"I don't know what to post" is almost never true — it's that your ideas aren't written down yet. Here are the places they're hiding.
Mine your own best posts
Open your top 10 reels by views. Each one is a proven idea. Make the sequel: the next step, the opposite take, the mistake version, the "I tried it for 30 days" version. Winners tell you what your audience wants more of.
Answer real questions
Every DM and comment that asks you something is a reel. Screenshot it, answer it on camera. If one person asked, hundreds wondered.
Turn one lesson into five angles
Take a single thing you know and film it as: the quick tip, the story of how you learned it, the common mistake, the before/after, and the myth you want to bust. Five reels, one idea.
React to your niche
Agree loudly, disagree respectfully, or add the nuance everyone skips on a take that's going around your corner of Instagram. Opinion travels.
Keep a running list, not a blank page
The real fix is to never start from zero. Keep a note with 20 lines in it and add to it whenever an idea hits. Filming day becomes "pick one," not "think of one."
Don't let one idea become one post
A good idea deserves more than a single upload. The same video, cut a few different ways and tested on people who don't follow you, tells you which angle actually lands — and gets more mileage out of every idea you do have.
