A DNA fitness test reads genes for recovery, power, muscle building, heart health, and tendon strength. What it can and cannot tell you about training.
Should You Get a DNA Test Before Choosing a Workout Plan?
Key Takeaways
- A DNA fitness test looks at genes tied to recovery, sprint and power, muscle building, heart health, and ligament and tendon strength.
- The results can point you toward the type of training your body may respond to best, and away from the type that may wear you down.
- Uran Berisha changed his own training from long-distance cycling to strength work after a DNA test, and he reports feeling better and tracking better heart data since.
- The science is real but still developing. Some genes are clearly linked to athletic traits, while genotype-based diet plans have not outperformed standard plans in a large trial.
- You test once, because DNA does not change, and the report works best when a coach or clinician turns it into a program.
You put in the work. You follow the program. And you still feel flat, sore for days, or stuck. It is easy to assume you need to push harder. Sometimes the program simply does not fit the body doing it. A DNA fitness test is one way to find out. This article is based on our podcast episode, What Your DNA Can Tell You Before Your Body Starts Hurting, with DNA practitioner and IFBB professional bodybuilder Carmen Tocheniuk.
What does a DNA fitness test measure?
A DNA fitness test reads genes connected to how your body recovers, produces power, builds muscle, handles cardiovascular stress, and holds up at the ligaments and tendons. Carmen Tocheniuk's fitness panel covers recovery genes, sprint and power genes, muscle building and muscle recovery, heart and stroke risk, and ligament and tendon strength. The goal is a training program suited to the person, which may also help prevent injury.
It is a cheek swab. You mail it back and results arrive in about two to four weeks. Because DNA does not change, you only ever do it once.
Can your genes really tell you how to train?
To a degree, yes. Certain genes have well-documented links to athletic traits. One of the best studied, ACTN3, produces a protein found in fast-twitch muscle fibres, and researchers have found different versions of it more often in elite sprint and power athletes than in elite endurance athletes [1]. How much a person's aerobic fitness improves with training also runs in families, with a large family study estimating that roughly half of the difference in training response is inherited [2].
So genetics shape how you respond to exercise. What a test cannot do is hand you a finished program. It gives you a direction. A coach or clinician turns the direction into sets, reps, distances, and rest days.
What happened when Uran tested his own DNA?
Uran Berisha, founder of Unpain Clinic, did a DNA test around 2019. At the time he was doing long-distance cycling, 100 to 120 kilometres on weekends. He could do the distance and had the power. But for two or three days afterward he felt off. Something that should have energized him was draining him.
His results suggested his body was built more for strength than for high volumes of cardio, and pointed to a gene related to how his body clears cardiovascular inflammation. He shifted toward strength training and cut back on long cardio sessions.
He has tracked his heart data with a wearable ring for several years. He reports that his heart health readings now sit a few years below his actual age, and he credits that to one change in how he trains. Results like this vary between individuals. The point is not the number. It is that one piece of information changed a routine he had been forcing for years.
Strength or endurance: what the report is really asking you to choose
A DNA fitness report will not tell you to stop doing what you love. It shows where your effort is likely to pay off. Here is how the two directions compare.
If your genes lean toward power and strength: Your body may build muscle and produce force more easily. Long, repeated endurance sessions may leave you drained for days, the way they did for Uran. Weight training, shorter intervals, and longer recovery between hard sessions may suit you better.
If your genes lean toward endurance and recovery: Your body may recover quickly from volume and hold up well to repeated aerobic work. You may find heavy strength blocks slower to progress, and you may benefit from keeping some strength work in for joint and tendon health.
If your tendon and ligament genes show weakness: You may be at higher risk for tendon irritation with sudden jumps in load. Slower progressions, tendon loading work, and attention to conditions like Achilles tendon pain matter more for you than for someone else.
If your cardiovascular and inflammation genes show risk: Your body may clear the inflammation of hard training more slowly. Recovery, sleep, and hydration become part of the program, not extras.
Why does a plan built for your genes stick better?
Carmen sees a mental shift when clients train from their own results. They stop second-guessing. They stop copying what worked for a bodybuilder or a magazine. They know the program is theirs, so they buy in, and in her experience the effort goes somewhere positive.
That matters because most people do not quit a program for lack of information. They quit because they do not believe in it. A plan built on your own biology is easier to believe in.
How to use a DNA fitness test without wasting it
- Do the basics first. Carmen is blunt about this. Sleep, real food, enough water, and regular exercise switch genes on. No report replaces them.
- Test once. A cheek swab, mailed back. Results in about two to four weeks.
- Read it with a professional. The report is data. A coach or clinician makes it a program.
- Match the type of training to your results. Strength, endurance, intervals, or a mix.
- Protect the weak points. If tendons or recovery show risk, build progressions slowly and add recovery tools.
- Track how you feel. Uran used a wearable. A notebook works too. The report is the starting point. Your body's response is the feedback.
What about DNA diet tests?
Carmen's company also runs a diet panel that looks at micronutrients, macronutrients, and eating behaviour. Many people find it useful for choosing foods and vitamins. It is fair to say the evidence here is more mixed than for fitness traits. A large randomized trial that assigned people to low-fat or low-carbohydrate diets found that their genotype pattern did not predict which diet they lost more weight on [3]. So a DNA diet report is best treated as one input alongside how you actually feel and perform.
What the evidence says
- The ACTN3 gene, which affects fast-twitch muscle, shows different versions in elite sprint and power athletes compared with elite endurance athletes [1].
- In the HERITAGE Family Study, how much aerobic fitness improved with a standard training program clustered within families, with about half of the variation estimated to be inherited [2].
- In the DIETFITS trial, a person's genotype pattern did not predict whether they lost more weight on a low-fat or a low-carbohydrate diet, which is a reminder that DNA diet reports have limits [3].
As Carmen said on the episode, "If you can learn one or two things about your body, it is worth it."
How does this connect to injury prevention at Unpain Clinic?
Training that fits your body is a form of injury prevention. So is treating the tissue before it fails. At Unpain Clinic, Uran uses shockwave therapy, which sends acoustic energy into tendons and fascia to stimulate the body's own repair process, both after injuries and to optimize tissue before a season. If your report shows weaker tendon genes, that kind of proactive care may be worth a conversation. We also use ddrobotec AI robot trainers to measure and train strength safely. Athletes who train hard and still deal with lingering pain often find the answer is in the tissue, not in trying harder, which is something we see often with athletes and chronic pain.
Frequently asked questions
What does a DNA fitness test tell you?
A DNA fitness test shows genes related to recovery, power, muscle building, heart health, and tendon and ligament strength. It points you toward the type of training your body may respond to best. It does not give you a finished program.
Is a DNA fitness test accurate?
Some fitness traits, like power versus endurance tendencies and how much a person responds to aerobic training, have solid genetic research behind them. Other areas, like DNA diet plans, have more mixed evidence. Treat the report as one input, not the whole answer.
How much does a DNA fitness test cost?
Prices vary by company and by how many panels you order. Contact the provider directly for current pricing. Because you only test once, the cost is spread across a lifetime of use.
Do you need to repeat a DNA fitness test?
No. Your DNA does not change. One cheek swab gives results you can use for life.
Can a DNA test help prevent sports injuries?
It can flag genes related to tendon and ligament strength and recovery, which may help you build slower progressions and add recovery where you need it most. Results vary between individuals, and no test removes injury risk completely.
Should I stop cardio if my genes say strength?
Not necessarily. Uran reduced his long cardio sessions rather than cutting cardio out. A DNA report shows where effort pays off most, and a coach or clinician can help you balance the two.
