This can be achieved through various methods, including stretching exercises, yoga, and physical therapy. Enhanced flexibility can lead to better overall physical performance, reduced risk of injury, and improved posture. Regular practice of flexibility exercises can also promote relaxation and stress relief. Activities like yoga and Pilates focus on stretching and strengthening the body, contributing to greater flexibility over time. Incorporating these practices into a fitness routine can benefit individuals of all ages and fitness levels.
