Angling to get the abs of a Victoria's Secret model? One personal trainer insists that sticking to sit-ups won't get you there.

想要练成“维多利亚的秘密”模特的马甲线？一位私人教练告诉你坚持做仰卧起坐不能让你如愿以偿。

Trainer Joslyn Thompson Rule said that crunches¹ and sit-ups are not the way to tone your tummy, and even buckling² down and doing up to 500 a day is unlikely to get you closer to your six-pack goals.

教练乔斯琳·汤普森·鲁尔表示，单纯只做仰卧起坐不能练出腹肌，甚至每天做500个仰卧起坐也不能让你实现六块腹肌的目标。

'Just doing sit-ups alone won't get you rock hard abs because you're only working to strengthen one singular area, which is like trying to build the outer layers of a house with no foundations underneath,' she explained.

她解释说，“只做仰卧起坐不能练腹肌，因为你仅仅是在锻炼一个身体部位，这就好比是为一个还没有地基的房子修建外墙。”

So what exactly do sit-ups do? Joslyn said they work your 'external muscles', but don't actually build up the core or the obliques³ that give you that washboard look.

那么仰卧起坐到底有什么用？乔斯琳说，做仰卧起坐锻炼了“外部肌肉”，实际上对斜肌没有作用，而后者才是练出马甲线的关键。

That means that unless you're doing sit-ups as part of a greater work-out routine - like with cardio and planks⁴ - you shouldn't expect to see any visible results when looking at your tummy in the mirror.

这意味着，除了仰卧起坐，还要定期进行其他健身活动，比如有氧运动、平板支撑，否则就别指望着对着镜子里的肚子能看出任何效果。

Joslyn also stressed the importance of a healthy diet, which is the foundation of looking more muscular in the middle. Exercise - even when you're doing more ab-effective workouts - can only go so far if you're not eating right.

乔斯琳也强调了健康饮食的重要性，健康饮食是锻炼腹肌的基础。如果你饮食不合理，即使是做一些更有助于练腹肌的运动，也只会收效甚微。
