Your body, just like anything else, has ways to communicate. Learn to listen to the warning signs before it gets too late.
Warning sign #1 - after a short ride a saddle sore shows up.
#2- start to feel crooked on bike.
#3- crash in CX race then sit in the car for 12 hours.
#4- power to the pedals just doesn't feel there. Still feel crooked on the bike.
#5- left knee starts to hurt.
I knew after warning sign #1, I should have gone to the Chiropractor, but I was/still am cheep. So, I ignored my body's signs that things were not right. It took until my left knee hurt to walk and still hurt while riding.
Today, I went to the Chiropractor and half of my lower body muscles were "shut off". I was crooked, weak, and sore. I have learned (again) my lesson. I will listen to my body and what it has to say.
