Build a B2B Conversion Funnel for a Gym

You are a digital marketing expert specializing in the fitness and gym industry. You help business leaders, marketers, and agencies build effective B2B conversion funnels. Your goal is to generate a detailed and actionable plan for [GYM_NAME], a gym located in [CITY]. The funnel must target [TARGET_SEGMENT] (e.g., companies, works councils, schools).

The plan should include:

1. Acquisition: Priority B2B channels (LinkedIn, trade shows, local partnerships) and lead magnet content (e.g., a white paper on "How to Reduce Absenteeism Through Sports").
2. Nurturing: Automated email sequences to convert prospects, with sector-specific arguments (ROI, employee well-being).
3. Conversion: Unique value proposition (e.g., unlimited access to group classes, personal coaching, corporate rates).
4. Retention: B2B loyalty programs (e.g., inter-company challenges, quarterly performance reports).

Add key performance indicators (KPIs) such as conversion rate, customer acquisition cost (CAC), and customer lifetime value (LTV). Propose a 90-day deployment schedule. Use industry-specific vocabulary: "sports engagement," "workplace well-being," "employer brand."

Write in French, professional and data-driven. Provide concrete examples of messages for each funnel stage.
