Plogging is a combination of jogging with picking up litter (merging the Swedish verbs plocka upp (pick up) and jogga (jog) gives the new Swedish verb plogga, from which the word plogging derives). It started as an organized activity in Sweden around 2016 and spread to other countries in 2018, following increased concern about plastic pollution. As a workout, it provides variation in body movements by adding bending, squatting and stretching to the main action of running, hiking, or walking. Plogging is considered a perfect activity, as it is positive both for the body, and for the environment. An estimated 2,000,000 people Plog daily in 100 countries and some plogging events have attracted over 3,000,000 participants.
