About Sondera

We built this because
the model was incomplete.

Most health and performance programs address what you do — eat this, move more, think differently. Very few address why those things keep not working. Sondera is built on the belief that the missing layer is physiology.

what we believe
Behavior follows biology.
Not the other way around.

Why stress stops weight loss and performance — and what to do about it

Sondera is a stress and performance coaching company built to address the complexities of the whole individual. The Harvard Grant Study — one of the longest-running studies on human happiness and health — found that true fulfillment doesn’t come from wealth, status, or achievement. It comes from emotional resilience, meaningful relationships, and living in alignment with your values.

That finding shaped everything Sondera is built around. Because the research is clear: stress physiology is the mechanism between intention and outcome. When your nervous system is chronically elevated, willpower, discipline, and good habits all become much harder to sustain — not because you’re weak, but because the biology is working against you.

Sondera is stress and performance coaching built on the belief that physiology drives behavior. Body, brain, and behavior as one system — not three separate problems to address separately. 

LEVER 1

Body

Resistance training as regulation

Progressive movement that rebuilds metabolic health, preserves muscle, and directly downregulates the nervous system. The primary vehicle — not an afterthought.

LEVER 2

Brain

Stress physiology as performance

Understanding the patterns keeping you in survival mode — not as therapy, but as a performance tool applied directly to health and behavior change.

LEVER 3

Behavior

Nutrition without restriction

A protein-forward framework built to survive a hard week. Because sustainable nutrition isn’t about discipline — it’s about fueling a body that isn’t running on cortisol.

the origin

“We kept seeing people who were doing everything right — and still stuck. The missing layer wasn't strategy. It wasn't habits. It was physiology they couldn't see.”

Sondera was built to address that gap — the stress physiology that makes behavior change so hard, and the movement science that actually rewires it. Not a mindset company. Not just a fitness program. A system for people who want to understand what’s actually going on — and do something about it.

Scott & Kristen Boss • Founders

Kristen Boss

Co-founder · Personal Development & Behavior Change

Kristen is a sought-after voice in personal development, known for her direct, no-fluff approach to helping high-achievers break free from burnout and self-sabotage. She previously built a large-scale coaching company that served tens of thousands — and became a trusted name in the industry.

Behind that success, she saw a deeper need: a company with a mission rooted in transformation, not just performance. A place where growth was about becoming, not just doing. She saw a deeper need — a burnout recovery program rooted in actual physiology, not solely mindset work. Sondera is that company.

Scott Boss

Co-founder · Leadership Development, Strategy, & CPT

Scott spent years running a high-output professional life — the kind where health gets managed around rather than addressed. Back injuries starting at 30. Kids who wanted to play, and a body that couldn’t keep up. Not a crisis. A slow divergence between who he was capable of being and how he actually felt.

The shift came from a family photo in 2021 — an honest look at the trajectory he was on and a decision about which version of the future he was building toward. What followed was years of working through what actually drives the pattern: not discipline, not information, but the stress physiology nobody had named for him.

He built Sondera Fit because nothing that existed addressed the actual mechanism. He’s a certified personal trainer and the operational architect behind how the program is built and delivered — and he’s been inside the problem long enough to know exactly what the solution needs to be.

What we built

The belief becomes
the program.

Sondera Fit is the direct expression of everything this brand is built on — a 12-week group coaching program that addresses body, brain, and behavior as one system. Not a fitness app. Not a mindset course. A framework for people who want to understand what’s actually getting in the way — and address it at the root.

The Mission

Built for the person who's done guessing why it keeps not working.

Most programs address what you do. Sondera addresses why the doing keeps failing and builds a system around the physiology that’s been working against you the whole time.
