The best exercises for core strength include planks, bridges, squats, and Russian twists. These exercises engage multiple core muscles, promoting stability and improving overall posture. Planks, for instance, activate the entire core, while bridges target the glutes and lower back. Incorporating movements that require rotation, such as oblique twists, enhances functional strength, essential for athletic performance and daily activities. A well-rounded core workout should include both static and dynamic exercises to optimize strength and endurance.
