Set a bench at 45-75 degrees, lie back, and take a barbell overhead so the arms line up with your torso rather than pointing at the ceiling. Lowering it behind your head from there keeps the shoulders flexed for every rep, which loads the long head of the triceps in a lengthened position a flat-bench skullcrusher never reaches.
Set up first, then execute. Every cue below is something you can check on your next set.
Breathing & tempo — Inhale as the bar travels behind your head, exhale as you extend. Three seconds down, a one-second hold in the stretch, one second up.
Where to start, and what to change when it stops being hard.
Start with an empty EZ bar or a 20 kg barbell and nothing else for the first two sessions — the stretched position is deceptively hard and elbow soreness shows up a day later. Add 2.5 kg total once 15 reps are clean with a still upper arm. Reaching 40 kg for a controlled set of 12 is a strong intermediate mark.
The errors that show up most often, and the cue that fixes each one.
Keep the upper arms glued to the line of your torso all set. If they migrate, drop 5 kg — the swing is a way of shortening the lever and the long head loses the stretch that justified the incline.
Use at least 45 degrees. Below that the shoulder is barely flexed and you have made an awkward skullcrusher rather than an overhead movement.
Pull the front ribs down and brace before each rep. If the back still comes off the pad, the load is coming from the torso instead of the elbows.
Expect roughly 20-30% less. The triceps are working from a lengthened position at a longer lever; matching your flat-bench load here means the reps are being shortened somewhere.
The long head attaches above the shoulder joint, so it is only fully lengthened when the arm is overhead. The incline holds that shoulder flexion for the entire set — the arm stays in line with the torso from the first rep to the last, rather than drifting back to vertical the way it does on a flat bench.
Doing it on a bench rather than seated upright also removes the balancing problem. With your back supported at an angle you cannot arch away from the load, so the elbows are the only thing that can give, and you can honestly compare loads from week to week.
Second movement on a push or arm day, 3-4 sets of 10-15, after your heavy pressing but before pushdowns. One overhead movement per week is enough for most people: the long head under stretch produces genuine soreness and the elbow tendons need the recovery time.
No kit, too hard, or too easy — here's where to go instead.
Between 45 and 75 degrees. Steeper puts the arm nearer true overhead and gives the long head more stretch, but it also demands more shoulder mobility. Start at 45, and move steeper only if your shoulders reach the position without your ribs flaring.
For the long head, yes — the shoulder stays flexed so that head is trained lengthened rather than short. For total load moved, the flat version wins. The sensible answer is to alternate them in blocks rather than argue about it.
EZ bar for most people, because a close pronated grip on a straight bar loads the inner elbow and the wrists. Use the straight bar only if it genuinely feels fine — there is no strength advantage to earn by tolerating it.
Either the bench is too steep for your current shoulder mobility, or the bar is drifting into a wide arc and turning the rep into a pullover. Reduce the angle to 45 degrees, keep the bar close to your head, and stop the descent where the stretch is in your triceps rather than the front of the shoulder.
