使了渾身解數 的英文怎麼說?

[1] to fall all over oneself to do something[2] to try very hard to do something[3]  to bend over backwards to do something[4] to pull out all the stops

使出渾身解數做某事 = to fall all over oneself to do something = to bend over backwards to do something

當然，你也能只用 to try very hard to do something 就夠了。

另外，to pull out all the stops = 為了達到某個目標而使出所有的方法，也就是竭盡所能全力以赴，例如例句的律師為了贏得勝利會全力以赴
