Cable Concentration Extension On Knee
Cable Concentration Extension On Knee Exercise Description
The Cable Concentration Extension (on knee) is a single‑arm triceps isolation exercise performed with a low cable while the upper arm is braced against the inside of the thigh near the knee. The primary movement is elbow extension, targeting the triceps brachii while minimizing shoulder motion for precise, controlled reps. Bracing the arm on the thigh provides stability so the humerus stays relatively fixed and the elbow becomes the main hinge. Using a cable maintains a consistent line of pull throughout the range of motion when you position the bench so the cable aligns with the forearm. Keep a neutral spine and set the scapula to reduce unnecessary shoulder movement and encourage efficient force transfer. This variation is helpful for learning strict elbow mechanics and for emphasizing end‑range triceps contraction without momentum.

How To Do The Cable Concentration Extension On Knee Exercise
‘- Set a flat bench beside a low cable stack; attach a single D‑handle.
– Sit facing the pulley with feet wider than hip‑width so the forearm has space to move.
– Hold the handle in one hand with a neutral grip; hinge slightly at the hips with a neutral spine.
– Place the back of the upper arm against the inside of the same‑side thigh just above the knee; lightly retract and depress the scapula.
– Position the bench so the cable tracks in line with your forearm throughout the motion.
– Start with the elbow flexed (about 90–110°), wrist neutral, and upper arm fixed against the thigh.
– Exhale as you extend the elbow until the arm is straight without forcefully hyperextending; keep the shoulder quiet.
– Pause briefly in full extension, maintaining a neutral wrist and steady torso.
– Inhale as you control the return to the starting angle, keeping the humerus anchored to the thigh.
– Repeat on the other side, resetting alignment so the forearm and cable remain in line.
Cable Concentration Extension On Knee Tips
‘- Sit facing the pulley with your feet wider than hip‑width so the working forearm has room to move.
– Hinge slightly at the hips and keep a neutral spine throughout the set.
– Brace the back of your upper arm firmly against the inside of your thigh just above the knee to keep the humerus fixed.
– Lightly retract and depress your scapula to set the shoulder and minimize extra shoulder motion.
– Position the bench so the cable stays in line with your forearm through the entire range of motion.
– Start with the elbow bent around 90–110° and maintain a neutral wrist before you begin extending.
– Focus on extending only at the elbow, keeping the shoulder “quiet” and the upper arm glued to your thigh.
– Straighten the arm without forcefully hyperextending, then briefly pause in full extension for a controlled contraction.
– Control the return to the starting angle, keeping your torso steady and the humerus anchored to your thigh.
Cable Concentration Extension On Knee Beginner Introduction
The Cable Concentration Extension (on knee) is a focused arm exercise that isolates the triceps using a low cable setup and a flat bench. One arm works at a time while the upper arm rests against the inside of the leg near the knee, giving the limb a solid anchor. This support helps the elbow act as the main pivot point so the movement stays clean and centered on the back of the upper arm rather than turning into a swinging motion from the shoulder.
Because the handle is attached to a cable, tension stays present from the start of the push to the finish, encouraging smooth, steady reps. The body is arranged so the cable travels in the same direction as the forearm, helping reinforce a simple, repeatable path. With the torso held stable and the shoulder kept relatively quiet, this variation highlights careful elbow action and a strong squeeze at full extension, making it popular for learning controlled, mind‑muscle connection with the triceps.
