Rank #4 in Best Ab Machine 2026: 10 Ranked, and the 440 lb Claim Four Sellers Share
MERACH Sit Up Machine, 3 Resistance Levels, £49.99
Price and rating as shown on Amazon when we collected them. Both change.
The MERACH Ab Machine Ab Trainer is number 4 in our guide to ab machines. It sells for £49.99, carries a 4.6 rating from 194 ratings, and is a folding blue frame — 17.8 in long by 17.6 in wide — with three adjustable resistance levels, an auto-rebound action and a listed item weight of 5.2 kg.
The number worth reading twice is the weight limit. The bullet that begins "With a robust weight capacity" is cut off before it gives any figure, and the only one the listing supplies is the Maximum Weight Recommendation field: 330 lb. That is not the 440 lb that headlines several ads in this category, and the listing never explains the difference. The ratings carry their own oddity: the histogram bars add up to 100, against a stated total of 194 ratings. Everything on this page comes from the Amazon listing itself, not from any testing we have done.
How those 194 ratings break down
An average hides its own shape. This is the spread behind the 4.6 stars.

Questions people ask
How much user weight does the MERACH ab machine take?
The Maximum Weight Recommendation field says 330 lb. The bullet headed "PREMIUM INDUSTRIAL DESIGN" starts to describe a "robust weight capacity" but the sentence is cut off before any figure appears, so 330 lb is the only number the listing gives.
How many resistance levels does the MERACH sit up machine have?
Three adjustable levels, plus an auto-rebound feature, which MERACH says adapts to beginners and advanced users.
How heavy is it, and does it fold?
The Item Weight field says 5.2 kg and the bullet says 11.3 lb, which agree with each other. The same bullet says it folds in 5 seconds for storage.
What warranty comes with the MERACH ab trainer?
The Product Warranty field says 12-month. The service bullet describes 1 year warranty service and 24-hour online support.
How do the 194 ratings break down?
The histogram shows 80 five-star, 10 four-star, 7 three-star, 1 two-star and 2 one-star ratings — 100 in total, not 194. The listing offers no explanation for the gap.
Does the MERACH ab machine come with anything else?
The Included Components field lists only "Ab Machine". The support bullet mentions a "rebounder trampoline", which is not part of this product.
