Half-kneeling cable extensions add a hip stability challenge to overhead tricep work by having you kneel on one knee. This asymmetric stance forces core engagement and prevents compensatory movements. The exercise targets the tricep long head through full overhead extension.
When to use it
Use for strict tricep isolation with core engagement.
Who it's for
Intermediate lifters wanting combined tricep and core work.
Kneel with one knee down and one foot forward facing away from a low cable. Hold the rope behind your head and extend your elbows to press it forward and up. Keep your torso upright and core braced—no swaying allowed. Switch your kneeling leg each set for balance.

Set cable pulley to low position with rope.
Kneel with one knee down facing away from cable.
Hold rope behind head with elbows bent.
Extend elbows pressing rope forward and up.
Squeeze triceps at full extension point.
Control back to starting position slowly.
Half kneeling position engages core heavily.
Eliminates lower body momentum completely.
Great for building tricep long head.
Use half-kneeling extensions when you want combined tricep and core work, or for variety from standard kneeling or standing extensions. They work well for athletic training where integrated stability matters. Program after compound pressing when you want strict isolation with added challenge.
Arching lower back during extension.
Changing your back position during the Half Kneeling Cable Extension can alter the movement and make the load harder to control. Brace your midsection and keep the torso position called for by the exercise.
Letting elbows flare out wide.
Letting your elbows drift away from the intended path during the Half Kneeling Cable Extension can change which muscles carry the load. Use the elbow position described in the setup cues and keep it consistent through each rep.
Using momentum from hips or torso.
Bouncing or using momentum during the Half Kneeling Cable Extension makes the movement harder to control and can shift work away from your Triceps (long head). 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. Rest 60 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 Half Kneeling Cable Extension could sit inside a complete workout. Your plan may use different movements after Ely checks your assessment.
