健身英语jackknife sit ups，一句话和一个短语翻译
Do jackknife sit ups. Lie down flat with your back on the floor. Place your hands on the ground to your sides for balance; you can pick them up as you get used to the movement. Simultaneously raise your knees and torso so that your knees and face meet on an imaginary line extending from your pelvis to the ceiling.
请问on the ground to your sides 是什么意思，to是at的意思吗？pick them up 是什么意思？

Answer 1

平躺后，两手贴身侧，手掌贴地面 以找平衡。to的话，紧贴，接壤， at的话，只要两侧就行了，可以离身体很远。 pick them up 习惯了的话，做动作的时候，可以随着提起凌空。
