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.

找時間運動可真是一項挑戰，這強迫我們中的許多人去擠時間出來快速跑跑步，或者做個操，無論何時有空閑時間。也許這正是重新思考一下這些習慣的時候了。

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.

新的證據顯示，如果你真的想讓鍛煉起到最好的作用，那么應該在每天同一時間進行鍛煉。你的身體會感謝這個時間表的。

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.

美國布朗阿爾伯特醫學院的研究人員的一項研究表明，無論你是晨跑還是夜騎，其實都沒那么重要，堅持才是你所追求的減肥的關鍵。

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.

美國健康和人類服務部表示，我們每周最少應該進行2.5小時的適度身體活動，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.

也不是這里鍛煉一分鐘，那里鍛煉一分鐘，而是每組最少10分鐘的讓人心跳加速的鍛煉。

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.

如果你身體狀況很好，很健康的話，無需多言，你已經達到了要求。但是那些無法減輕體重的人通常很難得到他們需要的鍛煉。

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.

研究人員利用對375名個體為了減輕體重進行的身體活動的調查結果，發現了每天在同一時間的適度至活躍水平的運動與進行鍛煉的時間有著很強的關聯。

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.

大約一半志愿者是早上做運動，若是將這點與之前同一批科學家做的研究聯系起來，可以發現在一天開始之前進行身體活動是正確的。

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

對于規律性的偏愛可歸結為我們對日程簿的看法。

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.

我們在特定時間進行的活動--比如接小孩、去上班、參加聯歡會--這些事我們通常都不會很有意識地考慮。

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.

無意識的重復在心理學圈子里被稱作自動性。當談及堅持鍛煉規則的時候，自動性很重要。
