For non-native English speakers, the word "bouldering" appears rather strange; almost comical. However, what it describes is a fairly ordinary, and for some, serious, activity.

Bouldering is akin to rock climbing, but there are significant differences between the two. In bouldering, the height of the rock is restricted, usually to less than six meters. In rock climbing, which frequently involves ascending heights of over 30 meters, a rope and harness are sensible precautions. In bouldering, they are not required.

In the interests of safety, "boulderers" use climbing shoes to make footholds secure, chalk to provide a firmer grip, and special mats to prevent injury in the event of a fall.

As a sport, bouldering offers a serious workout for women as well as men. The indoor version is especially popular because venues are located within cities. Unlike rock climbing, it can be practiced irrespective of the weather.

The growing popularity of bouldering is explained by a number of factors, chiefly the physical benefits. It can improve upper limb strength, balance, overall flexibility, and a range of motion. Like rock climbing, bouldering requires the use of almost the entire musculature of the body and therefore helps you develop better coordination.

One last plus point, it's a sport that can be done alone. So, anyone wanting to keep fit and alert while maintaining social distancing, should look no further than their local bouldering-equipped gym.
