Gymnastics wall bars (also known as a gymnastics ladder or stall bars) were invented at the beginning of the 19th century by the Swedish teacher Per Henrik Ling who, when suffering from arthritis, realized the therapeutic potential of wall-bars exercise.
With the support of the Swedish king, Ling founded The Royal Institute for Gymnastics, where he taught gymnastics as an art, which later became the working system in whole Europe. He later invented the vaulting box.
With the arrival of emigrants in America, the wall bars were quickly adopted in the USA.
Gymnastics wall bars are a multifunction device, made of lamellar and beech timber. They can be manufactured in different sizes, from the recovery, for children up to the double, which may have a size of 2.50 x1, 70 m. The parallel bars are made of beech or maple wood and commonly number 7, 14, or 16 pieces.
The top bar is extended further than the other bars to facilitate exercises where the user hangs vertically. The bars are 40 mm thick and oval shape. An incline board or pull-up bar can be attached to the bars.
The wall bars have many uses and are widely used in gyms and schools. They are used simply for climbing and for coordination skills, particularly in primary school education. They are also used by more advanced gymnasts for resistance training, flexibility training or abdominal exercises. Gymnasts can hang from a higher bar with their back facing the bar and perform abdominal exercises, or hang facing the bar to stretch their back. Wall bars are also useful for parkour training. They provide several different heights to jump to and provide an area to jump off from.
