下面這一段應該蠻簡單的
他是另外用方格補充的小技巧
大家自己看都會懂~
那個bungee cord我想應該是彈力繩之類的東西
可以拿來高空彈跳的吧~
不知要去哪裡搞到這種東西
==============================
ONE-ARM LOCK-OFF TIPS
1. Focus on pulling the bar toward your armpit.
2. Lift your knees to waist height while in the lock-off.
3. Try to keep breathing while holding a lock-off.
4. If at first you have difficulty holding the lock-off, stand in a loop of
bungee cord or use one finger of the other hand.
5. Do not work this exercise on a fingerboard.
