Hi all. My commute is 7.5 fairly leisurely miles. I never ride fast enough to huff and puff, and generally take my ride pretty easy. I've been doing this 5 days per week for about the past 2 years.

I've never been a very nimble or flexible person, always because of tight leg muscles and tendons. In recent weeks though, the stiffness I feel in my legs when stretching has become almost painful. I can't come close to touching my toes, and am lucky if I can reach the top of my shoes without groaning in pain. I feel almost all of this tightness in my hamstrings.

First of all, is this a pretty universal experience? Secondly, what can I do to address this tightness? I am totally open to yoga, so if anyone knows of any routines or stretches specifically targeting these areas, I'm all ears. Is there anything I can change in my diet, keeping in mind that I do not eat meat? Is this something that could arise from poor bike fit?

Any perspective here would be helpful. Thank you!
