A core class is a fitness session dedicated to strengthening and stabilizing the muscles of the core, which includes the abdominal, back, and pelvic muscles. Led by an instructor, participants engage in exercises that target these muscle groups to improve core strength, posture, and overall stability. The class typically includes a variety of exercises such as planks, bridges, twists, and other movements designed to challenge the core muscles from different angles. Core classes aim to enhance functional fitness, support the spine, and contribute to better body alignment. It's a beneficial workout for building a strong foundation for various physical activities and daily movements.
