My chiro suggested this series of yoga poses, from a company called brushymountain publishing.com. They have yoga series for many sports, but my recommended one was for paddlers. Its two sets of 22 minute yoga in a downloadable format, and inexpensive. I do them both when I have time, or just one a day. Either day, its really helped my core, flexibility, and strength. What I liked about this particular series is they hold the stretches for some time. I am not a fan of flow yoga - flow is too short to gain flexibility.
I will say one thing about all yoga tapes. I wish they (and pilates too) would teach you to use your spine from a neutral position ie no arch and not a flat back. Ok 2 things. I would never do a double leg lift as an exercise, its not a strength building exercise its a test for your back/hip flexor strength. Whenever I heard someone say put your back flattened on the mat, I cringe. We taught that in aerobic classes 25 years ago and now my back is funny shaped - but I digress.
Anyway, just some thoughts. I like the yoga for paddling series. I tried the climbing one, as I used to rock climb, but found it too hard!
