Cable concentration curls combine the strict isolation of concentration curls with the constant tension of cables. The cable maintains resistance throughout the entire range of motion, including at the top where dumbbells would lose tension. This enhanced top-end tension makes cable concentration curls excellent for peak contraction.
When to use it
Use for focused isolation with constant tension.
Who it's for
Intermediate lifters wanting enhanced concentration curl.
Brace your elbow firmly against your inner thigh—this is your anchor point that should not move. Sit facing the cable machine at a distance that keeps tension even at full extension. Squeeze hard at the top where the cable creates maximum tension.
Also targets: Forearms, Brachialis

Set cable pulley to lowest position.
Sit facing machine with legs spread.
Brace elbow against inner thigh.
Grip handle and extend arm toward pulley.
Curl handle toward shoulder.
Squeeze and lower with control.
Cable maintains tension throughout range.
Brace elbow firmly against thigh.
Focus on peak contraction.
Use cable concentration curls when you want concentration curl isolation with enhanced constant tension. They work well as a finishing exercise for high-rep pump work, or when you want to maximize time under tension for metabolic stress.
Moving elbow off thigh - breaks isolation.
Letting your elbows drift away from the intended path during the Cable Concentration Curl can change which muscles carry the load. Use the elbow position described in the setup cues and keep it consistent through each rep.
Sitting too far from cable - awkward angle.
On an upper-body pulling movement like the Cable Concentration Curl, this mistake can shift work away from your Biceps brachii. Keep your torso stable and guide the load through the intended pulling path.
Using body momentum - defeats purpose.
Bouncing or using momentum during the Cable Concentration Curl makes the movement harder to control and can shift work away from your Biceps brachii. Use a load you can move smoothly through the intended range.

These ranges illustrate ways to organize training. They are not an individual prescription. Adjust them for the exercise, your experience, and the rest of your program.
Heavier loads can be useful for developing maximum strength. The range shown is an example, and the load must match your current technique and capacity.
Muscle growth can occur across different loads and repetition ranges. This example is not a uniquely effective zone; your overall program and effort also matter.
This is an example of a longer set. A repetition target alone does not establish joint safety or whether the exercise is appropriate for you.
Example: 3 sets of 12-15 reps per arm. Rest 30-45 seconds.
Background for resistance exercises: the 2026 ACSM position stand covers healthy adults, and a load-comparison review found similar muscle growth across loads in studies using sets taken to muscular failure. These findings do not validate every exercise-specific range shown here or require training to failure.
This is one example of how Cable Concentration Curl could sit inside a complete workout. Your plan may use different movements after Ely checks your assessment.
