Tips before you film

Film from a steady angle

Set your phone on a tripod or bench at hip height, side-on to the movement. It makes form easy to see, and that’s why people watch.

Respect people around you

Don’t film other gym members without asking, and check your gym’s filming rules. Getting this wrong is a quick way to lose a membership.

Stay inside your expertise

Share what has worked for you, and avoid medical, injury or diet advice unless you’re qualified. Viewers trust honest creators more.

Questions

What gym content gets the most views?

Specific, useful videos tend to beat general ones. A video about one exercise mistake usually travels further than a generic “full body workout.”

I’m a beginner. Should I still post gym videos?

Yes. Beginner journeys are relatable and many viewers are at the same stage. Document honestly and leave the coaching to qualified trainers.

Can the generator give ideas for a specific type of training?

Yes. Try topics like “calisthenics at home,” “running for beginners” or “strength training over 40.”
