Did you know that the result of your diet and exercise is also governed by the rules of genes? Genetics play an important role in determining how big your muscles will grow and which part of your body loses inches firs. However, our elite personal trainer bank suggests you never get held back by this fact! Genes help you set realistic goals, and learn that we are not all the same. So, one exercise does not fit all, and a result you get is not necessarily the same as a different person's.
