'Increased amounts of sit-ups may exacerbate any tightness in the flexor chain (muscles along the front of the body),' she explained. 'This in turn can lead to a weak lower back, putting pressure on the spine over time.'

“增加仰卧起坐的数量可能会加剧屈肌群收缩(身体前部位的肌肉)，她说，“这反过来会损伤腰背部，长此以往会对脊柱造成压力。

And she's got science to back her up. Texas Back Institute found that crunches put an unhealthy strain on the back at its weakest point, meaning that focusing solely on the exercise can lead to lower back pain.

她的说法是有科学依据的。德克萨斯州脊柱研究所发现，仰卧起坐会给背部最弱的部位造成不利于身体的压力，这就意味着仅仅靠仰卧起坐会造成腰背部疼痛。

 

 

Joslyn recommended trying planks, side planks, and hollow holds, which she likens to a 'reverse plank on the floor'.

乔斯琳推荐平板支撑、侧平板式和空心支撑。她将空心支撑比喻为在地板上做反向平板。

Those exercises strengthen the 'deep inner core muscles' and don't harm your back, she said - so they're a win-win.

她表示，这些锻炼会加强“深层的内在核心肌肉，不会对背部造成损伤，因此实属双赢的锻炼方法。
