The LIONSCOOL Leg Extension and Curl Machine V4.0 is a plate-loaded cable machine for seated leg extensions and prone leg curls, listed at £429.99 and rated 4.4 out of 5 from 126 ratings on Amazon. It takes the top spot in this guide, and the number that puts it there is also the number that does not add up.

The title advertises a "360KG Capacity". The specification field below it reads "Tension Supported: 400LBS". 360 kg is roughly 794 lb — close to double the 400 lb the spec sheet states. This is the pattern the guide keeps running into: the headline figure describes what the frame is built to withstand, not what you can load onto the carriage for a working set. Everything on this page comes from the Amazon listing as it stands, not from a machine we assembled and loaded ourselves.

## Questions people ask

**What weight capacity does the LIONSCOOL V4.0 actually have?**

The title says 360KG and the specification field says 400LBS. 360 kg is around 794 lb, so the two figures sit close to a factor of two apart, and the listing does not explain the difference.

No. The bullet points describe it as 2" plate loadable, and the Included Components field lists only the Leg Extension / Prone Leg Curl Machine.

Assembled dimensions are given as 43"W × 57"D × 40"H, with the depth extending to 65" in the lying position for leg curls.

The specification lists Number of Packs: 2, and one reviewer reports the two boxes turning up separately, by different couriers, a couple of hours apart.
