“节约时间”
用英语怎么说？

When asked why he exercises in denim, Kennedy says it is a matter of saving time. He goes hiking first, then goes straight to the gym, so he does not want to change clothes. However, fitness historians believe this habit comes from the workout culture of his youth. In the 1980s, strong powerlifters and famous bodybuilders often wore jeans during photoshoots to look tough. Kennedy, who is now 72, might simply be a living fossil of that era. Interestingly, a younger generation is now bringing back this style. Influencers run marathons in jeans, and some clothing brands sell special stretchy pants that look like denim. This playful trend shows how fashion in fitness can quickly change. What starts as a joke today often becomes a popular style tomorrow.

当被问及为什么穿着牛仔裤锻炼时，肯尼迪说这是为了节约时间。他先去徒步，然后直接去健身房，所以他不想换衣服。然而，健身历史学家认为，这种习惯源于他年轻时的健身文化。在20世纪80年代，强壮的举重运动员和著名的健美运动员经常在拍照时穿着牛仔裤，以显得强悍。现年72岁的肯尼迪可能只是那个时代的活化石。有趣的是，年轻一代现在正在带回这种风格。网红穿着牛仔裤跑马拉松，一些服装品牌也销售外观像牛仔裤的特制弹力裤。这种好玩趋势表明，健身时尚可以快速改变。今天以玩笑开始的事情，明天往往会成为一种流行的风格。
