The centre of gravity is very important in relation to stability. If a line through the centre of gravity falls within the structures base then it will remain stable.
The Critical Point is reached when the Center of Gravity is no longer above the base of support.
Stances are not fixed positions that are held when you are free fighting.
Comparing C.G biking posture with C.G karate posture
This is the common wrong posture most new cyclists will make. Apparently the person and bicycle are fixed to a triangle which is known to all that is the most stable frame. Then neck pain and shoulder pain will follow you for several days.
The right posture of biking is like below. You should contract your abdomen. And your body should form an unstable quadrangle with the bicycle so that you can adjust your center of gravity easily to respond to the unexpected change of road condition. The hands are just used for assist, you need not handle or push the handle bar hardly with your hands. So you´ll never have neck pain and shoulder pain after cycling.
Then let´s talk about upslope. If we do not change our usual riding habit, we can hardly ride our mountain bicycle to the slop. Remember to shift your center of gravity.
The right posture of upslope is based on right riding posture. You should sit your ass at the front point of the saddle, and bend down your arms to shift your center of gravity to the front.
When you are going downslope, you need to shift your CG (center of gravity) to the back and you´d better move your butt to the end of the saddle.
