Top Longevity Markers To Track For Longevity Focused Women

For a long time, the longevity conversation has centered around men—male biomarkers, male performance, male aging curves. That era is ending. Women are stepping into the driver’s seat, and it’s about time we start tracking what actually matters for our bodies, our hormones, and our long-term health.

If you’re serious about living longer and better, these are the markers you need to understand—not casually, but deeply.

VO2 Max: Your Longevity Power Metric

If there’s one number that consistently shows up as a predictor of lifespan, it’s VO2 max—your body’s ability to use oxygen during exercise. In simple terms, it reflects your cardiovascular fitness and mitochondrial health.

Here’s the reality: VO2 max declines with age. For women, that drop becomes more noticeable after 35 and accelerates post-menopause if left untrained.

General ranges (ml/kg/min):

• 20s–30s: 35–45+ is strong

• 40s–50s: 30–40 is solid

• 60+: 25–35 can still be excellent depending on training

The goal is to continuing to exercise the muscle that is our heart to prevent decline.

How to measure it:

• Wearables like Oura Ring and Whoop give estimates (helpful for trends, but not absolutely accurate and fluctuate)

• Lab testing (gold standard): metabolic carts like PNOĒ or hospital-based cardiopulmonary exercise tests

• Performance labs or high-end gyms often offer VO2max testing now

It’s becoming easier than ever before to monitor your VO2max levels.

DEXA Scan: Bone Density & Visceral Fat Reality Check

Most women think about bone density after it becomes a problem. But we need to be thinking about it from a preventative lens.

A DEXA scan gives you:

• Bone mineral density (critical for osteoporosis/osteopenia risk)

• Lean muscle mass

• Visceral fat (the dangerous fat around your organs)

Why it matters:

• Women lose bone density rapidly during and after menopause due to declining estrogen, so it’s crucial to check this regularly starting in your 40s.

• Visceral fat increases cardiometabolic risk—meaning you could be “skinny fat” and be at high risk

When to start:

• Baseline: early 30s (especially if you’re proactive and want to get a strong start)

• Definitely by: 40–45

• Routinely once you’re in your 50s, especially if there are risk factors of osteoporosis, osteopenia, low bone density and fall/fracture risk.

This is one of the clearest snapshots of what’s actually happening inside your body.

Metabolic Rate: Know What Your Body Burns

Understanding your metabolism is foundational—but most women rely on the standard 2000 calorie per day recommendation. Your caloric needs change based off of age, phase of menstrual cycle, activity level and muscle mass.

There are two key numbers:

• Resting Metabolic Rate (RMR): calories burned at rest

• Active Metabolic Rate (AMR): total daily burn including movement

Why this matters:

• Under-eating can stall metabolism and wreak detriment to your hormones

• Overeating without awareness of what you’re consume leads to fat accumulation

• Precision matters more as hormones shift with age - meaning as estrogen declines, every single calorie counts on the body

Testing options:

• PNOE offers a breath test that looks at your resting and active metabolic rate (often available at wellness clinics or labs)

• Some advanced fitness centers or nutritionist offices offer metabolic testing packages

Once you know your RMR, nutrition stops being a guessing game. You can then begin to plan your macros more effectively for your active vs rest days.

Resting Heart Rate: The Underrated Lifespan Signal

Resting heart rate (RHR) is one of the simplest—and most powerful—markers you can track daily.

Lower isn’t always better, but generally:

• 60–70 bpm: average healthy range

• 50–60 bpm: strong cardiovascular fitness

• Below 50: often seen in highly trained athletes

What matters most is your trend over time.

A rising RHR can signal:

• Overtraining

• Poor recovery

• Illness

• Increased stress load

• Sympathetic “fight or flight” activation

It’s one of the earliest warning systems your body gives you. Pay attention to it. Most wearables are now including this data and it’s one of the best markers to monitor over time.

HRV: Your Nervous System Dashboard

Heart Rate Variability (HRV) measures the variation between heartbeats—essentially how adaptable your nervous system is.

Higher HRV = more resilience, better recovery, stronger parasympathetic (rest-and-digest) activity.

Lower HRV = stress, strain, or imbalance.

What impacts HRV:

• Sleep quality (arguably the biggest factor)

• Alcohol (even small amounts can tank it)

• Stress and emotional load

• Overtraining or under-recovery

• Hormonal fluctuations (especially across the menstrual cycle)

• Heat (temperature of the bedroom can act as a stressor on the body)

This is one of the best real-time indicators of how your body is handling life all at once. It is the key marker to monitor alongside resting heart rate to see how balanced and resilient your body is.

Biological Age: The Bigger Picture

Chronological age is fixed (the number on the birthday cake each year). Biological age is not (can vary month by month and year by year).

Biological age testing looks at:

• Inflammation markers

• Cellular damage

• Toxin exposure

• Epigenetic changes

• Cholesterol levels

• Glycemic control

It gives you insight into the pace at which you’re aging—not just how many birthdays you’ve had.

For women, this is especially powerful because it reflects:

• Hormonal transitions

• Lifestyle stressors

• Environmental exposures

Think of it as a report card for how well your body is holding up—and where you can intervene. I’ve seen plenty of women reduce their biological age up to 20 years (!!!) through managing their stress, changing their diet and getting to the root cause of their inflammation.

The Bottom Line

Longevity is about prevention.

Women’s bodies are dynamic. Hormones shift, metabolism adapts, and risk factors evolve over time. While I know monitoring everything at once can be overwhelming, I recommend starting small and continuing to learn more.

We’re given these bodies with no instruction manual for use. The best thing you can do is learn what makes it drive smoothly.

If I were to start from scratch, i’d begin in this order:

• Resting heart rate

• HRV

• VO2 max

• DEXA (this goes to the top of the list for ladies 50+)

• Metabolic rate

• Biological age
