Cable Concentration Extension On Knee
Cable Concentration Extension On Knee Exercise Description
Cable Concentration Extension (on knee) is a single‑arm elbow‑extension exercise that targets the triceps brachii. Bracing the back of your upper arm against the inside of your thigh (just above the knee) minimizes shoulder movement, helping you focus on pure elbow extension. The cable’s consistent line of pull provides steady resistance through the full range of motion, encouraging controlled reps and even tension. Maintain a neutral spine with light scapular retraction to keep the shoulder complex stable while the forearm moves. This variation is useful when you want precise technique and a strong mind‑muscle connection for the triceps without momentum.

How To Do The Cable Concentration Extension On Knee Exercise
‘- Set a low pulley and attach a single D‑handle.
– Sit facing the stack, feet about shoulder‑width, knees bent; take the handle in one hand.
– Hinge forward slightly and plant the back of your upper arm against the inside of the same‑side thigh, just above the knee.
– Set ribs down, spine neutral; lightly retract/depress the scapula. Keep wrist neutral.
– Start with the elbow flexed and the forearm aligned with the cable; upper arm stays vertical and fixed against the thigh.
– Extend the elbow by pressing the handle away until the arm is straight but not locked; do not let the upper arm lift off your thigh.
– Briefly hold the end position; return under control by flexing the elbow, keeping the wrist stacked.
– Avoid torso rotation, shoulder shrugging, or letting the elbow drift inward/outward.
– Breathe steadily; don’t hold your breath.
– Switch sides and repeat.
Cable Concentration Extension On Knee Tips
‘- Brace the back of your upper arm firmly against the inside of your thigh just above the knee to minimize shoulder movement.
– Keep your upper arm vertical and fixed against your thigh; do not let it lift off as you extend or flex.
– Align your forearm with the cable at the start so the resistance matches your elbow’s line of movement.
– Maintain ribs down and a neutral spine with light scapular retraction/depression to keep the shoulder complex stable.
– Keep your wrist neutral/stacked on the handle throughout the movement.
– Extend the elbow until the arm is straight but not locked, then briefly hold the end position.
– Return under control by flexing the elbow, resisting the pull of the cable rather than letting it yank you back.
– Avoid torso rotation, shoulder shrugging, and letting the elbow drift inward or outward as you move.
– Breathe steadily throughout the set and avoid holding your breath.
Cable Concentration Extension On Knee Beginner Introduction
Cable Concentration Extension (on knee) is a cable‑based arm exercise that spotlights the triceps while limiting help from the shoulder. The lifter sits in front of a low pulley, using one arm at a time, with the upper arm supported against the inner thigh near the knee. This supported position reduces extra motion through the shoulder so most of the work centers on bending and straightening the elbow. Because the cable pulls from a low point, tension stays on the working arm throughout the motion, encouraging smooth, deliberate reps.
The movement emphasizes a tall, steady torso and a relaxed, natural curve through the back, with the shoulder area gently set so it stays quiet as the forearm moves. The wrist stays in line with the forearm while the handle travels, creating a clear feeling of effort through the back of the upper arm. Regular, unforced breathing and attention to a still trunk highlight control and precision, making this variation especially useful when practice, form awareness, and triceps isolation are the main goals.
