It determines genetic potential, but the environment and diet that your more recent ancestors and you have developed in determines the expression of that potential.
Europeans across the board, north and south, were pretty short from the early industrial age until pretty recently, some time after ww2. Rural Americans were the tallest in the world because they had a superior diet and lifestyle to urban Americans and Europeans, while having the same genetics. Now, it's the opposite. Americans have the worst diet of any western country, as a result, white americans despite being mostly of germanic stock are shorter than Southern Europeans today.
And it's not just size, it's robustness too. If you want a good example of diet and environment influencing how well built people have the potential to be vs how they are, look at east asia. East asians are another arctic derived race. Actually, both east asians and the yamnaya share paternal ancestry with tianyuan man. They're not supposed to be as lithe and skinny as they are, but they've eaten a diet of primarily milled rice for the past several thousand years. Mongolians and turkic people show the actual genetic potential of northeast asians.

yes, hunting screened for (applied evolutionary pressure) endurance, eyesight, coordination, strength.
things change, things circle back around. right now, white men (white Y chromosomes) are undergoing a genetic filtering event, a genetic bottleneck. do what you need to do.
