Which types of exercises improve balance and stability?

The correct answer focuses on exercises that specifically target improving balance and stability, which are vital components of physical fitness. Yoga and Pilates are well-known for their emphasis on core strength, body awareness, and controlled movement, all of which contribute significantly to enhancing balance. Through various poses and flows, these practices challenge the body's stability and promote better coordination and proprioception.

In addition, specific balance drills—such as standing on one leg or using balance boards—are designed to improve the body's ability to maintain a stable position. These activities engage the muscles that are essential for balance, including those in the core, legs, and lower back.

The other choices include activities that primarily focus on cardiovascular fitness or strength training. While running, cycling, weight lifting, and speed walking can have some secondary benefits for balance, they do not specifically target balance improvement to the extent that yoga, Pilates, and dedicated balance drills do. Therefore, incorporating yoga, Pilates, or balance drills into a fitness program is the most effective way to enhance these skills.
