英语翻译
Flex your abs to protect your back and contract the hip flexors—the muscles on the front of the kneeling leg—by imagining that you are going to kick forward with that foot or knee.
背景大概是要拉伸某一块肌肉.
问题的关键在于Flex 这个词应该翻译为放松，延展，拉伸还是收紧？

收缩腹肌保护背肌,并收缩跪着的前膝上的臀屈肌,做法是想像你在用这只脚或膝做欲前踢状.
补充:从上下文来看,以及如果你自己按照说明去体会一下,应该是收缩,收紧的意思,体会一下动作就能知道了,腹肌要紧张才能做得到吧,这一点不必要专家吧
