Its the original all-girl full-contact sport， high speed and hard core. Skaters like Janis Choplin， Gori Spelling and Skeev Jobs are whipping around a track at lightning speed. But you dont need a name like Broadzilla or Suzy Snakeyes to join the party. In fact， for people who are starting to feel a little bored at the gym， this might be the ultimate full-body workout.

1）Derby-inspired fitness classes are popping up now all over the country， incorporating all the 2）cardio， 3）squats and core training of real roller derby but without the body 4）slams. And the women say its addictive.

Woman 1： Its the only exercise Ive ever been excited about.

At Derby Light in Chicago， women of all ages lace up， and for an hour at least， transform into roller derby 5）powerhouses， and theyre seeing results.

Woman 2： I lost 80 pounds.

While not as brutal as the original sport， it still looks dangerous to me.

Rebecca Ninburg （a.k.a.Demolicious）： Some new girls would come in and theyre like， “Am I gonna get hurt？” and I just tell them 100%...yes.

Cameron Mathison： But they keep comin back.

Demolicious： Because， honestly， the payoff， like you dont feel the pain.

“Demolicious” was a pro herself， but here in Los Angeles at the L.A. Derby Dolls， she offers a derby fitness program for beginners…like me.

這原本是一項(xiàng)全女性參與的高強(qiáng)度運(yùn)動(dòng)，肢體接觸，高速度，硬橋硬馬。詹尼斯·肖普林，戈麗·斯佩林和斯奇孚·喬布斯那樣的輪滑手，正以閃電般的速度繞著賽道滑行。你不需要非得擁有像“巨大無敵”或是“蛇眼蘇茜”那樣的名字才能加入滑輪隊(duì)。事實(shí)上，對于那些對健身房運(yùn)動(dòng)開始感覺厭煩的人們來說，這項(xiàng)運(yùn)動(dòng)可以說是能讓你全身都鍛煉到的終極運(yùn)動(dòng)。

這種受輪滑公開賽引領(lǐng)的健身訓(xùn)練班在全國各地如雨后春筍般涌現(xiàn)，訓(xùn)練包含有氧運(yùn)動(dòng)、蹲伏訓(xùn)練，以及除了身體撞擊外速度輪滑需要的核心訓(xùn)練項(xiàng)目。女士們反映，這是項(xiàng)讓人上癮的運(yùn)動(dòng)。

女士1：我從來沒有如此喜歡一項(xiàng)運(yùn)動(dòng)。

在芝加哥的“輪滑之光”訓(xùn)練場，無論老少，所有女人都做好準(zhǔn)備，至少在一小時(shí)內(nèi)，變身為輪滑能量體，而且她們收獲不少。

女士2：我瘦了80磅（約為72斤）。

盡管沒有真正比賽時(shí)那么暴力，但是對我來說還是挺危險(xiǎn)的。

麗貝卡·寧博格（稱號“無敵破壞王”）：一些新加入的女孩會(huì)問，“我會(huì)不會(huì)受傷呢？”，然后我說，百分之百會(huì)……會(huì)的。

卡梅倫·馬西森：但她們還是會(huì)再來。

“無敵破壞王”：老實(shí)說，那是因?yàn)榛貓?bào)豐厚，讓你好像感受不到疼痛一樣。

“無敵破壞王”本身就是一名專業(yè)輪滑選手，她在洛杉磯開了一家“洛杉磯輪滑甜心”健身室，專門提供針對像我這樣的初學(xué)者推出的訓(xùn)練項(xiàng)目。

Demolicious： Because youre roller skating， youre moving fast， its really exciting， your 6）endorphins are going. Its almost like fitness is a by-product cause the game is so awesome.

Jess Beatty has been taking the class for six months.

Cameron： What was it about derby that drew you in， versus other things that you could do to stay in shape？

Jess： I dont love the gym. Id seen derby before. It was hard to come in cause I was really scared， but now Im doin it.

Cameron： What changes have you noticed since youve done this？

Jess： Ive lost 50 pounds since November. All of a sudden my body changed shape and my muscles and my legs are incredibly strong.

But thats not all you build here on the track.

Jess： It helps you conquer your fears， so its been helping with confidence…

Demolicious： Theres some people that come in here to lose weight. Whoa！

Jess： Probably easier ways to lose weight.

Cameron： Yeah.

Demolicious： Well， cause we dont encourage losing weight. We encourage being in great shape.

Jess： You can really start to push yourself in ways that you never thought you were gonna push yourself， and the ways that…that translates into your life.

“無敵破壞王”：因?yàn)槟阌幂喸诨?，移?dòng)速度非?？?，這很刺激，產(chǎn)生興奮感的激素在上升。它讓人幾乎覺得塑身造型都不那么重要了，因?yàn)檫@運(yùn)動(dòng)本身簡直太棒了。

杰西·貝蒂參加訓(xùn)練班已經(jīng)半年了。

卡梅倫：既然都能起到塑身效果，相比其他運(yùn)動(dòng)，輪滑競賽的什么方面吸引你？

杰西：我不喜歡健身房。我之前看過輪滑聯(lián)賽。當(dāng)初選擇來這里我還真挺掙扎的，因?yàn)槲艺娴暮ε?，不過現(xiàn)在，我樂在其中。

卡梅倫：自從你玩輪滑開始，你注意到自己有什么變化嗎？

杰西：從2012年11月至今，我已經(jīng)瘦了50磅（約45斤）。突然間，我的體型已經(jīng)發(fā)生了很大的改變，身體的肌肉，腿部都強(qiáng)壯起來。

但是，你在滑道上還不僅僅得到這些。

杰西：它還幫助你克服自己的恐懼，所以對建立自信很有幫助……

“無敵破壞王”：有一些人來這是為了減肥的。哇！

杰西：可能有更容易的減肥方式。

卡梅倫：對。

“無敵破壞王”：嗯，因?yàn)槲覀儾还膭?lì)減肥。我們鼓勵(lì)的是保持好的身形。

杰西：你真的會(huì)開始逼迫你自己選擇一些你以前從未嘗試的方式，而這樣的轉(zhuǎn)變也會(huì)反映在你的生活之中。
