Although I consider myself to be a cross-country mountain biker it is always good to think cross-functionally in nature and keep up with other mountain bike disciplines. To that end, I sometimes pick up Decline Magazine, which is focused on Downhilling and Freeride.
Decline - in partnership with Fluidride - has a couple of nice technique videos on their website that could prove helpful to any rider looking to push themselves beyond their current limits. Of particular note is the video showing the many techniques to flow off of drops. More advanced riders might also want to take a look at ways to improve their jumping skills.
Shyyyt...I'm still working on my log hopping...next up...wall rides!!!
