"流行的運動迷思大解密"

當我們提到運動和健身時，我們幾乎每個人都至少知道一位自稱是專家的人。儘管這些人可以給我們一些離開沙發並且開始運動的動機，但是他們提供的建議未必總是有用，有些甚至是老掉牙的迷思。

其中一個最流行的運動觀念就是舉重對減肥而言並不是特別有效。雖然在舉重的時候確實不會消耗太多卡路里，但是當你結束重訓之後，你的身體仍會繼續消耗熱量。由於肌肉量的增加會引起更快的靜止型新陳代謝，因此當你的肌肉變大之後，就算你什麼都不做，你還是會消耗卡路里。

今日許多人會告訴你跑步對膝蓋有害，但是卻沒有太多證明可以支持這個觀念。事實上，研究顯示只要你做好暖身運動並且穿上合適的慢跑鞋，跑步可以強化你的關節。最後如果你想要加強鬆弛的肌肉，那麼請舉重的啞鈴，而非輕的啞鈴。如果你想讓肌肉更加結實，你就必須比平常更努力舉重了。

(Health) Debunking Some Popular Exercise Myths

When it comes to exercise and getting fit, nearly all of us know at least one self-professed expert. While these people might give us the motivation we need to get off the sofa and do something physical, the advice they hand out is not always as useful, and some of it is just oft-repeated myth.

One of the most popular exercise beliefs out there is that weight training is not particularly effective when it comes to losing weight. Although it is true that a session of weightlifting will not burn off many calories, your body will continue to consume energy long after youve finished training. And since an increased muscle mass will result in a higher resting metabolism, when your muscles are bigger, youll burn calories even when youre not doing anything at all.

A lot of people will tell you nowadays that running is bad for your knees, but theres very little evidence to support that belief. In fact, studies have shown that as long as you warm up properly and wear the right footwear, running can strengthen your joints. And finally, if you want to tone up loose muscle, lift heavy weights, not light ones. To make a muscle tighter, youve got to push it harder than you normally do.
