MaxStrength's Power Bag sits at number eight in this guide, and unlike several others here its listing says it arrives already filled with sand. It is offered in four weights — 5kg, 10kg, 15kg and 20kg — at £32.85, with a black and blue cover and reinforced handles, and it carries 4.4 out of 5 from 57 ratings.

The arithmetic on the page is the interesting part. The size field says 10kg. The item weight field on the same listing says 25 kg, a 15 kg gap inside a single product entry — and one of the reviews below describes training "even at 25kg", which matches the item weight field rather than the size field. The star breakdown does not line up either: 70 five-star, 19 four-star, 5 three-star and 6 one-star add up to 100 ratings, while the header states 57. Everything on this page is taken from the Amazon listing as it stands; we have not weighed, filled or tested the bag ourselves.

## Questions people ask

**Which weight does the £32.85 buy?**

The listing does not say which of the four weights named in the title — 5kg, 10kg, 15kg or 20kg — the £32.85 buys, and the size field on the same page reads 10kg.

**Does the MaxStrength bag arrive filled?**

Yes. The title calls it a Power Bag 'Filled with Sand Bag' and the included components are listed as 1x Power Bag, so it ships filled rather than as an empty shell.

**How heavy does MaxStrength say the bag is?**

The size field says 10kg and the item weight field on the same page says 25 kg — a 15 kg gap between two numbers in one listing.

**What do the 57 ratings work out to?**

The header shows 4.4 out of 5 from 57 ratings, but the star breakdown on the same page is 70 five-star, 19 four-star, 5 three-star and 6 one-star, which totals 100.

**What is the bag built for?**

The bullets list CrossFit, functional training, circuit workouts, endurance work and explosive sandbag training, plus lifting, pushing, pulling and carrying using the reinforced handles.

**What are the listed dimensions and materials?**

20 cm wide by 50 cm high, black and blue, with the outer material given as faux leather and ergonomic reinforced handles; the spec table also lists a different product code from the one in the listing's own address.
