Put your feet up 翘起脚来 彻底放松
According to the British Synchronised Swimming website, competitive swimmers must be extremely fit, and completely at home in the water. When tested and compared with other Olympic athletes the results showed that synchronised swimmers ranked second only to long-distance runners in aerobic capacity.
短语 to put your feet up 的意思是“休息放松”。它也尤其被用来形象的描述在辛苦工作一天后坐在沙发上“把脚翘起来，彻底放松”的样子。
I like nothing better than putting my feet up after a hard day at work!
You work so hard. Come on, sit here and put your feet up!
短语 to find your feet 的意思是“适应新环境”。
I'm new in the company. I need time to find my feet.
