There is a saying that never too old to learn and, similarly, I want to say that never too old to do exercises. Doing exercises is really necessary for everyone and we’d better take some time to do exercises every day.

有一句话是这样说的，活到老学到老，同样的，我想说活到老锻炼到老。锻炼对每个人来说都是很有必要的，而且我们最好每天都花点时间来锻炼。
General speaking, doing exercises appropriately every day is definitely good for our health. For one thing, doing exercises properly is a good way to building our body and accelerate our blood circulation. For example, to do sit-up every day can practice our waist. For another, doing exercises is also a good method to keep our mind healthy because doing exercises can broaden our mind and release our stress to a large extent. For example, we would feel better if we do some exercises after working for a long time. 
一般来说，每天适当的锻炼肯定是有益于我们的健康的。一方面，适当的锻炼是塑造强壮的身体以及加速血液循环的好方法。例如，每天做仰卧起坐可以锻炼我们的腰。另一方面，锻炼也是保持头脑健康的一种好方法，因为锻炼在很大程度上可以开阔我们的眼界、释放我们的压力。例如，长时间工作后做一些锻炼可以让我们感觉更好。
In addition, doing exercises can make our mind be more active. That is why so many people choose to do exercises when they cannot come up with new ideas. 
此外，锻炼可以让我们的思维更加活跃。这就是为什么那么多的人在想不出新法子的时候会去做运动的原因。
All in all, doing exercises is absolute necessary. If you say that you are too busy to run, to take some deep breath or expand your chest every day would be better than do nothing.
总之，锻炼是绝对有必要的。如果你说你太忙而没时间去跑步，每天做一下深呼吸或扩胸运动都会比什么都不做好。
