Fitness Program Offerings


F45 Training (Functional 45) is a global fitness community specializing in innovative, high-intensity group workouts that are fast, fun, and results-driven. F45 is specifically designed to provide a functional full-body workout while improving energy levels, metabolic rate, strength, and endurance. The team’s mentality at F45 Training helps members transform their lifestyle physically and mentally while encouraging community growth and a no-ego attitude.

At the Ralph S. O’Connor Center for Recreation and Wellbeing, we offer three formats of F45.

  • F45 Cardio:These F45 workouts are designed to use different energy systems and to test your stamina and endurance. These classes specifically use plyometric movements, tempo, and timing to work the anaerobic and aerobic systems.
  • F45 Strength: These F45 workouts are designed for both building muscle mass and bone density. The strength classes use functional movements to build a solid base of functional strength and power.
  • F45 Hollywood: F45 Hybrid sessions highlight the best of both worlds! These workouts feature some of the favorite cardio, resistance, agility, and core movements for an epic burn that increases endurance, fires up the metabolism, and aims to improve overall strength.
