只工作不玩耍，聪明孩子也变傻（All work and no play makes Jack a dull boy），可想而知，娱乐休息的重要性。同样，要养精蓄锐，必须得让自己得到休息，可以好好睡一觉，也可以度个假轻松轻松。
养精蓄锐用地道的英语表达是 recharge one's batteries，不要把它理解为”充某人的电池“。充电的正确表达方式是 charge sth up 或 recharge sth，其中 recharge 是从 charge 衍生过来的，意为”充电“时，它们有些许区别，大体上可以通用，例如：She left the phone charging overnight.She drove the car round the block to charge up its batteries.The drill takes about three hours to recharge.We use solar panels to recharge the battery.
因此用 recharge one's batteries 来形容养精蓄锐或休整非常地贴切，最终的结果是达到精力旺盛的结果；这通常是通过take a long break，rest 或 relax 等来实现的，例如：After all of this hard work, set some time aside to recharge your batteries.在所有这些艰苦的工作之后，留出一些时间让自己好好休息一下。My mother came home at 3 am after a 6-hour long flight, and that is why she slept till 2 pm to recharge her batteries.经过6个小时的长途飞行，我妈妈凌晨3点就回家了，这就是她为什么要睡到下午2点才能休整过来的原因。It's amazing how a short walk in the woods can really help you recharge your batteries sometimes.在树林里散步有时真的能让你养精蓄锐，真是太神奇了。Companies need to remember that vacations are crucial for employees to be able to recharge their batteries so that they can maintain their productivity.公司需要记住，假期对员工来说是至关重要的，这样他们才能养精蓄锐，从而保持生产力。
Recharge one's batteries 后的结果是使人精力旺盛或充满活力，可以用习语 vim and vigor (vigour) 来表示，例如：
Show more vim and vigor! Let us know you’re alive.
展现更多活力！让我们知道你还活着。
If you wish to reduce your weight, then exercise daily with all your vim and vigor.如果你想减轻你的体重，那么每天都要精力充沛地锻炼。
其实 recharge 本身就有”恢复体力，恢复精力，休整“的意思，但衍生的形容词是 rechargeable 没有类似的意思，例如：It's important to have regular breaks and to take time to recharge.rechargeable 意为”可充电的“，常与 battery 连用，例如：We try to buy reusable, repairable, and rechargeable products.Some recent accelerographs employ a lead dioxide rechargeable battery.理想需要的是可”充电“的躯壳，因此累的时候，请好好休息一下，保养好自己的身体。
