Unfortunately there's no shortcut; you have to put the time in the bumps to feel comfortable in them. If you're defensive in the bumps ( as you've said ^ ), then you're fighting them and you are going to tire yourself out. You have it much easier in the west than we do here in the east; true icy bumps can be a bitch to learn on. Go play in a soft mogul field and keep skiing it over and over. Start traversing through the field and work on flex and extending, edging and slipping skills. Two, three turns on each bump, ski every part of every bump. Take your time. Keep yourself in an athletic stance and Play with speed control. Keep traversing and slowly add less traverse and more fall line. Find where your weakness is and work on that. Ski alone once in a while and just play in the bumps all day. Ski them as slowly as you can sometimes and then as fast as you dare. Ski a few bumps in a line and then stop, take stock and repeat. Stay relaxed and if something hurts, don't do that, there are plenty of techniques, try something different. There are lots of drills you can do outside of the bumps and a lot of them have been posted at pugski in various bump threads. Practice quick short turns ( tick toc turns - 2 turns per second ). Practice short turns in a flexed stance, a tall stance. etc... Hit every skier made pile of snow on the groomed runs.
