Exercises beneficial for improving core strength include planks, bridge exercises, and Russian twists. These exercises target multiple muscles in the abdominal region, back, and pelvis, which are vital for stability and balance. Incorporating activities like yoga and Pilates also supports core strength by engaging the muscles in controlled movements. A strong core is essential for overall physical performance, as it is involved in nearly all forms of movement, helping to prevent injuries and improve posture. Strengthening the core ultimately enhances functional fitness and athletic performance.
