A company in Chengdu, Sichuan province, has required employees who arrive late to climb the stairs to its 19th floor office.
The measure has been more effective than imposing fines, West China Metropolis Daily reported.
Almost no employees have shown up late since the new measure was introduced a month ago to replace the fine of 100 yuan ($16).
The report said many employees have endorsed the measure as an opportunity to workout.
