A rating, and a tread that runs quiet
Weighted vests and ab wheels.
150 kg, on a stainless steel bar.
It matters more on this device than on most: a rollout puts nearly the whole body weight through one short axle at full extension. Three wheels on that shelf publish a figure and four publish none.
The listing states a tread relief designed to reduce friction, making the wheel usable on any floor and completely silent.
Low friction is also what lets the wheel roll rather than skid at the start of the movement, which is when control is lost.
The wheel count, which decides how hard the exercise is, and the wheel diameter.
10 pockets of 470 g, 600D Oxford, reflective strips

Best for: Running rather than lifting, where the reflective strips earn their place
An ab wheel on a stainless steel bar rated to 150 kg, with a tread pattern designed to reduce friction and run silently, and a knee mat included.
