I have a few questions concerning genetics and how big of a role they play in weight lifting, nutrition, etc. (I am 16 years old and the people who I will talk about are the same age.) Because I have 2 friends with whom I workout and one of them works out 3-4 times a week does HIIT and eats very healthy yet has average results. My other friend does only weight lifting 2-3 times a week and has a crap diet/eats junk/fast food a lot yet still has amazing results.
I looked at this and questioned myself why would there be such a diffrence? Then I thought genetics maybe? So I ask: How big of a role do genetics play in weightlifting/nutrition?
