【单词例句】
◇ Truth: As opposed to sit-ups, which target only your abdominal muscles, planks recruit several groups of muscles along your sides, front, and back. If you want a strong core -- especially the kind that would give you six-pack-like definition -- you need to challenge all of these muscles.Sit-ups or crunches strengthen just a few muscle groups.
事实：仰卧起坐只能针对你的腹部肌肉，而平板支撑则要用到你侧面、正面和背部的几组肌肉。所以如果你想拥有强壮的核心肌肉，尤其是想要练出6块腹肌，你需要锻炼到所有的这些肌肉。仰卧起坐只能锻炼到少数几个肌肉群。
