The Z ZHICHI 2-in-1 Leg Curl/Extension Machine, model TT02, is third in our guide to leg extension machines for home use. It is a single station that switches between lying leg curl and leg extension, priced at £300.43 and rated 4.4 out of 5 from 181 ratings. The listing describes a 50 x 50 mm carbon steel main frame pipe with 1.4 mm wall thickness, six foam pads and two cushions, 3 backrest pad positions, 2 seat cushion degrees, a 5-second function switch and a quoted 7.9 sqft of space use.

The number to look at here is the 660LBS. It appears as the machine's weight capacity and again in the spec table as a Maximum Weight Recommendation of 660 Pounds, with Tension Supported listed as 300 kg — about 661 lb, so those two figures agree with each other. Where the listing stops agreeing with itself is the plate advice: a separate bullet says weight plates should be less than 130LBS. The 660LBS is what the frame is rated to hold; the 130LBS is what the listing tells you to load on the arm. The same page also quotes the machine's own weight twice, as 21KG net in one bullet and 20 kg in the spec table. Everything on this page comes from the Amazon listing, not from any testing we carried out.

## Questions people ask

**Does the Z ZHICHI TT02 include weight plates?**

No. The listing says the set does not include the leg weights, that the machine works with 1" plates and 2" plates, and that it has a plate storage function in the middle of the machine.

**How much weight can I actually put on the machine?**

The listing says weight plates should be less than 130LBS, on the same page that claims a 660LBS weight capacity.

**Does the 660LBS figure match the 300 kg in the spec table?**

Roughly. 300 kg is about 661 lb, and the spec table also lists a Maximum Weight Recommendation of 660 Pounds, so those two agree with each other.

**What is the Z ZHICHI frame made of?**

The listing states 50*50mm carbon steel with 1.4mm thickness pipe as the main frame pipe, chosen to keep the machine steady during a workout.

**How do the 181 ratings break down?**

The five, four, three, two and one-star counts given with the listing are 71, 16, 5, 2 and 6, which adds up to 100 rather than the 181 ratings quoted on the same page.

**Is the machine sized for a full-size adult?**

The listing says the home gym leg machine is ideal for full-size adult working out and cites 3 backrest pad positions and 2 seat cushion degrees for leg extension and curl.
