Build a gym member-retention system - a first-100-days onboarding sprint, results-tracking cadence, attendance-based churn-save triggers, win-back sequences, and a churn-impact calculator. Use when a gym owner says members are quitting, retention is weak, onboarding is ad hoc, a member wants to cancel, or they want to win back cancelled members ("reduce churn", "first 100 days", "save a member", "win back"). Do NOT use for general SaaS or subscription churn analysis - use churn-reduction instead; do NOT model CAC/LTV economics here - use gym-money-model.

# Retention and Churn Killer
Engineer gym member retention: onboard new members into a habit, make results visible, catch and save members before they quit, and win back the ones who left.
## Workflow
Run these steps in order. Skip a step only when the owner already has that piece working.
### Step 1: Engineer the first-100-days onboarding sprint
Early usage predicts tenure: the more a member trains in their first month, the more they value the gym. Make the start a fixed sequence, not a hope. Produce the onboarding-runbook below with a named owner and date for each milestone.
1. Day 0: send a welcome message, book the first session, send the plan.
2. First session: run a baseline scan, confirm the goal, deliver one guaranteed early win. The member should leave proud they came.
3. Week 1: get three sessions booked and attended, introduce them to the group, surface one measurable result. Frequency builds the habit.
4. Day 7, 14, 30 check-ins: a short, specific coach conversation about progress and obstacles - never a vague "how's it going."
5. Day 30: review a visible, measured result. This converts a trial mindset into a member mindset.
6. Day 60-100: re-scan, celebrate the trend, set the next goal so the member always has a reason to keep going.
