your DNA will respond but you have to have serious intent, which is difficult to fake. If you wish to improve yourself physically, your DNA will respond, gradually, as long as you are serious about your intent. The more focused your mind is, the greater the effect.

Humans inability to concentrate and focus is what prevents this process from working perfectly....at a higher vibration, human DNA and work consciousness work perfectly...you can manifest instantly....at this lower vibration, the things you want come incrementally.

The key is to have an absolutely clear, perfect mind, which is almost impossible for an ordinary person at this vibration to do. Just be calm and focused and keep practicing.
