To build up endurance and strength, they do "human weight-lifting" in pairs. One person lies on the floor and the other puts his hands and feet on those of the first. The one on the floor then pushes his partner up into the air. Or they do sit-ups in groups of three, heels interlocked--one set is 100 sit-ups.
為了培養耐力與體力，兩人一組做「人體舉重」，一人仰躺，與另一人手腳相反連結，然後慢慢將伙伴撐起來；或者 3 個人腳跟交疊做仰臥起坐，一做就是 100 下。
