Chain Handle Extension
A lying triceps extension performed with two cable handles clipped to the middle of hanging chains. The load builds as the chains lift off, and the free-swinging handles force each arm to stabilise on its own — an accessory for lifters whose triceps quit at lockout rather than at the stretch.
Own the movement
Set up first, then execute. Every cue below is something you can check on your next set.
Before the first rep
- Clip a single-hand cable attachment to the middle link of each chain so the chain hangs in a U on both sides of the handle.
- Lie flat on the bench and have the chains hang beside you rather than across your body.
- Press the handles up until your upper arms point straight at the ceiling — vertical, not angled back over your face.
- Pin your elbows shoulder-width apart and keep the shoulder blades retracted against the pad.
- Take a pronated grip and let the chain settle before the first rep so you are not fighting a swing.
Every rep
Breathing & tempo — Inhale as the handles lower and the chain settles, exhale through the extension. Two seconds down, one second held at lockout, controlled up.
Before you load it
- Keep the chains clear of your head and neck on the descent — a slipping handle drops onto your face, not onto the floor.
Sets, reps & load
Where to start, and what to change when it stops being hard.
Start with a single light chain per handle — 5-8 kg is plenty for most people, since the load feels far heavier at lockout than the number suggests. Progress by adding links or shortening the hang so more weight lifts off, and only once you can hold a one-second lockout on the last rep of every set.
What goes wrong
The errors that show up most often, and the cue that fixes each one.
Imagine squeezing a ball between your elbows and keep the upper arms vertical. Drop a chain link if you cannot hold the position for the whole set.
Finish every rep with the elbows straight and every link airborne, then hold it for a count. Reduce the hanging weight until that lockout is achievable on the final rep.
Lower until the chain touches down and rests for a fraction of a second before you reverse. A dead-stop bottom removes the swing entirely.
Treat it as an isolation exercise: 8-12 reps, controlled tempo, elbows fixed. Heavy singles here punish the elbow joint and give you nothing a board press would not give you more safely.
Why bother
A dumbbell or EZ-bar extension is hardest with the elbow bent and nearly weightless at lockout, which is the opposite of where a bench press fails. Chains reverse that: the more links you lift off the floor, the heavier it gets, so peak tension lands exactly at full elbow extension where the long head is shortest.
The handles matter as much as the chains. Because each hand holds an independent, freely swinging load, you cannot let the stronger arm carry the set and you cannot cheat with shoulder movement — the handle simply drifts. That makes this a genuinely unilateral triceps drill wearing the clothes of a two-arm exercise.
Where it fits
Second or third movement on an upper-body day, after your press. Three or four sets of 8-12, twice a week at most. It is a supplement to heavy pressing, not a substitute — if you only have time for one triceps accessory and your bench dies off the chest, close-grip work serves you better.

Asked and answered
Why use chains instead of dumbbells for extensions?
Because a dumbbell extension is almost weightless at lockout, and lockout is where most bench presses fail. Chains put maximum tension at full extension, which matches the strength curve you are trying to fix. For general triceps size, dumbbells are simpler and just as effective.
Can I do this without chains?
A close approximation is a band-resisted extension anchored under the bench, which also gets heavier at the top. Cable lying extensions give constant tension but not an ascending curve. If you have neither, do skull crushers and accept that the top of the range is under-loaded.
Does it hurt the elbows?
It is easier on them than a straight-bar skull crusher, because the handles let the wrists and forearms rotate to a natural position and the load is lightest in the deep-stretch position that usually aggravates the joint. If it still bites, shorten the range and stop before the elbow is fully flexed.
How heavy should the chain be?
Light. Judge by whether you can hold a one-second lockout on the last rep of a set of ten. Most lifters overload this and end up swinging, which removes both the isolation and the point of the ascending resistance.
