A trainer's content week

Monday: post a push day split. Tuesday: a high-protein meal prep. Wednesday: a myth-busting reel. Thursday: a client transformation. Friday: supplement timing tips. Saturday: a mobility routine. Sunday: a mindset or recovery post.

That's seven pieces of content. Every week. The fitness algorithm rewards daily posting more than almost any other niche. Miss a few days and your reach drops. The trainers and gym accounts that grow are the ones that never stop posting.

Filming and editing seven videos a week on top of training clients, writing programs, and running a business isn't realistic for most people. But the content itself is simple. Fitness posts follow repeatable formats: four exercises, four meals, four tips, four mistakes. That's where the 2x2 grid comes in.

Why the 2x2 grid is a natural fit for fitness

Think about how fitness content is already structured. A push/pull/legs split has exercises grouped in sets. A meal plan has four meals. A "do this, not that" correction shows two pairs. A supplement stack has a handful of products.

The 2x2 grid format on lowkey viral puts four images in a single 1080x1920 frame with text overlays. Each panel gets its own title. It's the exact format fitness creators already use, just produced in seconds instead of hours.

Some example prompts that work well:

• "I'm Coach Mike, a personal trainer posting daily workout splits. Today's post is push day, 4 exercises." One movement per panel.
• "We're FormCheck, a form-correction account for lifters. This post is squat form, do this not that." Paired correct/incorrect panels.
• "I'm GarageFit, I review budget home gym equipment. This post: starter kit under $100, four essentials." Four products in the grid.
• "We're CleanEats Prep, a meal prep account for people who lift. This post is 4 high-protein snacks that actually taste good." One per quadrant.

Photo slideshows (2-10 slides, exported as individual JPEGs) suit content that needs more depth. A full day of eating with macros on each slide, or a 12-week program overview broken into phases. Slideshow caption styles like classic_bold, background_bar, or neon_glow match different brand aesthetics.

Your own photos vs. AI images

Fitness content lives and dies on credibility. If you are showing a client transformation, a meal you actually cooked, or your form on a deadlift, use your own photos. You probably already have them on your phone. Create a manual brief on the dashboard, upload your images, and let the AI write the hook and panel titles. The tool's value is the video format, text overlays, and rendering, not replacing your actual content.

AI-generated images work for conceptual and educational posts where a specific photo is not the point. "4 common squat mistakes" with illustrated examples, generic supplement category comparisons, or anatomy-style visuals showing muscle groups targeted. They also work when you are batching content ahead of time and don't have photos for every topic yet.

You can mix both in the same video. Own photo of your home gym setup in one panel, AI-generated image of a product you are reviewing in another.

Getting started on the dashboard

Open the dashboard and create a manual brief: write a hook like "Push day: 4 exercises you need," add panel titles for each quadrant, and upload your photos. Or type a prompt and let the AI generate five brief options with hooks. Pick one, swap in your own images where you have them, generate AI images for the rest if needed, render, and post. A single grid video costs as little as 5 credits total.

You can batch a full week of content in one session. Seven prompts, seven briefs, seven rendered videos. Maybe 20 minutes of work.

Scaling with the API

Gym chains managing social accounts for multiple locations and trainers who post across several platforms hit the same wall: manual content creation doesn't scale.

The lowkey viral API handles this. Generate briefs and render videos programmatically. A gym with five locations can produce location-specific content from a single integration. A supplement brand can create product comparison grids for every SKU combination. Or an OpenClaw agent can run the whole pipeline on a schedule without any manual steps.

API access requires a PRO or ULTIMATE plan. PRO gives you 10 requests per minute. ULTIMATE gives you 30.
