Anyone have any simple routines they can share? Mainly to stay flexible. My gait seems to be shortening with all the long, slow mileage i've been doing, i'm also feeling very tight in the hamstrings even though I do dynamic stretching after each run. I'm interested in whole body exercises, but there seems to be sooo much information out there it's hard to know where the good routines start and where the charlatans end, if you get my meaning. A little point in the right direction would be most welcome. Thanks.
