My right lower back gets sore on any type of hill and sometimes on the flats if I'm pushing a high gear. After doing some research it looks like it may be related to weak or inflexible hamstrings. This makes sense as my right leg is weaker and less flexible than my dominant left leg. The question is: What should I do about it? Should I just spend alot of time streching the right leg or do I need to strengthen it? I don't have weights and I don't want to join a health club right now. Are there any exercises I can do? Any links to good web sites?
Thanks in Advance
