What to Expect from Our Strength Training Program

This isn’t your average circuit class. Our strength training program emphasizes:

  • Proper technique and form coaching to prevent injury and maximize gains
  • Progressive resistance training using dumbbells, barbells, kettlebells, bands, and bodyweight
  • Balanced muscle development, no overtraining or imbalanced routines
  • Full-body functional strength, so you feel stronger both in the gym and in daily life

Each class is built around a training goal (e.g., power, endurance, mobility) and can be modified to fit your fitness level.
