A skipping rope or jump rope is a tool used in the sport of skipping/jump rope where one or more participants jump over a rope swung so that it passes under their feet and over their heads. There are multiple subsets of skipping/jump rope, including single freestyle, single speed, pairs, three-person speed (Double Dutch), and three-person freestyle (Double Dutch freestyle).

Rope skipping is commonly performed as an exercise or recreational activity, and there are also several major organizations that support jump rope as a competitive sport. Often separated by sex and age, events include hundreds of competitive teams all around the world. In the US, schools rarely have jump rope teams, and few states have sanctioned official events at the elementary school level. In freestyle events, jumpers use a variety of basic and advanced techniques in a routine of one minute, which is judged by a head judge, content judges, and performance judges. In speed events, a jumper alternates their feet with the rope going around the jumper every time one of their feet hits the ground for 30 seconds, one minute, or three minutes. The jumper is judged on the number of times the right foot touches the ground in those times.
How to skip rope?
A skipping rope is a fun form of exercise that is enjoyed by children and adults. 
While holding on to both ends of the rope, allow the middle of rope to rest on the ground in front of your feet, step over the rope so the rope is now behind your feet. 
Simultaneously, swing both arms over your head in a full swing so the rope is follows the motion of your arms and just before the rope reached the front of your feet, hop with both feet, avoiding the rope and continue the rhythm repeatedly.
