What videos work for a gym or a trainer
Thousands of accounts compete in fitness, so generic content (“5 ab exercises”) gets lost. It works better to speak to a specific audience: people returning to the gym after years off, people with three hours a week, people training at home. Each video should answer a question or bust a myth that audience actually holds.
The structure that holds up best in short form is: a hook naming the mistake or belief (“if you only do cardio to lose weight…”), an explanation in two or three sentences, and one simple action for the next session. The topics that raise the most questions tend to be rest, consistency, progression, warming up and habits outside the gym.
Nobody can guarantee a video will go viral. What does build an account is posting regularly, keeping a recognisable style and answering commenters' questions with new videos.
What Vaideo does well and what it doesn't
Vaideo writes the script, narrates it with a natural AI voice in English or Spanish, finds free stock images (or generates them with AI) and assembles the video with zoom, pan and animated captions. It's ideal for explainers: training principles, myths, grounded motivation, habits or your gym's philosophy.
What it can't do is teach exercise technique accurately: the images are illustrative, they don't show your floor or your coaches. For technique demos, film them yourself (you can add those clips in Vaideo Editor (free)); use Vaideo for the rest of your calendar.
There's no background music either. It usually matters in fitness, so add your own track in Vaideo Editor (free) or pick one in Instagram's or TikTok's editor when you post.
Health and promises: communicating responsibly
Don't promise transformations (“lose 20 pounds in a month”) or present stock images as your clients' results. Besides being misleading, it can clash with advertising rules and platform policies. Talk about process and habits, not ideal bodies.
The advice in a video is general. Note in the description that it doesn't replace an individual assessment and that anyone with an injury, pregnancy or health condition should check with a doctor or physio. Avoid recommending specific supplements or diets without a healthcare professional's input, and review every script: the AI can oversimplify.

Frequently asked questions
What should a gym post on social media?+
A mix of useful content (myths, habits, common questions), real life at the gym filmed by you, and news. Vaideo covers the explainer side well.
Can I teach exercises with Vaideo?+
It's not recommended. Images are stock or AI-generated and don't guarantee correct form. For technique, film your own videos outside Vaideo.
Can I upload footage of my gym?+
Yes, in Vaideo Editor (free). The AI doesn't use them when generating (you can replace any image with another stock or AI-generated one), but afterwards you can add your gym clips or photos in the editor.
Does it include music?+
No. Add it in TikTok's or Instagram's editor when posting, or in Vaideo Editor (free) with your own royalty-free music.
Is the advice in the script reliable?+
The AI usually gets general principles right, but it can make mistakes. Have you or your coaching team review it, and remind viewers it doesn't replace an individual assessment.
Which languages can I use?+
English or Spanish, with one natural AI voice per language. There's no voice selection or cloning.
How much does it cost?+
Free: 1 video a day up to 30 s in 720p, watermarked. One-time packs that never expire (5 videos for €5, 15 for €12, 40 for €25): each video up to 5 min in 1080p with no watermark.
