Adherence
Genetic testing for exercise prescription (e.g., predicting 'power' vs 'endurance' response) lacks sufficient scientific evidence and is not currently supported as a scientifically-sound approach.
Do not rely on commercial genetic tests to dictate your training program (e.g., whether you should do more strength or cardio work). The science does not currently support using DNA to prescribe specific training protocols. Focus on proven training principles and monitor your actual response to training.

Mainstream testing for personalized training or exercise prescription based on genotype is not currently supported as a scientifically-sound approach, although it is likely to be a common and viably employed coaching tool within the next decade
