If I want to build strength and increase muscle mass, I should be during a high-volume form of resistance/strength training with 16-32 sets per workout and 12-15 reps per set. How do I know this? My genes told me.

You see, it all started with FitnessGenes and some spit. How does it work exactly? They send you a test kit and you send them your saliva. From there, your sample is sent to a lab in the UK to be processed and your DNA is extracted. From there, your results are analyzed and you receive an e-mail to log in to your profile, where you get detailed fitness and nutrition recommendations based on a combination of your lifestyle profile and your genes.

The results are detailed. There were 41 separate detailed results outlined in my profile, from the gene for endurance to the gene for vascular function and more. Each result is broken down in an easy-to-understand way (so, if you never studied genetics, don’t worry).

From there, FitnessGenes offers free training strategies and, should you want to take it further and be guided, optional training and nutrition plans you can buy. Should you not be ready to make that investment, however, the amount of information provided from the test is more than enough to get started on your own and receive the free guidance available.

To just receive the DNA Analysis, it is $199. The information you receive can not only help you devise a training strategy or guide you as you get started in a fitness plan, it can also actually benefit your overall health and wellbeing. For example, I learned that I should monitor my saturated fat intake, because I have two copies of the allele associated with a higher BMI in response to a diet consisting of high levels of saturated fats than other genetic variants.

So if you’ve spent time unsuccessfully trying to determine what training program works best for you, the answer could have been inside of you all along.
