spiritual and relentlessly practical.

If you’re a parent, leader, creator, or just someone trying to stay sharp in a distracted world, this episode will help you tune out the noise, listen to your body, and live with intentional obedience.
