About this tool
Build ready-to-paste AI prompts for gym membership offers, class descriptions, check-ins and win-back messages.
Gym Marketing Prompt Pack builds a structured AI prompt — role, context, task, hard constraints and output format — for the seven messages a gym actually sends: membership offers, class descriptions, member check-ins, win-backs, trial follow-ups, referral asks and social captions. Each prompt carries the real character limit of the channel you picked (160 for an SMS segment, 1024 for a WhatsApp template body, 2200 for an Instagram caption) and the true per-day and per-month cost of the package, so the copy that comes back cannot invent a price or overrun the field.

The 160, 1024 and 2200 character figures come from the GSM alphabet spec and the platforms' own published limits.
Per-day and monthly-equivalent figures are computed from your price and package length, so the model is told the numbers rather than asked to derive them.
Every prompt bans invented testimonials, health claims and hype vocabulary, which is where fitness copy usually goes wrong.
160 characters per segment when the message uses only the GSM 7-bit default alphabet defined in 3GPP TS 23.038. A single emoji or Devanagari character switches the encoding to UCS-2 and drops the segment size to 70 characters, so the same message can suddenly cost two or three segments.
The WhatsApp Business Platform allows 1024 characters in a message template body. Templates also have to be submitted and approved before you can send them, so write the copy with the approval reviewer in mind, not just the reader.
Show both and let the reader pick. A 12,000-rupee package over 90 days is about 133 rupees a day or 4,058 rupees a month, and the monthly figure usually lands better against the price of a competitor's monthly plan while the total keeps you honest about the commitment.
The prompts only generate copy. Sending promotional SMS to Indian numbers additionally requires DLT registration of your sender ID and template with the telecom operator, and consent handling under the applicable regulations. Check your compliance obligations before your first campaign.
