Stretching and resting
Since I turned 30, I found that if I don't stretch before using my bicycle, I get horrible cramps the next day.
I know, they taught me in school that I needed to stretch before doing any exercise, but it seemed unnecessary when I was a kid or even a teenager just to hop on my bike and go somewhere.
One thing I've never been clear on is a good rule of thumb of how long after I stop riding before I need to stretch again.
For example, let's say that I ride the bike to Wal-Mart, then spend 20 minutes locating what item I need and then waiting in line to check out.
Would I need to stretch again? I'm just wondering what should be the cutoff point. I've been using about 10 minutes, because I really don't want those cramps the next day.
