Model gym unit economics - Client-Financed Acquisition, 30-day cash, CAC, LTV, LTV:CAC, and payback - and return a verdict on whether growth self-funds. Use when a gym owner asks "what's my CAC", "how much can I spend to get a member", "what should my challenge cost to break even", "is my gym profitable to scale", "what's my LTV:CAC", or "why does growth stall when ads work". Do NOT use for generic SaaS or non-gym business unit economics - use unit-economics instead.

# Gym Money Model
Build this first. Every other gym growth skill spends money or sets a price, and
this model tells you whether that spend pays for itself. The goal is
Client-Financed Acquisition: the front-end collects enough cash in the first 30
days that each new member funds the acquisition of the next one, so growth is not
capped by the bank balance.
Work the example gym throughout: one location, semi-private coaching plus
memberships, a 6-week transformation challenge as the front-end.
## Operating procedure
Follow these steps in order. Do not skip to LTV before the front-end math is
clean, because a gym dies from cash timing long before it dies from lifetime
value. If the owner is setting the challenge price, pair with
gym-transformation-challenge; if setting an ad budget, pair with
gym-meta-ads-funnel.
