Make My Sales Page Sound Native — Fitness Website Copy Review (ES / FR / PT-BR / PL)

I run a fitness brand with landing pages in several languages. The pages were translated from English using AI, and while the meaning is mostly correct, the copy doesn't always sound natural — a native speaker can tell it wasn't written by one. I need a native speaker to fix that. What I need: Read through my sales page in your language (one page, roughly 1,000–1,500 words) Correct anything that sounds unnatural, awkward, robotic, or grammatically off Make the copy read like it was originally written by a native speaker — punchy, natural, and persuasive, while keeping the same meaning and structure The tone is informal and direct (we address the reader as "you" / informal register), aimed at people over 40 who want to stay strong and mobile as they age Flag anything that doesn't make cultural sense or should be phrased differently for your market Important: This is marketing/sales copy, not a literal translation job — natural persuasive flow matters more than word-for-word accuracy I'll give you the current text; you return a corrected version (in a doc or however you prefer) Please keep product names as they are unless they sound wrong (I'll clarify which are brand names) Languages I'm hiring for (apply for the one you're native in): Spanish (neutral / Latin American preferred) French Brazilian Portuguese Polish To apply, please: Tell me which language you're native in Briefly, in that language, rewrite this one sentence more naturally so I can see your style: "Strong isn't behind you. It's just built differently now." Mention any experience with fitness, health, or sales/marketing copy Small, quick project per language — could lead to ongoing work as I add more content. Thanks!
