To start off---i have previosuly had some lower back problems in high school and college due to weightlifting, working construction, being in marching band.
One of the reasons i got into cyclign was that it seemed to alleviate my intermittent lower back pain. Here is my problem. When i am riding, my lower back feels fine. However, after doing like 20 miles i get off and i can barly bend over--i stretch and all--but the next few days my lower back just screams in pain. My lumbar muscles are all tight and i get a stabbign sensation at my waistline.
My question is what can i do to prevent this. Anyoen else have similar problems. I dont understand why my back doesnt hurt when i'm on the bike but hurts when i get off. Also, is this due to an incorrect ridign position---am i too spread out? Any advice/suggestions would be appreciated.
