Flexibility training plays a significant role in fitness by enhancing the range of motion and preventing injuries. Improved flexibility allows for greater movement efficiency in various exercises and daily activities. It also aids in muscle recovery by promoting blood circulation to the muscles. Regular flexibility training can alleviate muscle soreness and stiffness, contributing to better performance in strength and endurance activities. Incorporating stretching exercises, yoga, or Pilates into a fitness routine not only improves flexibility but also supports overall body stability and balance.
