Hey can is it possible for someone to retain their body fat after 10 years of intense training? It's for a story I'm doing and I'm wondering if a bigger impression would be made if the person in question lost his body weight to show how hard the training was, or kept to emphasize his focus on skill over his health?
Everyone’s bodies are different and every type of training is different. People train for the same sports differently and have different physiques to show for it.
Both of these women are Olympic class champion weight lifters, both won gold in the 1999 Winnipeg PanAm games in their respective weight classes.
So many factors need to be considered, there’s no single “yes train at an undisclosed sport for ten years and you will absolutely have this one body type”. Is your character naturally an endomorph, ectomorph, or mesomorph? Because that hugely influences their body type at any fitness level. Is your character living in the woods and hunting for food? because if that’s the case they won’t be getting as many carbohydrates (or really nutrition in general) as characters living in walking distance of a grocery store and would likely develop a leaner, scrappier physique than they might have otherwise. Are they actively trying to achieve a certain body type or do they just care about training to be better at whatever this one sport you haven’t told me is. Are they focusing on getting bigger? Stronger? More agile? Faster? More Stamina? Even then, that’s just a starting point to help you research and gather references, there’s no be-all-end-all cookie cutter body type for a given sport.
