# Best Ab Machine 2026: 10 Ranked, and the 440 lb Claim Four Sellers Share Source: https://www.ranked10.co.uk/fitness/best-ab-machines Published: 2026-09-18 | Updated: 2026-09-19 | Prices checked on Amazon UK on 2026-09-17 Four ab machine listings in this round-up promise the same 440 lb (200 kg) load rating. The cheapest of them costs £39.99; the dearest costs £155.47. That is a 3.9x price spread for one identical marketing number, which tells you the figure is copy rather than engineering. The RELIFE is the clearest case: its bullet claims "up to 440 lbs", while its own title and specification table say 180 kg — 397 lb. Same product, 43 lb apart. Meanwhile, two listings for the same ZELUS coaster sit at £89.99 with 46 reviews and 4.6 stars each, yet one histogram logs eight 1-star ratings and the other three. We ranked ten of the best ab machine options on Amazon on three honest criteria: review volume and its histogram rather than the star average alone, stated load ratings cross-checked line by line against the specification table, and whether the frame, the warranty and the folded dimensions suit a spare room rather than a gym floor. ## The ranking ### 1. MERACH Ab Machine, Adjustable — 2 Inclines, 5 Heights - Price: £65.99 | Amazon rating: 4.6 from 2,158 ratings - Full review: https://www.ranked10.co.uk/fitness/best-ab-machines/merach-ab-machine-adjustable - Buy on Amazon: https://www.amazon.co.uk/dp/B0DXKSG22R?tag=ranked10-21 First on review volume: 2,158 ratings at 4.6, two inclines, five heights and a folding frame at £65.99 — though no warranty is listed. This sits first because of the review base: 2,158 ratings at 4.6, with 80% of them five-star. Nothing else here comes close on volume — the next largest is 1,102. The ab machine also ranks 2nd in Amazon's Home Gym Systems category, a narrower and more competitive shelf than the generic Sports & Outdoors table. In practice you get two incline settings and five height adjustments, silent rollers, and thick sponge padding at the knees and elbows. The LCD tracks counts, time and calories. Unit weight is 9.17 kg and the frame material is listed as ABS plastic rather than steel, which matters before you judge it on looks alone. That said, the specification lists the product warranty as "No". On a £65.99 foldable ab machine that is the single most important line in the listing, and it is the reason to think twice if you want cover. It also suits lighter users better: no maximum user weight is published anywhere. Pros: 2,158 ratings at 4.6, with 80% five-star; 2 incline settings and 5 height adjustments; Folds for storage; 9.17 kg; LCD shows counts, time and calories; 2nd in Amazon's Home Gym Systems category Cons: Specification lists "Product Warranty: No"; Frame material is ABS plastic, not steel; No maximum user weight published; 4% one-star and 1% two-star — roughly 86 one-star reviews at this volume ### 2. FLYBIRD Abdominal Trainer, 150 kg Load, Foldable - Price: £99.99 | Amazon rating: 4.5 from 1,102 ratings - Full review: https://www.ranked10.co.uk/fitness/best-ab-machines/flybird-abdominal-trainer - Buy on Amazon: https://www.amazon.co.uk/dp/B0GJ3GNM64?tag=ranked10-21 Second at 4.5 from 1,102 ratings, with a 150 kg rating that matches its own specification table — the opposite of the 440 lb group. Second on 1,102 ratings at 4.5. Its headline figure is 150 kg, which the spec table repeats as 330 lb — one of the few listings here where the marketing number and the specification agree. By contrast, that consistency is exactly what the 440 lb group lacks. The movement is different from the rest: FLYBIRD describes a bottom-up action rather than a forward slide, intended to take load off the neck. You get four tilt angles combined with five heights, 3cm foam padding, and a dual-lane triangular frame in commercial-thickness steel. At 8.16 kg it is one of the lighter abdominal trainer machines here. The catch is the sales rank: 54,948 in Sports & Outdoors, well behind the cheaper MERACH at 9,271. Either way, the warranty is split — one year on the frame, 30 days on the rest — so check what the shorter term actually covers before ordering. Pros: 150 kg stated in the title and repeated as 330 lb in the spec; 4 tilt angles and 5 adjustable heights; Dual-lane triangular steel frame with 3cm foam padding; 8.16 kg and folds for storage; 1,102 ratings at 4.5 Cons: £99.99 — second dearest item on this list; Sales rank 54,948 in Sports & Outdoors; Leads only the narrow "Fitness Bottom Muscle Toners" category; Frame covered 1 year; other parts just 30 days ### 3. MERACH Dual Track Ab Machine, Curved Rails, Foldable - Price: £70.00 | Amazon rating: 4.5 from 450 ratings - Full review: https://www.ranked10.co.uk/fitness/best-ab-machines/merach-dual-track-ab-machine - Buy on Amazon: https://www.amazon.co.uk/dp/B0GRTYSYQW?tag=ranked10-21 A curved dual-track design at £70 with 330 lb stated twice and a 12-month warranty — the most consistent load rating under £100 here. Third on 450 ratings at 4.5. The published limit is 330 lb, repeated in the spec table under "Tension Supported" — a lower ceiling than the 440 lb claims above it, but stated twice and consistently. It ranks 3rd in Home Gym Systems. This ab trainer machine uses a curved arc track rather than a straight rail, which MERACH says mimics a natural crunch. The dual-track frame is triangular for stability, the rollers are described as silent, and the box includes two elastic ropes and a monitor. At 9.4 kg it is the heaviest of the four MERACH listings. Worth noting: a 12-month warranty is stated here, while the cheaper MERACH at £49.99 carries the same and the top-ranked one lists none at all. That said, 330 lb is the honest ceiling — anyone close to that figure should be looking at the steel-framed ab machine further down this list, not the ABS ones. Pros: 330 lb published in the bullet and repeated in the spec; 12-month warranty listed; Curved dual-track frame with triangular bracing; Includes two elastic ropes and an LCD monitor; 450 ratings at 4.5; 3rd in Home Gym Systems Cons: Publishes 330 lb where a £39.99 listing claims 440 lb; 9.4 kg with no folded dimensions given; One bullet markets it for postpartum recovery with no supporting detail; 4% one-star ratings ### 4. MERACH Sit Up Machine, 3 Resistance Levels, £49.99 - Price: £49.99 | Amazon rating: 4.6 from 194 ratings - Full review: https://www.ranked10.co.uk/fitness/best-ab-machines/merach-ab-machine-trainer - Buy on Amazon: https://www.amazon.co.uk/dp/B0G8K6DVR4?tag=ranked10-21 The lightest and cheapest folding option here: 5.2 kg, folds in 5 seconds, 3 resistance levels, £49.99, and 4.6 from 194 ratings. Fourth despite a 4.6 average, because 194 ratings is a tenth of the leader's. The spec reads well: 330 lb maximum user weight, three adjustable resistance levels with auto-rebound, and a heavy-duty steel frame with ABS parts. A 1-year warranty is stated. In practice this is the most portable piece of sit up exercise equipment here — 5.2 kg, a 5-second fold, and a footprint of 17.8in by 17.6in. The handles are 2-inch foam. The listing claims arm, leg, glute and back exercises beyond core work, and on a frame this light that full-body framing is the most generous claim on the page. The catch is a copy error in the listing itself: the customer-service bullet refers to a "rebounder trampoline", which this is not. Even so, if you want something that slides under a bed rather than occupying a corner, this is the cheapest route to a folding frame with a stated warranty. Pros: 4.6 from 194 ratings; 5.2 kg and folds in 5 seconds; 3 resistance levels with auto-rebound; 1-year warranty stated; 330 lb max user weight; 2in foam handles; 17.8in x 17.6in footprint Cons: 194 ratings — a small base next to the top three; One bullet references a "rebounder trampoline" — a copy error; Multi-target exercise claims on a 5.2 kg frame; No folded dimensions published ### 5. BODY RHYTHM Dual-Track Ab Machine, 4 Heights, 440 lb - Price: £155.47 | Amazon rating: 4.5 from 128 ratings - Full review: https://www.ranked10.co.uk/fitness/best-ab-machines/body-rhythm-dual-track-ab-machine - Buy on Amazon: https://www.amazon.co.uk/dp/B0C1PRHQSF?tag=ranked10-21 The dearest item at £155.47, claiming the same 440 lb as a £39.99 frame — and its capacity appears in the title only, not the spec. Fifth and the most expensive ab machine on this list at £155.47, with 128 ratings at 4.5. Its title claims a 440 lb weight capacity — the same figure as a £39.99 Panana, a 3.9x price difference for one identical number. Crucially, that capacity appears in the title only; it is not repeated in the specification table. The design is unusual: 120 curved dual-track sliders that separate, which the listing says engages more muscle than a single carriage, plus four adjustable heights. Item weight is 12.1 kg and dimensions are 44 x 93.1 x 94 cm, so it needs a fixed footprint. That said, the spec sheet carries filler — "Software Update Supported to Date: unknown" and a corded-electric power source on what is a manual piece of ab workout equipment. Two things to weigh. It ranks 201,990 in Sports & Outdoors, 129th in Home Gym Systems — the weakest position of anything here. And the final bullet is an international-products disclaimer confirming it ships from abroad, with separate terms and possibly different labelling. No warranty is stated anywhere on the page. Pros: 120 curved dual-track sliders with a split carriage; 4 adjustable heights and 4 resistance levels; LCD tracks calories, time and reps; 4.5 from 128 ratings; 12.1 kg alloy steel frame Cons: £155.47 — 3.9x the price of the £39.99 frame claiming the same 440 lb; No warranty stated; Listing's own disclaimer says it ships from abroad on separate terms; Rank 201,990 in Sports & Outdoors; spec table carries irrelevant fields ### 6. RELIFE Foldable Ab Cruncher, 180 kg Spec, 440 lb Claim - Price: £54.99 | Amazon rating: 4.3 from 278 ratings - Full review: https://www.ranked10.co.uk/fitness/best-ab-machines/relife-ab-workout-machine - Buy on Amazon: https://www.amazon.co.uk/dp/B0F243G548?tag=ranked10-21 A 180 kg specification sold under a 440 lb bullet — a 43 lb gap on the same page, at £54.99 with 278 ratings. Sixth on 278 ratings at 4.3 — the lowest average in the top six. This entry matters because of the contradiction: the bullet promises "up to 440 lbs", the title says 180kg, and the specification table says "Maximum Weight Recommendation: 180 Kilograms". 180 kg is 397 lb. That is 43 lb less than the bullet claims, on the same page, for the same product. Mechanically it is straightforward: 5 height settings and 2 incline levels, reinforced thickened rollers, NBR foam padding, an LCD showing reps and time, and a folding frame measuring 113 x 50 x 79 cm at 7.8 kg. Its sales rank of 5,166 in Sports & Outdoors is the strongest of anything in this list, and it sits 5th in Strength Training Upper Body Machines. As a result, buy this ab crunch machine for the 180 kg the specification table states, not the 440 lb on the bullet. At 4.3 it also carries 9% one-star ratings, the highest share here, so read the negatives before ordering. Anyone around 110 kg should look at a dual-track steel frame instead. Pros: 278 ratings at 4.3; 5 height settings and 2 incline levels; Folds to 113 x 50 x 79 cm; 7.8 kg; LCD tracks reps, counts and time; Best sales rank here: 5,166 in Sports & Outdoors Cons: Bullet claims 440 lbs while title and spec say 180 kg (397 lb) — a 43 lb gap; 4.3 is the lowest average in the top six; 9% of its ratings are one-star; No warranty stated in the specification ### 7. MERACH Adjustable Sit Up Bench, 136 kg Max - Price: £67.99 | Amazon rating: 4.2 from 160 ratings - Full review: https://www.ranked10.co.uk/fitness/best-ab-machines/merach-adjustable-sit-up-bench - Buy on Amazon: https://www.amazon.co.uk/dp/B0FG6YJK1P?tag=ranked10-21 The lowest stated limit in the list at 136 kg, on a sit-up bench with four length adjustments and a rebound spring system. Seventh at 4.2 from 160 ratings. The published limit is 136 kg (300 lb) — the lowest maximum user weight stated anywhere here, and 64 kg below the 200 kg claims further up. It is at least honest about it: the number appears in both the bullet and the specification. This is a bench rather than a slider. Four flexible length adjustments adapt it to different heights, and there is a rebound spring system to reduce back pressure, a padded seat and a foam roller backrest. Dimensions are 104 x 33.8 x 72.2 cm and it weighs 8.6 kg. Assembly is quoted at 15 minutes. At the same time, it carries the weakest review profile of the ten: 11% one-star and 3% two-star. That is a louder warning than the 4.2 average suggests, which means the score flatters it. It suits sit-ups, leg raises and air bikes at moderate bodyweight — not heavy loading. Pros: 136 kg limit stated in both the bullet and the specification; 4 flexible length adjustments for different heights; Rebound spring system, padded seat, foam roller backrest; 8.6 kg; assembly quoted at 15 minutes; 1-year warranty listed Cons: 136 kg is the lowest stated maximum in this list; 11% one-star and 3% two-star ratings; 4.2 average — second lowest here; 160 ratings, a small base ### 8. PAPIBLU Ab Trainer Machine with Display, Folding - Price: £59.99 | Amazon rating: 4.2 from 87 ratings - Full review: https://www.ranked10.co.uk/fitness/best-ab-machines/papiblu-ab-trainer-machine - Buy on Amazon: https://www.amazon.co.uk/dp/B0H1VKTD13?tag=ranked10-21 £59.99 for two inclines and five heights — but no maximum user weight is published anywhere on the page. Eighth at 4.2 from 87 ratings. The listing gives two inclination angles and five height adjustments, thick foam padding at knees and elbows, and quiet rollers — the same feature set as the RELIFE and MERACH frames at a similar price. Crucially, though, no maximum user weight appears anywhere in the specification. In practice that missing number is the decision point. Every other product in this top ten publishes a load rating; this one leaves it blank, so there is nothing to cross-check the marketing against. It weighs 9 kg and folds flat for storage under a bed or in a closet. Meanwhile, its category placement is odd — 46th in Leg Machines, which is not where buyers look for core equipment — and its overall rank is 105,604 in Sports & Outdoors. With 11% one-star ratings, it is one to buy only if you accept an unpublished load limit. Pros: 2 inclination angles and 5 height adjustments; Folds flat for storage; 9 kg; LCD tracks reps, time and calories; Quiet rollers and thick foam padding; 4.2 from 87 ratings Cons: No maximum user weight published anywhere; 11% one-star ratings; Rank 105,604 in Sports & Outdoors; listed under Leg Machines; 87 ratings — the second-smallest base here ### 9. Panana Foldable Ab Machine, 5 Levels, LCD Counter - Price: £39.99 | Amazon rating: 4.3 from 40 ratings - Full review: https://www.ranked10.co.uk/fitness/best-ab-machines/panana-foldable-ab-machine - Buy on Amazon: https://www.amazon.co.uk/dp/B0DCFGGRNV?tag=ranked10-21 The cheapest 440 lb claim here at £39.99, backed by only 40 ratings and a folding alloy-steel frame. Ninth, and the cheapest of the 440 lb group at £39.99. Its specification lists "Maximum Weight Recommendation: 440 Pounds" — the same figure as the £155.47 BODY RHYTHM, at roughly a quarter of the price. Only 40 ratings at 4.3 support it, the second-smallest sample here after the TYRSEN's 22. The build is simple: five frame-height settings to change the incline, a sliding knee carriage, non-slip feet, thick knee pads and foam-covered handles. The LCD shows time, reps per minute, count, calories and scan. It folds after use and measures 92.5 x 38 x 98.5 cm unfolded. Either way, judge this one on the frame, not the number. A £39.99 alloy-steel ab machine claiming 200 kg asks you to trust copy over engineering. It makes sense for a light user in a flat who wants a folding frame and a counter; it does not make sense as the household's main piece of kit. Pros: £39.99 — the cheapest item on this list; 5 frame-height settings to change the incline; LCD shows time, reps per minute, count, calories and scan; Folds for storage; 92.5 x 38 x 98.5 cm unfolded; Alloy steel frame stated Cons: Only 40 ratings at 4.3; 440 lb capacity claim on a £39.99 frame; 8% one-star ratings despite the small sample; No warranty stated ### 10. TYRSEN Ab Machine, 200 kg Load, 2-Year Warranty - Price: £60.99 | Amazon rating: 4.8 from 22 ratings - Full review: https://www.ranked10.co.uk/fitness/best-ab-machines/tyrsen-ab-machine - Buy on Amazon: https://www.amazon.co.uk/dp/B0GH7F6LLG?tag=ranked10-21 The highest rating in the list, 4.8, rests on just 22 reviews — but the 200 kg dual-track frame carries a 2-year warranty. Tenth despite the highest rating here, 4.8. That figure comes from 22 ratings, and 24% of them are four-star rather than five — there are no one-star or two-star scores at all. With a sample that small, a 4.8 tells you less than the 4.6 from 2,158 at the top of this list. It states 200 kg / 440 lbs from a reinforced steel triangular dual-track frame, with four height settings, silent rollers, thick foam padding and an LCD. The listing positions it as a core trainer for home gym use rather than commercial kit, and it carries a 2-year manufacturer warranty plus a lifetime parts promise — the longest cover stated here. In theory a lifetime-parts promise outlasts the machine; in practice it depends on the seller still trading. Worth noting too that it ranks 8,144 in Sports & Outdoors and 10th in Strength Training Upper Body Machines on only 22 reviews. Buy it for the warranty and the dual-track frame, not the 4.8. Pros: 200 kg / 440 lbs stated on a dual-track reinforced steel frame; 2-year manufacturer warranty plus lifetime parts support; 4 height settings and a silent roller system; Rank 8,144 in Sports & Outdoors; 10th in Strength Training Upper Body Machines; 4.8 average Cons: Only 22 ratings — the smallest sample here; 4.8 rests on 22 reviews, not hundreds; 24% of its ratings are four-star, not five; Lifetime-support promise depends on the seller continuing to trade ## Verdict For most homes, the £65.99 MERACH earns top spot on volume alone — 2,158 ratings at 4.6 — but it lists no warranty, so buy it knowing that. If a stated load limit matters more to you, take the £70 dual-track MERACH, which publishes 330 lb in both bullet and spec, or the £60.99 TYRSEN at 200 kg with a 2-year warranty — albeit on only 22 ratings. If you want the cheapest way in, the £39.99 Panana folds flat; treat its 440 lb figure as copy. Either way, these ab machines for home all obey one rule: the load number in the title is marketing, and the number in the specification table is the ab machine being honest. Two of the ten do not match.
