What duration is suggested for flexibility training during the final cool-down?

The suggested duration for flexibility training during the final cool-down is typically around three to four minutes. This timeframe allows for an adequate amount of time to effectively stretch major muscle groups that have been used during the workout. Stretching within this duration helps in promoting relaxation, enhancing blood flow to muscles, and aiding in the recovery process after intense physical activity. It is essential to hold each stretch for a period of time (commonly 15 to 30 seconds) to achieve the best results in terms of improving flexibility and promoting muscle recovery. This duration strikes a balance between being long enough to reap these benefits without extending the cool-down phase excessively, which could lead to diminishing returns in the context of a fitness class.
