健身英语翻译
Use a stability ball. Do your crunches on the ball to introduceinstability to your workout, which will improve your balance too. There arealso lots of core exercises that cathe way. Do this as often as you arecomfortable or at times when it won't look weird. You can bend forward from thehips or, if you're really into it, bend at the knees too and really "sink" out of the way.
请问第三句cathe way是什么意思,还有最后"sink" out of the way呢?
