CableBarSkullcrusher健身视频教程-三头肌锻炼

Cable Bar Skullcrusher

Use a bar attachment. The cable should be set all the way to the top of the machine.
Face away from the machine with your elbows up and the attachment just behind your head.
Extend at the elbows until you feel a contraction in your triceps and then flex at the elbow back to the starting position.
