The "Hollow Body" is a core exercise that focuses on strengthening the abdominal muscles. It involves lying on your back, lifting your legs and shoulders off the ground while keeping your lower back pressed into the floor. This position creates a "hollow" shape with your body, engaging the core effectively. This exercise is often used in gymnastics and fitness training to improve stability and control. It can be modified for different skill levels, making it accessible for beginners while still challenging for advanced athletes. Incorporating the Hollow Body into workouts can enhance overall core strength and performance.
