Single Arm Tricep Cable Extension

Beginner Level of Difficulty

The single arm cable extension is a beginner exercise that targets the triceps and is suitable for any fitness level.


Picture of Triceps


Triceps are an often forgotten muscle group. Triceps are located on the opposite side of the biceps at the back of the upper arm. Well strengthened and defined triceps make the arm look bigger and sleeker (reducing the "flabby arm" look).

Picture of Shoulders


The shoulder is the most movable joint in the body. However, it is an unstable joint because of the range of motion allowed. This instability increases the likelihood of joint injury, often leading to a degenerative process in which tissues break down and no longer function well.
