Decline Close-Grip Bench To Skull Crusher
Also works: Chest · Shoulders
A two-part rep on a decline bench: press the close-grip barbell from your lower chest to lockout, then without racking it lower the bar to your forehead and extend back out. One rep loads the triceps at both the elbow-extension and the shoulder-extension end of their job.
Own the movement
Set up first, then execute. Every cue below is something you can check on your next set.
Before the first rep
- Set the decline to 15-30 degrees and lock your legs firmly under the pads before you touch the bar.
- Take a grip slightly inside shoulder width, thumbs wrapped, wrists stacked over the forearms.
- Have a spotter hand you the bar. Reaching back and up to unrack on a decline is the moment shoulders get hurt.
- Start with the bar at arm's length over your lower chest and your elbows pointing at your hips, not out sideways.
- Load conservatively — the skull crusher half, not the press half, decides the weight you can use.
Every rep
Breathing & tempo — Breathe in as the bar comes to the chest, out as you press; breathe in again as it lowers to the forehead, out as you extend. Two seconds down on both halves, controlled up. Never rush the extension.
Before you load it
- Use a spotter. This is the one triceps movement where a failed rep can put a bar on your forehead, and the decline position gives you no way to sit up out of it.
- Stop the set at the first rep where the upper arms move during the extension. Grinding a fatigued skull crusher is how elbow tendons get injured.
- Skip the decline entirely if you get dizzy or feel pressure in your head when inverted. A flat-bench version of the same pairing works nearly as well.
Sets, reps & load
Where to start, and what to change when it stops being hard.
Start at around 30 kg total including the bar, or roughly 40% of your close-grip bench, and add 2.5 kg only when both halves of every rep look identical. The extension is always the limiter — if you can add weight and still press easily but the skull crusher half gets sloppy, you have gone too heavy. An EZ bar is kinder on the wrists than a straight bar for this pairing.
What goes wrong
The errors that show up most often, and the cue that fixes each one.
Pick the weight you can control for the skull crusher half with strict upper arms, which is usually 40-50% of your close-grip bench. The press portion should feel easy; that is correct.
Fix the elbows in space and think of the forearms as the only moving part. If you cannot keep them still, drop 5 kg and do the extension half in front of a mirror for a set to feel the position.
Hook your ankles firmly under the pads and press your heels back into them before unracking. If your body creeps up the bench between reps, the incline is too steep or the pads are set too far apart.
Aim the bar for a point just behind the crown of your head, so the arc passes over your forehead and never above your neck. Stop the set the moment you cannot hold that line.
Why bother
The triceps' long head crosses the shoulder as well as the elbow, so it is never fully worked by a press alone. Combining a close-grip press with a skull crusher in the same rep covers both: the press loads the elbow extension heavily near lockout, the extension portion loads the long head where it is stretched. You get two distinct stimuli without putting the bar down.
The decline angle is the part people underrate. It keeps your upper arms roughly vertical relative to gravity at the top of the extension, so tension stays on the triceps at the point where a flat-bench skull crusher goes slack. It also drops your shoulders below your hips, which reduces the shoulder strain of the pressing half.
Where it fits
Second movement on a pressing day, or the opener on an arm day, for 3-4 sets of 6-10 combined reps. Because each rep is two movements, the set takes twice as long under tension — count that against your total triceps volume. Do not stack it with skull crushers or dips in the same session.

Asked and answered
Is combining two movements actually better than doing them separately?
It is more time-efficient and it keeps the triceps under tension for longer per rep, which is a real hypertrophy advantage. It is not better for strength: you are forced to use the weight the weaker half allows, so the press portion is undertrained. If your goal is a bigger bench, do close-grip presses heavy and skull crushers separately.
Straight bar or EZ bar?
EZ bar, for most people. The skull crusher half asks your wrists to hold a pronated grip at the end of a long lever, and the angled grip takes the twist out of that. Use a straight bar only if your wrists are genuinely comfortable and you want the slightly longer range at the forehead.
Why decline instead of flat?
The decline keeps tension on the triceps at the top of the extension, where a flat-bench skull crusher lets the bar stack directly over the elbow and go momentarily weightless. It also spares the shoulder in the pressing half. The cost is a harder unrack and the need for a spotter.
How many reps counts as one rep?
One press plus one extension is one rep. Log it that way and expect the number to be low — 6 to 10 of these is a genuinely hard set, and the time under tension is closer to a set of 16 single movements.
