Core Exercise Power Bag for Gym, 5-30 kg

The Core Exercise Bag from You vs You is the entry at number 9 in this guide. It is listed at £24.99 in the 5 kg size, and the bullets advertise a range running from 5 kg up to 30 kg for stronger lifters. The useful part is what the spec sheet does with that number: Size reads 5kg and Item Weight reads 5 kg, so on this listing the figure you see is the weight of the bag that turns up, not the load it can hold. That runs against the pattern through most of this guide, where the headline weight is a capacity.

Two details in the same listing are worth reading before you order. The bullets describe "sand-filled training bags", yet the Included Components field names only a "Core Bag" — sand is not itemised anywhere on the page — and the opening bullet talks about "adding some extra weight to your usual routine", wording you would expect on a loadable bag rather than one sold at a fixed size. The Sport Type field says Boxing, while the title and bullets also sell it for running, plyometrics, MMA and general home training. It carries 4.5 out of 5 from 42 reviews, with a star breakdown shown as 11, 27 and 62. Everything on this page comes from the Amazon listing as written, not from a bag we have filled, lifted or tested.
