Cable Standing One Arm Triceps Extension
Upper arms, cable
A single-arm cable triceps isolation exercise done standing, extending the elbow while keeping the upper arm fixed.
Target: triceps. Also works: shoulders.
Steps
- Stand side-on to the cable machine and grasp the handle with one hand.
- Step away until the cable is taut, then raise your upper arm so it stays roughly parallel to the floor.
- Bend your elbow to bring the handle toward the side of your head while keeping your upper arm still.
- Extend your elbow to press the handle away until your arm is straight.
- Pause briefly with your triceps tight, then return under control.
- Complete all reps on one side, then switch arms.
Common mistakes
- Letting the elbow drift up and down during the rep
- Turning the torso to help move the handle
- Dropping the upper arm instead of keeping it level
- Using momentum and snapping the cable back
Breathing
