March was the strongest membership growth month since last April. 61 new members joined — 38% attributed to the "Bring a Friend" promo. The promo cost $640 and generated an estimated $2,900 in first-month MRR — a 4.5× return worth repeating quarterly.

Class fill rate remains below the 80% target at 74%. Tuesday/Thursday 7am slots are consistently under 50% full while the 6pm slots hit 95%+ and turn away bookings. Capacity is being left on the table every morning.

Members who attend 3+ classes per week have a 94% 90-day retention rate vs 61% for once-a-week members. Nudging low-engagement members (currently 182) to add one more class per week is your highest-leverage retention action.

22 members on month-to-month plans have not checked in for 18+ days. Based on historical patterns, 60–70% are likely to churn in the next 30 days. Combined MRR at risk: approximately $1,540.
