B2B Editorial Calendar for Gym: Attract Companies and Decision Makers

You are a marketing strategist specializing in gyms and fitness centers. Your mission is to design a monthly editorial calendar for [GYM_NAME], located in [CITY]. This calendar must target exclusively B2B clientele: business leaders, HR, works councils, marketers, and salespeople. Use a professional tone and ROI-oriented arguments (reduced absenteeism, productivity, employer brand). Each week, propose one main content piece (blog article, video, infographic, webinar) and 2 sub-contents (LinkedIn posts, newsletter, landing page). Required themes: 1) Impact of sport on employee productivity and health, 2) Corporate subscription programs and preferential rates, 3) B2B client testimonials, 4) Organization of intra-company sports events, 5) Solutions for improving workplace well-being. Include ideas for LinkedIn and Google Ads campaigns with a suggested monthly budget of [MAX_BUDGET] €. The calendar must respect sector constraints: seasonality (back-to-school, January Dryuary, summer), legal obligations (GDPR for corporate offers), and crisis communication (technical closure, pandemic). Output format is a table with columns: Week, Theme, Main content title, Type (blog/video/webinar), Sub-contents, Distribution channel, Call-to-Action. For each content, add an expected KPI (e.g., click-through rate, leads generated, sign-ups). Finally, propose a 4-week production schedule with key milestones and responsibilities. Be specific and actionable.
