High knees are a simple yet effective exercise that involves running in place while lifting your knees as high as possible. This movement engages your core, legs, and cardiovascular system, making it a great way to warm up or add intensity to your workout. To perform high knees, stand tall, then jog in place while driving your knees up towards your chest, alternating legs quickly. This exercise can be done anywhere and requires no special equipment, making it perfect for home workouts or outdoor training. Incorporating high knees into your routine can improve your endurance, agility, and overall fitness level, helping you achieve your health goals.
