     If you have ever been rock climbing, you will know that it is not a very easy sport. In fact, you probably felt quite defeated when you first tried to do any serious climbing. Indoor and outdoor rock climbing are

both extremely demanding and require practice to get good at. It is one of the most physically and mentally demanding sports.

     There are three basic types of rock climbing. Top roping is the most common type and the climber

need to climb with a partner. The second type, which is very similar to top roping, is called lead climbing.

In both of the types, the climber can sit off the wall and rest on the rope. The third type is called

bouldering. Bouldering is a type of free climbing without any ropes. This is the most demanding of all

climbing types. The climber must be able to complete the climbing without taking a rest on the rope.

     Believe it or not, climbing is said to be about 75% legs and only 25% arms. To climb efficiently and

successfully, a person needs to have a wonderful technique. One of the major rules of rock climbing is to

always have three points touching the wall, whether it is both feet and one hand, or one foot and both

hands, as it is much easier to have your weight rest on three points than on two. Another important idea to grasp is that your arms in most cases will do the climbing; they only hold you into the wall so that your

legs are actually pushing you upward. Also, the closer you are to the wall, the easier it is to climb.

     Rock climbing may sound a bit too extreme for the everyday person, but it is really an amazing

workout. Once you get into the sport, and learn how to position your body and rest your weight, then you can begin to deal with some difficult problems. The great thing about rock climbing is that it is mentally

challenging as well. You are constantly analyzing the way your body moves and how to do certain moves

on the wall. For anyone who wants to get into shape, rock climbing is a fun and effective way to exercise muscles.
