Create AI fitness characters such as coaches, athletes, and gym creators, with defined physiques, natural skin details, and a consistent outfit and color. Prepare a character sheet for workout scenes and video, using catalog-style descriptions for activewear prompts.
Makes AI fitness characters on varg (coaches, gym creators, athletes, bodybuilders) with real muscle and skin, a locked signature outfit and colour, and catalog-style wording that gets sports bras, leggings and shirtless athletes past false moderation blocks. Builds the character sheet ready for workout scenes and video. Use when someone asks for a fitness influencer, gym girl or gym guy, a trainer for an app, an athlete for an activewear or supplement ad, or a character in a sports bra that keeps getting blocked. Part of varg-character-design (definition, sheet, reuse in video).

The natural home for activewear, supplements and fitness apps. "This fitness coach doesn't exist" (the post claims 8M views) locked one look: grey tee, dark joggers, lime wristbands. Contrast versions spread further: a skinny kid lifting heavy (every reel above 892K), an 80s bodybuilder with a mullet (9.1M).
The hard part is moderation: a woman in a sports bra at the gym is ordinary content, but short prompts get blocked. The catalog wording below passed on all six image models we tested.
Sheet, crops and video: varg-character-design.
Definition: adult age as a number + a role (CrossFit coach, yoga teacher, powerlifter, runner, physio) + one signature colour.

Clothing, named like a product listing (this is also what passes filters):
Activity, always: mid-set of kettlebell swings, deadlift lockout, a plank, stretching after a run. An activity reads as fitness; standing and posing reads as something else.

| Mara (tested) | 31-year-old adult woman, CrossFit coach, 172 cm, athletic muscular build, light-brown skin, short bleached buzz cut, a small scar through her left eyebrow, wide friendly smile; high-support lime-green sports bra, high-waisted black 7/8 leggings, black training shoes, black lifting belt, chalk on her hands |

Activewear brand catalog photo of a <age>-year-old adult woman with an athletic build, wearing a
high-support <colour> sports bra and high-waisted <colour> leggings, unbranded, mid-workout in a
sunlit concrete gym, holding a kettlebell at chest height, light sweat on her forehead, focused
expression. Natural skin texture with visible pores, real muscle definition. Shot on 35mm,
fitness magazine editorial.
Tested on nano_banana_2_1, gpt_image_2_5, seedream_5_pro, flux_3_image, soul and grok_imagine_image_2: passed on all six, and all six looked like real athletes. "Beautiful girl in a sports bra at the gym" was blocked on GPT Image 2.5; "hot sexy girl in a tight sports bra … big booty" was blocked on GPT Image 2.5 and FLUX 3 and came back as a plastic "AI girl" elsewhere.

Make each workout as an approved still, then animate it with kling_v4 (creators use Kling for gym motion). Veo blocks more fitness clips; Seedance strict tiers reject photoreal face references, so for Seedance use the stills, not a face sheet.

Plan worthwhile local tasks by checking dependencies, effects, resources, and platform boundaries, then execute the exact approved plan. It can use safe parallel work or suitable Apple-silicon backends when the project exposes them.
Turn a winning TikTok or Meta ad into a structured creative test plan. Identify what made it work, plan distinct concepts, set test budgets and review timing, and use funnel metrics to decide whether to stop, iterate, or scale each ad.
Record deferred engineering decisions and temporary workarounds in a debt registry, with context such as effort, ongoing cost, affected area, and payoff trigger. Entries receive short labels so they can be reviewed or dropped later.
Generate or compare AI agent code for LangChain, EINO, AutoGen, AgentScope, and CrewAI using framework-specific templates, API mappings, conventions, and project structures. Reference files include verification dates to help identify potentially outdated guidance.
Investigate a reproducible bug, test failure, or unexpected page behavior, then make a narrowly scoped fix. The workflow calls for a regression test before changing code, verifies the fix, and reports remaining risks and evidence while avoiding unrelated refactoring or feature work.
Build an AI agent project through six collaborative stages, from requirements and architecture to tools, prompts, code generation, and verification. Start framework-independent, then generate a runnable project for frameworks such as LangChain, EINO, AutoGen, AgentScope, or CrewAI.
