Are fitness DNA testing services reliable?

Would a fitness DNA test help me get in better shape than just sticking to a random workout routine?

One’s fitness depends on a balance between nature and nurture.
DNA fitness testing is growing in popularity. These tests usually allows you access to a personalized training plan that is ideal for your genetic nature.
For example, if your test results show that you are prone to injury in specific areas or have longer recovery time from intense training, your PT can create a routine for you, keeping this information in mind.
