天气预报说没有雨的话，我们就可以到外面的阳光下(当然要涂些防晒霜)来尝试这些娱乐活动，能出门的时候就花少一些时间在室内健身室里喽。

　　Playing Tennis: Burn Factor = 445 calories

　　打网球：燃烧值=445卡

　　It doesn’t take very long on the court to break a sweat. Turns out, that’s thanks to the massive amount of calories you’ll burn perfecting that backhand.

　　在球场上，不消多久你就会流汗。事实证明，熟练的反手击球会帮你燃烧掉大量的卡路里。

　　Biking for Fun: Burn Factor = 509 calories

　　骑单车消遣：燃烧值=509卡

　　That’s right, biking at just a moderate speed burns around 500 calories in an hour. I’ve started riding my bike to work every day—incorporating activity naturally without it really feeling like “exercise time.” Work too far from home to ride there? Just bike to the store when you can, or for fun around your neighborhood.

　　没错，速度适中地骑单车能够在一小时内燃烧大约500卡路里热量。我每天开始骑车上班，把活动自然地合并，让它看起来不像是“锻炼时间”。上班的地方离家里太远，不能骑过去?那就在去商店的时候骑车过去喽，或者在附近骑车消遣也可以。

　　Rollerblading: Burn Factor = 764 calories

　　轮滑溜冰：燃烧值=764卡

　　It’s a little cheesy, sure, but for 700-plus calories per hour, what more creative way to get from place to place when the sun is shining than Rollerblading—especially if you’re somewhere with a nice bike path.

　　这个运动稍微有点俗气，当然了，冲着一小时燃烧700+的卡路里的份儿上，在如此烈日炎炎之下，又有什么更加有创意的方式能让你从一处很快到另一处呢---特别是如果你在一处有很好自行车道的地方。

　　Dancing: Burn Factor = 414 calories

　　跳舞：燃烧值=414卡

　　Spending a steamy summer night learning salsa or grooving to some live music? Yes, please. Calories or no calories, jamming alfresco screams summer for all the senses.

　　是说学跳萨尔萨舞曲或是在现场音乐中起舞来度过潮湿的夏季夜晚吗?对，就是这样。不管能不能消耗卡路里，先让所有感官被户外热热闹闹的夏季填满吧。
