????步入隨時健身俱樂部（Anytime Fitness），你可能會注意到，這里缺乏普通健身房的許多特色。沒有大型健身器械，沒有擁擠的人群，也沒有喘著粗氣的健身愛好者彼此較勁。

????你還會注意到，這家健身俱樂部的面積很小——只有4000到6000平方英尺，比起Equinox等提供全方位服務的健身中心，它的面積小了將近八倍。健身房里干凈整齊，沒有員工把文件推到你面前，勸說你報名參加健身房最新的減肥計劃，“五天狂減20公斤。”

????在這個輕松友好的環境中，我們看不到這些景象，正如隨時健身俱樂部首席執行官查克?魯尼恩希望的那樣：“我們就像不賣啤酒的歡樂酒吧。”

????當然，在電視劇《歡樂酒吧》（Cheers）里，人人都知道你的名字。但是這個地方沒有電視劇主角薩姆和戴安娜的愛恨情仇，也沒有總是垂頭喪氣的諾姆和克里夫。

????根據國際健身球類和體育俱樂部協會（The International Health Racquet and Sportsclub Association,）今年發布的報告顯示，正是這種良好的氛圍幫助隨時健身公司成為世界增長最快的健身俱樂部，這也是這家家公司連續六年保持的一項項殊榮。過去11年里，這家總部位于明尼阿波利斯的連鎖企業擴展到全球2,200多家健身俱樂部，遍及美國50個州和14個國家。相比之下，賽百味（Subway）用了23年時間才開設了2000家餐廳，而麥當勞（McDonald）用了32年時間才達到2000家餐廳。

????盡管隨時健身俱樂部缺乏普通健身房的傳統特色，但是卻擁有種類繁多的健身課程。走進俱樂部，你會發現前臺有100多種不同的視頻課程供你選擇，可以隨時報名參加。你想鍛煉肌肉嗎？盡管來吧。你想學習搏擊健身操嗎？他們也有這個項目。挑選自己想參加的課程，走進多功能廳，然后就可以開始認真鍛煉了。如果這些課程不能提起你的興趣，隨時健身俱樂部還配備有氧健身器械，比如跑步機和橢圓機，以及阻力訓練設備和舉重器材。

????有些熱情的會員和員工會秀出隨時健身俱樂部的紋身，驗證了這家健身房和會員的特殊關系。魯尼恩說：“在2005年的一次會議上，有位圣路易斯的特許經營者開始這么做。從此以后，有1,000多人紋上了隨時健身俱樂部的紫色跑步男子紋身。”

????他當然了如指掌，因為為紋身買單的就是隨時健身俱樂部。所有紋身者要做的只是告訴大家，他們為什么要紋這個圖案。每個人的理由各不相同，有些人歸功于這家健身俱樂部讓他們的體重明顯下降，或者提升了他們的自尊心。

????可以肯定的是，隨時健身俱樂部的迅速崛起恰逢健身俱樂部行業整體的繁榮發展。根據市場研究公司IBISWorld的研究顯示，全美國健身俱樂部會員有望在2013年達到5,200萬人，創下歷史新高。2013年美國健身房、健身會館和健身俱樂部的營收預計高達259億美元。隨時健身俱樂部的營收在過去五年增長了80%，到2012年年底超過4.84億美元。魯尼恩預計整體營收將在今年年底超過6億美元。

????Step inside an Anytime Fitness gym and you'll likely notice more of what it lacks than what is there. No massive machinery, mobs of people, or grunting bodybuilders trying to outdo one another.

????You'll also take note of the club's particularly small size -- only 4,000-6,000 square feet, nearly eight times smaller than full-service gyms like Equinox. It's clean and tidy, and there are no employees shoving papers in your face convincing you to sign up for the gym's new weight loss plan, "how to lose 50 pounds in five days."

????There is none of that in this decidedly unintimidating environment, and that's exactly how Anytime Fitness CEO Chuck Runyon wants it. "We are Cheers without the beers."

????Cheers, of course, the place where everybody knows your name. But this spot doesn't have any Sam-and-Diane-relationship-tensions, and Norm or Cliff won't be dropping by anytime soon.

????It's that vibe that has helped make Anytime Fitness the fastest growing fitness club in the world, according to a report released this year by The International Health Racquet and Sportsclub Association, a title the company has held for the last six years. In 11 years, the Minneapolis-based chain has expanded to more than 2,200 clubs worldwide, in all 50 U.S. states and 14 countries. By comparison, it took Subway 23 years to reach 2,000 restaurants and McDonald's (MCD) 32 years to reach 2,000 restaurants.

????Anytime lacks some of the traditional trappings of a gym, but it does have plenty of classes. Walk in, and you will find a kiosk holding more than 100 different video classes that are accessible at all times. Want muscle conditioning? Got it. Want to take a turbo kicking class? They have that too. You pick your class, head into a multi-purpose room, and you're off and running. If the classes don't intrigue you, Anytime Fitness has cardio equipment like treadmills and ellipticals along with resistance workout equipment and free weights.

????The relationship between the gym and its members is special, as evidenced by the Anytime Fitness tattoos sported by its passionate members and employees. "It started with a St. Paul franchise owner at a conference in 2005. Since then, over 1,000 people have gotten the Anytime Fitness purple running man tattoo," Runyon said.

????He should know. Anytime Fitness foots the bill for the body art; all the tattoo recipients have to do is share why they're getting it. The reasons vary, including some crediting the chain with dramatic weight loss or boosting their self-esteem.

????To be sure, Anytime Fitness' ascendance coincides with a boom in the fitness club industry as a whole, with membership expected to reach an all-time high of 52 million in 2013, according to research from IBISWorld. Revenues for gym, health, and fitness clubs in 2013 are estimated to reach a record high of $25.9 billion. Anytime Fitness has seen revenues grow by 80% in the last five years to more than $484 million at the end of 2012, and Runyon anticipates system-wide revenue exceeding $600 million at the end of this year.
