Stretching exercises should ideally be performed at least two to three times per week to maintain flexibility and prevent injury. Regular stretching enhances the range of motion in joints, reduces muscle stiffness, and contributes to overall functional mobility. Incorporating stretching into a fitness routine promotes better posture and can alleviate tension built up from daily activities. Stretching is particularly important for individuals engaging in rigorous physical activity, as it helps prepare muscles for exercise and aids in recovery after workouts.
