This 2-minute assessment analyzes your symptoms, lifestyle, and risk factors in order to find a solution.
"I was gassing on hikes I used to crush. Heart of Steel rebuilt the engine."
How old are you?
What does your endurance issue look like?
Do you have stress symptoms during the day? Like feeling tired, cranky, foggy, or moody.
How's your energy at 3pm compared to when you wake up?
When did you start noticing changes to your energy and drive?
What results are you expecting from this protocol?
Endurance isn't just cardio. It's cardiovascular chemistry.
Nitric oxide, blood flow, and mitochondrial output all set the ceiling on what your body can sustain. When those drop, your tank shrinks — regardless of how fit you are.

Analyzing your endurance signals…
Mapping the vascular and energy-system markers behind your stamina.
Do you have a family history of diabetes, heart disease, or metabolic issues?
These conditions share root causes with cardiovascular decline — insulin resistance, inflammation, and metabolic dysfunction. Family patterns help us identify your risk factors.
How often do you eat processed foods?
Processed foods contain additives that affect circulation, inflammation, and cardiovascular performance. Ultra-processed diets are linked to declining heart health.
