take care your joints and knees before workout

I did 10K running 25 years ago 。

 

 Now I do 10K walking everyday 。

 

I took this supplement 。

 

Glucosamine &Chondroitin。

 

This is a good  recommendation from my family doctor 25 years ago before I decided to do the running。

 

It protects my knees and my joints perfectly。
