It's important to stretch after sport
1 - To stay supple
If you are incapable of touching your toes when standing, then stretching would be very beneficial to you. Regular stretching leads to better flexibility, and as result, better performance when you do sport. For example, for weight training, supple muscles are more efficient and will become stronger with time.
2- To slow your body down
Another advantage of stretching after sport: your body needs to slow down with calm movements. After intensive physical activity, such as a competition or race, it is important to take time to slow down and rest your muscles. By stretching, you give your body essential calm time: take 15 to 20 minutes, breath slowly and enjoy!
