Briefly describe four main benefits of stretching before exercising
What will be an ideal response
Stretching can improve physical performance by increasing joint flexibility allowing the joint to move through a greater range of motion. Stretching decreases risk of injury by decreasing resistance in various soft tissues so there is less of a chance of exceeding maximum tissue extensibility during activity. Stretching can reduce some of the muscle soreness that results after exercise. Stretching can help realign soft tissues to improve and maintain good posture.
