YES please listen to this. THe past two years my ski seasons have been interrupted about every 3 months by an injury in my hip. Since i barely ever stretch all the muscles, especially in my left leg are sooo tight that they pull down my pelvis and the hip flexor muscles out of position. Doing this pinches the huge nerve in my left leg, making my whole leg have hella bad shooting pain everytime i walk, so i can barely walk, run, play soccer, skateboard, and most important SKI. Right now my mountain is open with hella powder, and i CANT SKI cause my leg is hurt so badly. So please stretch, stay healthy, and don't get stuck with my chronic injury, cause the only good thing taht comes with it is more chronic usage to relieve the pain....
