Preacher Curl Bench: Types, Pad Angles and Is It Worth It?

A preacher curl bench is worth buying if you train arms seriously at home and have already covered the essentials; if you haven't, an attachment for your adjustable bench or a couple of clever substitutions will get you most of the benefit for a fraction of the cost and floor space. What a preacher bench actually does is pin the back of your upper arm to an angled pad, which stops you swinging and forces your biceps to do the work right from the stretched bottom of the rep. This guide covers the types you can buy, why pad angle matters more than most listings admit, what separates a solid bench from a wobbly one, and how to set one up. If you want the exercise itself broken down step by step, our preacher curl technique guide covers form, muscles worked and variations.

The four types of preacher curl bench

Everything sold as a "preacher bench" falls into one of four groups. Which one suits you depends mostly on what you already own.

Type	What it is	Typical UK price	Best for
Standalone preacher bench	A dedicated frame with a seat, an angled arm pad and usually a bar catch	Roughly £60 to £300	Lifters with space who curl two or three times a week
Seated preacher station or machine	A selectorised or plate-loaded arm curl machine with a fixed path	Usually £1,000 and up	Commercial gyms; rarely sensible at home
Preacher attachment	A pad that slots into an adjustable bench, leg developer post or rack upright	Often bundled; standalone ones vary by brand	Anyone with a compatible bench or rack
Angled pad on a multi-gym	A preacher pad fixed in front of a low cable pulley	Comes with the multi-gym	Cable preacher curls with constant tension

Standalone preacher benches

These are the most common home option. You sit on a padded seat, rest your arms over a sloped pad and lift a dumbbell, EZ bar or barbell taken from a pair of hooks in front of you. Cheaper models are light, bolt-together frames; the better ones use heavier steel, a wider base and a seat that adjusts in more increments. A standalone bench does one job well, and that single-purpose design is both its strength and its weakness: it occupies a spot on the floor for something you'll use maybe 15 minutes a week.

Seated preacher stations

The arm curl machines you see in commercial gyms run a cam or lever arm in a fixed arc. They're comfortable and easy to load, but they're heavy, expensive and the fixed path doesn't suit every arm length. Unless you're fitting out a garage with a big budget, skip these.

Attachments for an adjustable bench or rack

Many adjustable benches now come with, or can take, a preacher pad that slots into the front post where a leg developer would go. Rack-mounted pads clip onto your power rack's uprights. If you already have a decent bench, this is usually the best value route, because you're adding one small part rather than another frame. Our best weight bench UK guide includes a bench sold with a preacher pad and leg developer if you're buying a bench anyway.

Angled pads on multi-gyms

Plenty of home multi-gyms put a preacher pad in front of the low pulley. Curling a cable over a pad keeps tension on the biceps through the whole rep, which a free-weight preacher curl can't do at the top. If you're choosing between a multi-gym and separate pieces, that's a point in the multi-gym's favour.

Pad angle: what it changes

This is the spec that matters most and gets mentioned least. The pad decides how far forward your upper arm tilts, and that decides where in the rep the weight feels heaviest.

A free weight pulls straight down, so the curl is hardest at the point where your forearm is horizontal. On a standard pad your upper arm tilts forward by roughly 45 degrees, which means your forearm reaches horizontal early, only about 45 degrees into the curl. The result: the bottom half of the rep, where your biceps are stretched, is the hard part, and the top is nearly free as your forearm approaches vertical. That stretch-biased loading is the main reason people want a preacher bench in the first place.

Pad setting	Upper arm position	Hardest part of the rep	Easiest part
Flatter pad (upper arm closer to horizontal)	Tilted well forward	The very bottom, at full stretch	Top half
Standard pad (about 45 degrees)	Tilted forward at roughly 45 degrees	Lower half	Top quarter
Vertical pad or the steep side of the bench	Hanging straight down	Middle of the rep	Bottom and very top

There's decent evidence that biasing the stretched position is a good use of your training time. In a 2025 study, trained lifters did one-arm preacher curls with one arm working only the bottom 70 degrees and the other arm using the full range for 8 weeks; mid-arm growth was similar, and the partial-range arm showed a small edge further down the arm (Havers et al., European Journal of Sport Science). A separate trial found lengthened partials and full-range reps built similar upper-arm muscle, and its authors concluded that people chasing size should emphasise the stretched position (Wolf et al., PeerJ). A standard 45 degree pad does that for you automatically.

Some benches give you two working faces: a sloped side and a near-vertical side. The vertical side moves the hard part higher in the rep and pairs nicely with one-arm dumbbell work as a second exercise, so a bench with both faces is worth a small premium.

What to look for when buying

Adjustability

Seat height is the setting that makes or breaks the fit. The top edge of the pad should sit snugly in your armpit with the whole back of your upper arm in contact. Look for a seat with at least four or five height positions, and if you're tall or short, check the listed seat height range against your torso rather than your overall height. An adjustable pad angle is a bonus; a fixed 45 degree pad is fine for most people.

Stability and build

Wobble ruins a preacher curl, because you end up bracing against the bench instead of curling. Things to check:

• Base footprint: a wider stance at the front, where the load sits, matters more than at the back.
• Listed maximum load, and whether it covers your bodyweight plus the bar you'll use.
• Tube gauge and the number of bolted joints; fewer joints generally means less play.
• Rubber feet that sit flat on gym flooring.
• A bar catch at a height you can reach from the seat without leaning out of position.

Footprint and storage

Standalone benches are compact compared with most kit, but they don't fold, and you need clearance in front of the pad for the bar to travel. Measure the space and compare it against the listed dimensions before ordering. If floor space is tight, an attachment for a bench you already own wins every time.

Pad comfort

Thin pads with hard edges dig into your armpits and triceps, and a pad that's too narrow lets your elbows slide off. A dense, slightly contoured pad wide enough for a shoulder-width EZ bar grip makes heavier sets far more comfortable.

Is a preacher curl bench worth it?

Our view is that a dedicated preacher bench sits low on the home-gym priority list. A rack, a barbell and plates, an adjustable bench and a set of dumbbells do far more for your whole body, and the preacher curl's main selling point (strict, stretch-loaded biceps work) can be replicated with what you already have. Buy one once the basics are sorted and you genuinely enjoy arm training, not before.

There's also no strong evidence that the preacher's shoulder position is magic. One trial found similar elbow flexor growth whether lifters curled with the shoulder flexed forward, as on a preacher pad, or extended back, as in an incline curl (da Silva Vendruscolo et al., Sports Health). It used light loads with blood flow restriction, so it isn't the final word, but it suggests you're not missing out if you choose an alternative.

Good substitutes:

• Bench-back preacher curl. Set an adjustable bench to a steep incline, kneel or stand behind it and drape one arm over the backrest for single-arm dumbbell curls.
• Spider curl. Lie chest-down on an incline bench with your arms hanging vertically; it loads the top of the curl, the opposite of a standard preacher. Our spider curl guide explains the setup.
• Incline dumbbell curl. Lie back on an incline bench so your arms hang behind your body for a deep long-head stretch.
• Cable preacher curl. Put any bench or pad in front of a low pulley for tension through the whole range.

We cover all of these, plus a banded version, in our preacher curl alternatives article.

Two options worth a look on Amazon

If you've decided a dedicated bench earns its spot, the Gyronetics preacher curl bench is a simple standalone frame with an adjustable seat and a listed maximum load of 150kg. It was around £90 and in stock when we checked, though we haven't had one in our hands, so compare the seat range and dimensions with your space first.

If you'd rather buy one bench that does more, the Fostoy foldable adjustable bench comes with a removable preacher pad and a leg developer, and it folds away when you're done. It was a little over £100 when we checked. Bench-mounted pads tend to have more play than a dedicated frame, so expect to keep the weight sensible.

Pair either one with an EZ bar for the most comfortable wrist position; our best EZ bar UK guide covers bar weight, sleeve fit and grip.

Setting up a preacher bench correctly

Most bad preacher curls come from a bad setup rather than bad effort. Before your first set:

1. Set the seat height first. Sit down and raise or lower the seat until the top of the pad tucks into your armpits with your chest touching the pad's upper edge.
2. Check arm contact. The whole back of each upper arm, from armpit to just above the elbow, should rest on the pad. If your elbows hang off the end, the seat is too high.
3. Plant your feet. Feet flat and slightly wide so you can't push yourself up and back off the pad as the set gets hard.
4. Set the bar catch. Load the bar on the hooks at a height you can lift off without leaning out of position, then return it the same way.
5. Start light. Your biceps are weakest at full stretch, which is exactly where a standard pad loads them hardest. Pick a weight you can lower slowly to a near-straight arm without your elbows lifting off the pad.

Don't lock out aggressively at the bottom with a heavy weight. Lower under control to a slight bend, then curl back up. That's where most preacher curl elbow strain comes from, and a slower descent fixes it.
