Which muscles are primarily engaged during exercises that target the core?

Exercises that target the core primarily engage the abdomen muscles. The core is defined as the group of muscles in the trunk that stabilize the spine and pelvis, and it plays a crucial role in almost all movements of the body. The abdominal muscles, including the rectus abdominis, obliques, and transverse abdominis, are specifically designed to provide stability, balance, and movement efficiency.

When performing core exercises such as planks, sit-ups, or Russian twists, the abdominal muscles contract and engage to support the spine and maintain proper posture. This engagement helps in transferring force and controlling movement in the limbs, which is essential for athletic performance and daily activities.

While the muscles of the back, arms, and legs play important roles in various exercises, they are not the primary focus when it comes to core-targeting activities. The back supports posture and spinal alignment, arms are often engaged for movement support, and legs are crucial for locomotion and stability. However, the specific engagement of the abdominal muscles is what defines core workouts.
