Flexibility training is significant in a fitness routine as it enhances range of motion and promotes joint health. Incorporating stretching exercises can help prevent injuries by improving the elasticity and resilience of muscles and connective tissues. Flexibility training also aids in muscle recovery post-exercise, reducing soreness and stiffness. Furthermore, improved flexibility can enhance athletic performance, allowing for more efficient movement patterns. Overall, regular flexibility training supports overall fitness by facilitating better functionality and physical performance during various activities.
