True Z5.4 Treadmill Review
treadmill Doctor Note :
The adjustable cushioning is the main reason to get this one over the Z5.0. If you are in this price range, $800 should be well worth it. This is the treadmill design that put True on the map.
True is the only company that has perfected the orthopedic belt system. When you combine this with their adjustable cushioning, it makes for an excellent treadmill experience.
