VOLTRA I is a 12.8 lb cable trainer. A direct-drive motor makes 5 to 230 lb of resistance electronically, so there is no stack and no plates, and the load can change shape through the rep. It locks into AnyMount mounts on any Nike Strength or Jordan Strength rack, and on a bar, a post or a tree, and tracks every rep in the Beyond+ app.

Cables wear with use. Inspect regularly and replace when worn.
Resistance profiles
In Weight Training, each profile changes how force is delivered across the rep. Percentage Control sets each one as a percentage of your working weight.
Adds load on the lowering phase.
Load builds as you move through the range.
Load starts high and eases off.
Load peaks mid-range and eases at the start and finish.
Setup
