Cable Seated One Arm Concentration Curl
Cable Seated One Arm Concentration Curl Exercise Description
The Cable Seated One Arm Concentration Curl isolates the elbow flexors by bracing the upper arm against the inner thigh while curling a single cable handle from a low pulley. Primary emphasis is on the biceps brachii, with the brachialis and brachioradialis assisting; the forearm flexors stabilize the wrist. The cable’s consistent line of pull helps maintain tension throughout the range of motion, encouraging controlled reps without torso momentum when positioned correctly. The seated, supported setup minimizes shoulder and trunk contribution so you can focus on precise elbow flexion and full, controlled extension. Key technique points include a neutral spine, lightly packed shoulder, neutral wrist, and keeping the upper arm fixed against the thigh for a smooth arc of motion.

How To Do The Cable Seated One Arm Concentration Curl Exercise
‘- Set the cable to the lowest pulley and attach a single D‑handle.
– Place a flat bench a short distance from the stack; sit facing the pulley.
– Feet slightly wider than hips; hinge forward slightly with a neutral spine and level pelvis.
– Hold the handle in one hand with a supinated grip (palm up).
– Rest that elbow against the inside of the same-side thigh, just above the knee—do not press on the knee joint.
– Lightly retract and depress the shoulder blade to “pack” the shoulder; keep the upper arm still.
– Align the forearm with the cable so there’s tension at the start without the shoulder being pulled forward.
– Brace gently, then curl by flexing the elbow; keep the wrist neutral and the torso quiet.
– Stop when the forearm is near vertical or the biceps is fully shortened without letting the shoulder drift forward.
– Pause briefly, then lower under control until the elbow is almost straight—avoid locking out or losing shoulder position.
– Maintain even breathing; avoid shrugging, swinging, or letting the elbow slide off the thigh.
– Reset as needed for cable alignment and switch sides, duplicating the setup.
Cable Seated One Arm Concentration Curl Tips
‘- Sit facing the lowest pulley with feet slightly wider than hips, hinging forward with a neutral spine and level pelvis.
– Rest your curling-side elbow against the inside of the same-side thigh just above the knee, avoiding direct pressure on the knee joint.
– Lightly retract and depress the shoulder blade to “pack” the shoulder, and keep the upper arm fixed against the thigh.
– Align your forearm with the cable so there is tension at the start without the shoulder being pulled forward.
– Use a supinated (palm-up) grip and curl by flexing the elbow while keeping the wrist neutral.
– Keep the torso quiet throughout the curl, avoiding any swinging or use of body momentum.
– Stop the curl when the forearm is near vertical or the biceps feels fully shortened, without letting the shoulder drift forward.
– Pause briefly at the top, then lower the handle under control until the elbow is almost straight, avoiding locking out or losing shoulder position.
– Maintain even breathing and ensure the elbow does not slide off the thigh; reset your position and cable alignment as needed before switching sides.
Cable Seated One Arm Concentration Curl Beginner Introduction
The Cable Seated One Arm Concentration Curl is a strict, machine‑based curl that uses a low cable and bench to emphasize one arm at a time. The lifter sits facing the weight stack with the working arm resting against the inside of the leg, so the elbow moves through a smooth, curved path while the rest of the body stays quiet. The cable’s steady resistance encourages an even pull and return, rather than relying on swinging or torso motion to move the load.
With the upper arm supported against the thigh, effort shifts strongly into the biceps, with extra help from the smaller elbow‑bending muscles and the forearms for wrist stability. The setup highlights precise elbow movement, a steady back position, and a relaxed, low shoulder instead of shrugging. Because the line of pull remains consistent from start to finish, the exercise suits lifters who want a concentrated arm curl that emphasizes tension through the whole motion and rewards patience, control, and clean positioning on each repetition.
