Stretching keeps the muscles flexible, strong, and healthy, and we need that flexibility to maintain a range of motion in the joints. Without it, the muscles shorten and become tight. Then, when you call on the muscles for activity, they are weak and unable to extend all the way. That puts you at risk for joint pain, strains, and muscle damage.

Here are 10 reasons why you should try stretching after your next workout:

• Reduce the risk of injury
• Helps with muscle toning
• Decrease in muscle stiffness and soreness
• Decrease in lactic acid build up
• Improvement of blood flow
• Reduces lower back pain
• Improvement in posture
• Increased energy and endorphins
• Releases mental anxiety and muscle tension 
• Increase flexibility
