Gym Mirror Selfie Etiquette

• Keep other members out of the frame. Not everyone wants to appear online.
• Don’t block equipment. Take the photo between sets, not while someone waits.
• Avoid locker rooms. Photos are not allowed in most changing areas.
• Keep it quick. A few shots are plenty.
• Ask before tagging. If a friend is in the photo, check first.

Caption Mistakes to Avoid

• Lecturing your followers. A caption is not a workout plan.
• Overusing hype words. Too many “beast mode” lines start to sound like an ad.
• Posting a caption that doesn’t match the photo. A rest-day line under a heavy-lift photo feels off.
• Writing a paragraph. Under ten words usually reads best.
• Putting yourself down. A joke on yourself is fine, but harsh self-criticism isn’t a caption.
• Copying the same line every week. Change at least one word so it sounds like you.
