The Engine Inside You — ILSA Health Cardio & Conditioning DNA Test

Fitness DNA · 31 Genetic Traits

The engine inside you was built by your genes.

VO2 max. Heart rate response. Lactate threshold. Recovery rate. The size of your aerobic engine is part training and part genome — and the genome part is finally readable.

Why cardio plateaus

Your heart isn't lazy. It's wired for a specific kind of work.

Two people start the same Couch-to-5K. One trains into a marathoner. One quits at week four, exhausted. They didn't have different willpower. They had different aerobic engines — and the engine is genetic.

VO2 max — the gold-standard measure of aerobic fitness — is 50% heritable. Half of your aerobic ceiling was set the day you were born.

Some people respond to HIIT with explosive gains. Others gain nothing. The opposite is true for steady-state cardio. Both responses are predictable from DNA.

Heart rate recovery, lactate threshold, mitochondrial efficiency, blood vessel response — every dial that controls your cardio is genetically calibrated.

Your Training Modality

Does your heart prefer intervals — or a steady burn?

Every aerobic genome leans one way or the other. Train against your lean and you stall. Train with it and you compound. Here's what each pattern looks like on a heart-rate monitor.

BPM

0 min

30 min

The interval heart.

Explosive peaks. Sharp recovery.

If your genome favors HIIT, short bursts of near-maximal effort with brief recovery windows will transform your aerobic capacity faster than any other modality. Fast-twitch dominant, glycolytic, anaerobic-capable bodies thrive here. Long zone-2 work may feel like wasted time — and it often is, for this genotype.

The Cardio Blueprint

31 genetic traits. Six categories. The complete cardio engine.

Every dot is one trait we decode. Aerobic capacity, heart and vascular response, recovery, fat metabolism, strength backbone, and conditioning trainability — the full architecture of how your body does cardio.

Six categories. Thirty-one traits. One DNA sample. Every dimension of how your aerobic system trains, recovers, and adapts — decoded once and yours forever.

What you'll learn

Six revelations hiding in your cardio genome.

Hover (or tap) to flip each card. These are real examples of the kind of insight your cardio report will deliver — built from peer-reviewed exercise genomics research.

How efficient is your cellular engine?

Hover to reveal →

Mitochondrial Biogenesis (PPARGC1A)

Often called the master regulator of mitochondrial biogenesis. Different variants determine how readily your cells build new mitochondria — the ATP factories that power every endurance effort. The single biggest predictor of how trainable your aerobic system is.

Gene · PPARGC1A (PGC-1α)

How well do your blood vessels dilate?

Hover to reveal →

Vascular Response (NOS3)

This gene controls nitric oxide production — the molecule that widens your blood vessels during exertion. Certain variants mean better oxygen delivery to working muscles, lower blood pressure under load, and a higher aerobic ceiling. Some genomes have a built-in advantage here.

Gene · NOS3 (eNOS)

Are you wired to last — or to attack?

Hover to reveal →

Endurance Polymorphism (ACE I/D)

One of the most studied genes in exercise science. The I (insertion) variant is overrepresented in elite endurance athletes — marathoners, cyclists, even Mt. Everest climbers. The D (deletion) variant skews toward power and sprint athletes. Yours is yours.

Gene · ACE I/D

How much will training improve your VO2?

Hover to reveal →

Training Responsiveness (CKM)

Two people can do the exact same training plan and one improves twice as much. This gene predicts your response magnitude to endurance training — your "trainability quotient." It tells you how much room there is between where you are and your genetic ceiling.

Gene · CKM (Creatine Kinase Muscle)

Are you a fat burner in zone 2 — or a sugar burner?

Hover to reveal →

Fat Oxidation in Cardio (ADRB2)

The beta-2 adrenergic receptor gene shapes how readily your body taps fat stores during aerobic work. Some genomes are efficient fat burners — long sessions melt body fat. Others rely on glycogen and need a different strategy. Both can lose weight; the path looks different.

Gene · ADRB2

How fast does your heart rate drop after effort?

Hover to reveal →

Heart Rate Recovery (IL6)

HRR — how quickly your heart returns to baseline after exertion — is one of the strongest predictors of cardiovascular health and trainability. Inflammatory genetics shape it. Better recovery means you can train more frequently, with bigger compound effects over months.

Genes · IL6 · CRP · TNF-α

What Cardio Blindness Costs

The numbers behind training the wrong way.

Half of every cardio program is genetically wired. Working with that wiring — instead of against it — is the difference between transformation and plateau.

Who It's For

If cardio is your lever, this is your test.

The Cardio & Conditioning DNA test is recommended for weight loss and fitness training. It's especially valuable for these four people.

The runner, cyclist, or swimmer

You log the miles, watts, or laps. You want to know your true aerobic ceiling, how to time your peak, and how much room your genome actually has for improvement. This is the layer of precision your watch doesn't measure.

The HIIT or Peloton enthusiast

You love intervals — short sessions, big heart rate spikes, fast results. Knowing whether your genome actually rewards this style, or whether you'd respond better to a different mix, can multiply your effort.

The person on a GLP-1 protocol

Cardio is essential to preserve heart health and lean mass during rapid weight loss. The right modality, intensity, and frequency for your genome is the difference between losing 30 pounds well and losing 30 pounds poorly.

The person on a plateau

You've been running, riding, or rowing for months. The pace hasn't improved. The body hasn't changed. You're not lazy — your modality may simply be wrong for your genome. This is the test that ends the guesswork.

Questions, Answered

What you're probably wondering.

Do I need to be a runner or athlete to use this?

Not at all. The Cardio & Conditioning test is built for anyone using cardio as a lever — beginners, weekend warriors, GLP-1 protocol users, recreational runners, dedicated cyclists, and competitive endurance athletes. The deeper you train, the more precision matters. The earlier you start, the more years of better training you bank.

Will this tell me my actual VO2 max?

No. A real VO2 max measurement requires a lab test with a mask and treadmill protocol. What this test reveals is your genetic ceiling — the maximum VO2 max your body could reach with optimal training, plus the markers that predict how trainable you are. It's the upper-bound number rather than the current snapshot. Pair it with a real VO2 test if you want both data points.

Is this different from the Athletic Performance test?

Both use the same underlying 31-trait Fitness DNA panel, but the reports are framed for different audiences. Cardio & Conditioning emphasizes aerobic capacity, heart rate dynamics, mitochondrial efficiency, vascular response, and HIIT vs steady-state lean — the variables that matter most to runners, cyclists, swimmers, and conditioning athletes. Athletic Performance is the broader fitness frame. Pick the one that matches how you train.

Can I take this on a GLP-1 medication?

Yes, and it's especially useful. Cardio during rapid weight loss protects your heart, preserves lean mass, and shapes the composition of what you lose. The right modality and intensity for your genome makes that protective effect significantly stronger.

How accurate is the lab work?

The testing is performed in a CAP/CLIA-accredited laboratory with greater than 99% accuracy. Every interpretation is grounded in peer-reviewed exercise genomics research. Your DNA and personal data are kept secure and HIPAA-protected at every step.

Do I need to take this more than once?

No. Your DNA does not change. One test gives you a report that is yours, forever. As exercise science evolves, interpretations may be updated — but your underlying genetic data is a one-time investment.

How long until I get my results?

Approximately 3–4 weeks from the moment the lab receives your sample. You'll receive your full personalized report by email and through your secure online dashboard.

Where do you not ship?

Due to state regulations on direct-to-consumer genetic testing, we currently do not ship to New York, Pennsylvania, Rhode Island, or Maryland. Anywhere else in the United States is fine.
