StrideOne: why tracking internal health markers matters

Tracking steps, sleep, heart rate, and recovery has become second nature. Wearables have normalised monitoring how the body responds to daily life. But these tools only show part of the picture.

Internal health markers - including blood biomarkers, gut microbiome data, DNA insights, and biological age - reveal how the body is functioning beneath the surface. These signals often shift long before symptoms appear, offering an opportunity for earlier, more personalised action.

In this video, Andrew Steele, CEO and co-founder of Stride, explains why tracking internal health should be an everyday habit, not something reserved for moments when something goes wrong.

The limits of symptom-led health decisions

Most people engage with their health reactively. Action is taken once energy drops, performance declines, or symptoms appear. At that point, biological changes may already be well established.

This symptom-led model creates common problems:

• Root causes are harder to identify
• Interventions arrive later, when options are narrower
• People rely on generic advice rather than personalised insight

Internal biomarkers often change quietly, years before a condition is diagnosed. Without visibility into those markers, opportunities for prevention are missed.

Why isolated test results don’t provide clarity

Single health tests can be informative, but they rarely tell a complete story.

Blood tests show current biological status but not inherited tendencies. DNA testing shows predisposition but not real-time expression. Gut microbiome data adds context around digestion and inflammation but not systemic outcomes on its own.

When these data points are viewed separately, they can feel fragmented or even contradictory. When they are interpreted together, patterns start to emerge.

StrideOne was designed in response to this problem: not to add more tests, but to connect them.

What comprehensive internal health tracking involves

Effective internal health tracking combines measurement, interpretation, and follow-up.

This includes:

• DNA testing to understand long-term biological tendencies
• Gut microbiome testing to assess digestion, inflammation, and microbial balance
• Advanced blood biomarkers to track metabolic, hormonal, and inflammatory health
• Biological age to contextualise long-term health trajectory

Crucially, these markers are not static. Tracking change over time is what turns testing into insight.

Turning internal health data into action

Data alone does not improve health. Interpretation, context, and guidance matter.

Internal health tracking is most effective when results are reviewed together, revisited regularly, and translated into practical steps that reflect individual biology rather than population averages.

StrideOne brings these elements together into a single system, making it easier to understand what to support, what to monitor, and what does not need intervention.

Frequently asked questions

What are internal health markers?

Internal health markers are biological measurements that reflect how the body is functioning. They include blood biomarkers (such as cholesterol, inflammation, and nutrient levels), gut microbiome composition, genetic data, and biological age indicators.

How is internal health tracking different from wearable tracking?

Wearables track external outputs such as activity, sleep, and heart rate. Internal health tracking measures biological processes such as inflammation, metabolism, nutrient status, and genetic risk, which wearables cannot detect.

Why is it important to track health before symptoms appear?

Many long-term health conditions develop gradually. Changes in blood biomarkers, gut health, and metabolic function often occur years before symptoms are noticeable. Tracking internal health allows earlier, preventive action.

What is biological age and why do people track it?

Biological age estimates how the body is functioning relative to chronological age, using biomarkers linked to long-term health outcomes. It provides directional insight into health trajectory rather than a diagnosis.

How often should blood and gut health markers be tested?

Blood and gut markers can change over weeks to months in response to diet, sleep, stress, and lifestyle. Periodic retesting allows trends to be tracked and helps distinguish short-term fluctuation from meaningful change.

Can DNA testing be useful if you feel healthy?

Yes. DNA testing can highlight inherited tendencies and higher-than-average nutrient needs, even when someone feels well. When combined with blood and gut data, it helps explain how those tendencies are expressed in real time.

Does internal health tracking replace medical care?

No. Internal health tracking is designed to complement healthcare by providing earlier insight, better context, and more personalised support between clinical visits.

Conclusion

Wearables changed how people think about daily movement and recovery. Internal health tracking has the potential to do the same for long-term health.

By making blood, gut, DNA, and biological age tracking routine rather than reactive, StrideOne shifts health from symptom management to understanding. That shift makes earlier action possible and long-term health more intentional
