Balance board activities involve using a device called a balance board, which is a flat surface mounted on a fulcrum or a stable base. These activities help improve core strength, stability, and coordination by challenging the user to maintain their balance while performing various movements. They can be used for fitness training, rehabilitation, or recreational purposes. Common exercises on a balance board include squats, lunges, and push-ups, which engage multiple muscle groups. Balance boards are popular among athletes, fitness enthusiasts, and physical therapists, as they can enhance overall body awareness and prevent injuries by promoting better balance and stability.
