The triceps extension is performed while standing or seated, by lowering a weight held above the head (keeping the upper arms motionless), and then raising it again. It can be performed with both arms, or one arm at a time. This is an isolation exercise for the triceps. It is also known as the french curl. Equipment: dumbbell(s), barbell, cable machine or triceps extension machine. Major variants: lying ~ (lying face up with the weights over the face), kickback (bent over with the upper arm parallel to the torso). -Wiki-
