If you are a newbie, you should only climb with an experienced partner, which will belay you with the rope from above. But there may be a situation, when you have no choice but to stand in front of a rock wall. Before you start climbing, take a close look at the rock carving, trying to choose the easiest way. Also, while already in the wall, constantly look around for the best holds and places, in which the rock is well carved. If you have doubts whether you have chosen the right option, back off before you get stuck in the rock.

Entering

Plan the best system of movements in sight, and be prepared to traverse, when the road straight up turns out to be impassable. Use your leg muscles first and foremost, Only use your hands to keep your balance.
Try to choose not too low grips, to keep the balance better.
Climb smoothly and decisively, so as not to lose balance.
Take your weight with ease, do not stand in an uncomfortable position for too long, go back to the previous steps, if you don't find convenient holds or steps above

Descent

Descending steep terrain is usually more dangerous. The gentle slope can be descended from the front, but when the steepness rises, you have to turn around and start climbing, only down. Grips and steps are then harder to find, which you cannot see under your feet. While going down you have to look at the rock below us and plan the next few moves.
Always look for holds and steps above the head and to the side, to be able to use them in the absence of a suitable support below.
Go down slowly and carefully to the chosen steps. It may be, that they cannot support you, so you must always be able to, retreat to the top.
Once you've found the step, don't step on your fingertips, keep your heel low.
