Chains and Inverse Chains are two variable-resistance tools you can turn on inside Weight Training Mode. They change how resistance is applied through the movement, which makes it easier to target specific parts without changing your setup or your exercise selection.

Before you start, update VOLTRA I to the latest firmware so the menus and options match what's described here.

For a deeper walkthrough on Inverse Chains (including more programming ideas), see the official guide: .

Matching resistance to your strength curve through the rep, so the movement feels more consistent

Targeting weak points or sticking points without turning the rest of the rep into a grind

Adding variety and a new stimulus to familiar exercises without adding extra gear

You'll access both features from Weight Training Mode:

Choose Chains or Inverse Chains, then set your starting resistance

Chains increases resistance as you move deeper into the rep, like lifting with real chains at the gym.

Choose a starting resistance that feels smooth and controllable in the first half of the rep.

Adjust the Chains so the last third of the rep is challenging but still clean.

Do a light test set after changes, then fine-tune.

Movements where you want to load the finish and control the last third of the rep. Examples: rows, chest press, overhead press, triceps pressdowns.

Patterns where you're stronger as you move toward lockout or peak contraction. Examples: squats, split squats, hip hinges/deadlifts, calf raises.

Inverse Chains reduces resistance as you move deeper into the rep. It front-loads the effort early, then eases off so you can complete the rep cleanly.

Start slightly heavier than your normal flat weight so the first half feels seriously loaded.

Adjust the Inverse Chains so you can still finish the rep smoothly without stalling.

If the end feels too light, reduce the Inverse Chains effect rather than raising the start weight again.

Movements where the hardest part is early or out of the bottom. Examples: deadlift-style pulls, low rows from a dead stop, biceps curls, hinges. Training explosive intent through full range without getting stuck at the finish. Examples: explosive rows, rotational pulls, punches/press-out patterns.

Alternate between Chains and Inverse Chains on the same exercise across sets. It's a quick way to attack a lift from two different angles without changing setup.

Inverse Chains can feel like a drop set inside a single rep because resistance eases as you move through the motion. That can be useful when you want a hard start without failing early.

Start moderate. Variable resistance can feel very different from a flat weight setting.

Do a light test set any time you change Chains Type or starting resistance.

Keep reps clean. These tools work best when you control the movement rather than yanking.

Don't change mode or settings under load. Bring resistance down and return the cable to the start position first.

Stay in control of the handle. Don't let the cable snap back.

Keep your setup solid and your line of pull clear.
