Pro athletes pretty much all do stretching even if it's formally 'yoga'. I've seen NFL players warm up, they even have guys to help them do the leg stretches, heh. A long time ago ace Aussie cyclist Ian Jackson wrote a book on yoga for athletes--back then yoga was not so well-known in US etc. He wrote that yoga did much to help minimize or prevent injuries. I once read an article by an exercise expert that noted while many racers do a fairly good job at leg stretches, they often neglect other stretches esp back/hip etc. & a lot of times, until one starts doing yoga, one isn't aware of how tight certain parts really are.

Ideally, one should do cardio, stretching & strength training. I guess we bikers want to hop on the bike & get some miles in, it's easy to neglect stretching/strength parts, I'm certainly guilty there. Well ski season is coming up, yoga is also highly recommended for skiing too.
