Jummaring, also referred to as jugging, is where the second climber (the one who belays the lead climber on the route) uses ascenders to climb the rope instead of climbing directly on the rock.
"Along with the ascenders, one or more webbing "ladders" called étriers (or aiders) "
are typically used to allow the climber to use their feet to step up and pull
themselves up the rope.
Ascending is not typically performed on free climbing routes where a climber uses
his or her hands and feet on the rock, climbing the features, edges, cracks, and pockets that the route provides
without artificial aids.
" Typically, ascending is reserved for aid climbing where the climbers are"
climbing near-featureless faces of rock, usually with very thin cracks that a
person probably could not get their fingers into to make the holds useful .
