Sit-stand systems (also known as frog rig) - one ascender is at chest level attached to the sit harness, and a second is held in the hand with a long loop of rope for the feet. Movement up the rope is by repeated moving of the foot loop ascender up the rope, pushing up with both feet together, and sitting, supported by the chest ascender.
An ascender is a device (usually mechanical) used for directly ascending, or for facilitating protection, with a fixed rope when climbing on steep mountain terrain. A form introduced in the 1950s became so popular it began the term "Jumar" for the device, and the verb "to jumar" to describe its use in ascending.
The ascender will glide smoothly up the rope when the belayer takes in slack. If the climber falls, the ascender will lock up. (I’m giving them the benefit of the doubt and assuming that the ...
