The components of planks primarily involve engaging various muscle groups throughout the body. The main focus is on activating and strengthening the core muscles mentioned earlier - rectus abdominis, transverse abdominis, and obliques - to stabilize the spine and maintain proper posture during the exercise. Additionally, planks engage the glutes (butt muscles), quadriceps (front thigh muscles), hamstrings (back thigh muscles), deltoids (shoulder muscles), trapezius (upper back muscles), rhomboids (middle back muscles), and erector spinae (lower back muscles). These different muscle groups work together to provide stability and support during plank exercises while enhancing overall strength and posture.
