Finding time to commit to exercise can be a real challenge, forcing many of us to squeeze in a quick run or gym session whenever there's a spare moment. It might be time to rethink those habits.

　　找时间运动可真是一项挑战，这强迫我们中的许多人去挤时间出来快速跑跑步，或者做个操，无论何时有空闲时间。也许这正是重新思考一下这些习惯的时候了。

　　New evidence suggests if you really want to make the most of your exercise, you should do it at the same time each day. It's a schedule your body will thank you for.

　　新的证据显示，如果你真的想让锻炼起到最好的作用，那么应该在每天同一时间进行锻炼。你的身体会感谢这个时间表的。

　　A study lead by researchers from Brown Alpert Medical School in the US has shown it really doesn't matter if you're a dawn jogger or a twilight cyclist; it's the consistency that's key if it's weight-loss you're after.

　　美国布朗阿尔伯特医学院的研究人员的一项研究表明，无论你是晨跑还是夜骑，其实都没那么重要，坚持才是你所追求的减肥的关键。

　　The US Department of Health and Human Services suggests two and a half hours of moderate physical activity each week is the least we should be doing to keep healthy.

　　美国健康和人类服务部表示，我们每周最少应该进行2.5小时的适度身体活动，以便保持健康。

　　And not just a minute here or there, but at least 10 minutes of heart-pounding exercise in each session.

　　也不是这里锻炼一分钟，那里锻炼一分钟，而是每组最少10分钟的让人心跳加速的锻炼。

　　Needless to say, if you're fairly fit and in a good state of health, you're probably meeting this requirement. But many of those who have problems keeping their weight down often struggle to get the exercise they need.

　　如果你身体状况很好，很健康的话，无需多言，你已经达到了要求。但是那些无法减轻体重的人通常很难得到他们需要的锻炼。

　　Using survey results on the physical activity of 375 individuals exercising for weight loss, the researchers identified a strong relationship between a moderate-to-vigorous level of exercise at the same time of day and the amount of time spent exercising.

　　研究人员利用对375名个体为了减轻体重进行的身体活动的调查结果，发现了每天在同一时间的适度至活跃水平的运动与进行锻炼的时间有着很强的关联。

　　Roughly half of the volunteers were morning people, which, when taken in context with a previous study by some of the same scientists, could indicate physical activity before you start your day is the way to go.

　　大约一半志愿者是早上做运动，若是将这点与之前同一批科学家做的研究联系起来，可以发现在一天开始之前进行身体活动是正确的。

　　This preference for regularity might all come down to the way we think about our diary.

　　对于规律性的偏爱可归结为我们对日程簿的看法。

　　Activities we expect to do at set times – such as picking up the kids, going to work, or attending social meetings – aren't really things we give a great deal of conscious thought to.

　　我们在特定时间进行的活动--比如接小孩、去上班、参加联欢会--这些事我们通常都不会很有意识地考虑。

　　This mindless repetition is referred to as automaticity in psychology circles, and has already been shown to be important when it comes to sticking to an exercise regime.

　　无意识的重复在心理学圈子里被称作自动性。当谈及坚持锻炼规则的时候，自动性很重要。
