5 . Rock climbing might seem extremely dangerous, but most climbers know what they’re doing. Over the years, climbers know what they’re doing. Over the years, climbers have developed knowledge and techniques that allow them to conquer rocks safely. There are different kinds of rock climbing and it’s mainly based on the equipment used. The two main categories are aid climbing and free climbing. Aid climbing uses equipment, such as screws inserted into rocks to help climbers pull themselves to the top. In free climbing, most climbers use equipment only to protect themselves from falling: they don’t use any tool to help them climb up the rock. In free climbing, it’s all about skill, strength and knowledge.
You might think that muscles are the most important factors in this extreme sport. Not so, says Jeremy Noris, a rock climber in US. “ Your can’t muscle your way through climbing no matter how hard you try”, he says. More important factors are balance, coordination, and the ability to make your body tense, which helps climbers pull themselves up. Norin also says that lower-body strength in actually more important than upper-body strength. One of the best climbers Norin knows can only do seven pull-ups, but he has no problems climbing up some of the most rugged rock faces around.
Although some climbers have mastered the sport, beginners are welcome. Start with bouldering, a kind of climbing without a rope that take place on a rock three to five meters tall, so that falling won’t result in serious injury. Believe me- it won’t seem that low when you are looking down from the top.
