I feel so out of control when I'm standing. I am watching a lot of "enduro riding tips" videos on YouTube, and I can tell that standing up is CRUCIAL. What are the keys to feeling comfortable standing on the bike? One thing i'm thinking is that I'm not "moving" enough on the bike... These enduro guys look like they're constantly adjusting and shifting and really working their machines... But I just feel like I'm hanging on for dear life -- stiff and afraid to move around ... Seat time is the key I guess .
