chin-ups

一种锻炼手臂和背部的练习,悬垂于横杠上,靠自身力量上拉。更严格的定义标准包括:手臂从完全伸直开始,下巴需接触杠下缘,或颈部接触杠。手掌可朝向任意方向。

(US) An exercise done for strengthening the arms and back, in which one lifts one's own weight while hanging from a bar. It can be defined more restrictively on criteria like the arms starting at lock-out, or the chin requiring contact with the bottom of the bar, or touching the neck to the bar. Palms may be facing in any direction.
