User Mode — Sets your resistance ceiling. Activate from the settings menu.
User Mode | Max Resistance |
Beginner (default on first activation) | 50 lbs / 22 kg |
Normal | 100 lbs / 45 kg |
Sports | 200 lbs / 90 kg |
Resistance indicator — Numbers and icons on the display illuminate when resistance is active. An unlit display means the unit is idle; lit indicates force is being applied.
Units — Weight (lbs / kg) and cable length (in / cm) are adjustable at any time from the settings menu.
Training data — VOLTRA I displays rep-level output in real time directly on the device screen: Peak Power, Peak Velocity, Mean Velocity, and Cable Velocity.
Starting cable length — Initial cable position is adjustable before each set, ensuring consistent range of motion across exercises and users.
Intense Mode — Available across modes, Intense Mode uses an alternative control algorithm that reduces dynamic motor compensation. The result is a more stable, mechanically consistent resistance feel — particularly noticeable at lighter loads and during the eccentric phase. Use it if you prefer a rawer resistance feel closer to a traditional cable machine.
Weight Training:
Weight Training:
Standard constant resistance — functions like a cable machine. The motor maintains a fixed load throughout the full range of motion with ultra-low inertia for smooth, controlled movement in both directions.
Timer — Set a custom rest interval between sets.
Smart Pin — Saves up to three frequently used resistance levels for one-tap access between exercises. Tap a saved weight to load it instantly; tap again to edit.
Damper:
Damper:
Velocity-based resistance — the harder and faster you pull, the greater the resistance. Force scales dynamically with movement speed according to the following relationship:
Resistance = Factor × Velocity
Power = Resistance × Velocity × g
The Factor parameter is user-adjustable and controls the sensitivity of the damping response.
Use it for: explosive power development, athletic conditioning, high-velocity training.
Isokinetic:
Isokinetic:
Fixes the cable speed rather than the load. VOLTRA I adjusts resistance dynamically so that movement occurs at a set velocity (0.1–1.0 m/s) regardless of the force applied. Eccentric settings are supported.
Use it for: rehabilitation protocols, neuromuscular training, controlled-velocity strength assessment.
Isometric:
Isometric:
Holds resistance at a fixed position — the cable does not move. Push or pull against immovable resistance at a specific joint angle. Maximum resistance: 400 lbs (1,779 N).
Metrics captured: Peak Force (N), Rate of Force Development (RFD) 0–100ms, Time to Peak Force, Impulse 0–100ms, Peak Relative Force (%), Test Time.
Setup:
Select Isometric from the mode menu
Input body weight for relative force calculations
Pull cable to your desired test position and hold to set
Apply maximum effort — timer starts automatically
Results display immediately on completion
Use it for: strength testing, bilateral comparison, rehabilitation assessment, return-to-sport benchmarking.

Custom Curves:
Custom Curves:
Define a fully custom resistance curve via the Beyond+ app. Set precise force values at any point along the range of motion. Saved curves can be recalled and reapplied across sessions — no reconfiguration needed.
Setup: configure via Beyond+ app → Modes → Custom Curve. Adjust force zones along the curve, save, and activate on device.
