TrekHawk, going over an obstacle uphill may involve some throwing of weight around. You have to keep your weight balanced between the two wheels to keep traction at the back but also keep the front wheel down.

When you come to the obstacle you may have to unweight the front wheel a bit to lift it over but just a tad as the suspension will absorb a lot. You may have to apply a power stroke simultaneously. Then you need to get your weight immediately forward to get the wheel back down but again, not too much, because you need to keep traction on the back. Consciously try to keep your upper body low and forward over the bar.

If you have no obstacles but a really steep hill, more forward on the saddle and stick the nose where the sun don't shine. Bend your elbows, pull them back and down. Keep them close to your body. Your nose may be feel like it's on the bars. Smooth, even cadence is critical. This is in the Ned Overend video. Depending on where you carry your weight, you may need to be a little more extreme at this than men who carry more weight in their upper torsos.

I haven't looked at a picture of your bike, but too much rise on your stem can make it hard to keep the front wheel down but make it super easy to lift.

One thing more, I have been ever so much better at technical uphills with the greater power I have built the last year. It can be a series of anerobic bursts so back off on the effort level between roots to get in a bit of recovery.

Boy, all of these is so hard to put into words.

Where're you riding? We need to get coordinated.
