  • Advanced Mode: Quick Reference

    Eccentric:

    Applies additional resistance during the eccentric phase only. On the concentric phase, resistance returns to the base weight.

    Setting: Max additional eccentric load is configurable up to unlimited under Advanced User Mode.

    Chain & Inverse chain:

    Chains — Resistance increases progressively as the cable extends, replicating the effect of adding chain weight through a lift. Load is lightest at the start and heaviest at the end of the range of motion — matching the body’s stronger mechanical position at lockout. Best suited for push-dominant movements such as bench press, squat, and overhead press.

    Setting: Max additional chains load is configurable up to unlimited under Advanced User Mode.

    Inverse Chains — The reverse of Chains mode. Resistance is highest at the start of the movement and decreases as the cable extends — loading the weaker, lengthened position and easing off at the stronger end range. Well suited for pull-dominant movements where leverage is strongest when extended and weakest at full contraction.

    Auto Load & Auto Unload

    Auto Load — In Weight Training mode, long-press the resistance number to activate. Pull the cable to your desired starting position and hold steady for 3 seconds — resistance engages automatically when stable.

    Auto Load — In Weight Training mode, long-press the resistance number to activate. Pull the cable to your desired starting position and hold steady for 3 seconds — resistance engages automatically when stable.

    Twin Mode

    Quick Cable Adjustment:

    From any active mode, pull the cable twice at normal speed to enter cable length adjustment.

  • Mastering VOLTRA I Modes and Features

    Mastering VOLTRA I Modes and Features

    VOLTRA I isn’t just a portable cable machine. The real advantage is that you can change how resistance behaves depending on what you’re training for. Change the mode and the same exercise can feel like a weight stack, a band, or even moving through water.

    This guide will give you a clear idea of what each mode is about, plus a few examples of when to use each one. Below, you can also find links to dedicated guides for each mode if you want to learn more.

    If you’re not sure where to start, default to Weight Training mode first, then branch out from there.

    Core training modes

    Weight Training Mode (default)

    Standard constant resistance, like a cable machine, with a smooth, steady feel for normal lifting and straightforward programming.
    Best for: traditional strength and hypertrophy sets where you want a predictable load from start to finish.

    Resistance Band Mode

    Resistance increases as the cable extends, just like a real exercise band. Easier at the start, hardest at the end.
    Best for: end-range challenge. Great when you want lockout to be the hard part without changing your setup.

    Damper Mode

    Velocity-based resistance that gets tougher the faster you pull. Think moving through water. Smooth and manageable when you pull steadily, heavy when you accelerate hard.
    Best for: explosive intent and conditioning, where effort can scale with speed rather than a fixed load.

    Isokinetic Mode

    Fixed movement speed. You set a target speed, and VOLTRA I adjusts the resistance so you move at that speed through the rep, like a cheat code for perfect tempo.
    Best for: controlled work where consistency matters, especially rehab-style training and repeatable output.

    Isometric Mode

    Static hold mode for pushing or pulling against resistance without movement. Useful for building or testing strength at specific joint angles.
    Best for: holds, rehab progressions, and strength assessment at key positions.

    Custom Curves

    Lets you shape resistance across the rep. You decide where the rep should feel hardest, and where it should ease off.
    Best for: targeting sticking points or matching resistance to how the movement actually feels for you.

    Rowing Mode

    Fluid, dynamic resistance tuned for high-rep endurance work. Designed to feel smooth and repeatable over lots of pulls, more like a cardio tool than a set of reps.
    Best for: steady rhythm pulls and high-rep conditioning blocks.

    A simple way to explore the modes

    Pick one movement you know fairly well (a row or press works nicely):

    Do one light set in Weight Training mode to get a baseline feel for the movement.

    Switch to a different mode and repeat at a similar effort.

    Notice what changes:

    Does the resistance build toward the end (band-like)?

    Does speed change the difficulty (water-like)?

    Does the rep speed feel “guided” (isokinetic)?

    Spend some time doing the above and you’ll get a more intuitive understanding of what’s different about each mode.

    Advanced features

    Depending on firmware and settings, you may also see features like these alongside the core modes:

    Assist Mode

    Acts like a built-in spotter. If the system senses you’re stalling mid-rep, it can reduce resistance to help you finish safely. It’s especially useful when you’re training solo.

    Eccentric

    Adds extra resistance on the lowering phase only. It can be incredibly effective, and it can also make you sore in a way you didn’t consent to. Start modestly.

    Chains and Inverse Chains

    These change resistance through the rep. Chains ramps up toward the end range, which is useful when you want to load the stronger finish and train lockout strength. Inverse Chains front-loads the rep, which is useful for targeting sticking points near the start or building strength out of the bottom.

    Auto Load and Auto Unload

    Auto Load brings resistance in automatically when you start pulling, so you don’t have to dial in the start of each set manually. Auto Unload reduces resistance when you finish or reset, so you can return to the start position without fighting tension. Try both at a light setting first so you understand how quickly they engage and disengage.

    Basic safety tips for all modes

    No matter what you’re using:

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

    Start lighter than you think when trying a new mode or feature.

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

    Keep your setup solid and your line of pull clean. The mode won’t make a difference if your anchor isn’t stable.

  • All Modes at a Glance

    Universal controls & indicators

    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:

    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.

    Resistance Band:

    Resistance increases progressively as the cable extends, replicating the ascending force curve of a resistance band.

    Configurable parameters:

    • ROM range: adjustable from 20–102 in (50–260 cm) to match your movement

    • Resistance curve selectable

    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:

    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:

    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:

    1. Select Isometric from the mode menu

    2. Input body weight for relative force calculations

    3. Pull cable to your desired test position and hold to set

    4. Apply maximum effort — timer starts automatically

    5. Results display immediately on completion

    Use it for: strength testing, bilateral comparison, rehabilitation assessment, return-to-sport benchmarking.

    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.

    Rowing:

    Fluid, dynamic resistance tuned specifically for high-repetition, endurance-style movement. Choose between open-ended training or set a target distance.

    Options:

    • Just Row — open session, no distance target

    • Distance — set a target distance and track completion

  • Isokinetic Mode

    Isokinetic Mode

    Isokinetic Mode keeps your movement at a preset speed by automatically adjusting resistance throughout the rep. Push or pull harder and resistance increases. Ease off and resistance drops. Either way, the speed stays consistent.

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

    What it’s best for

    Rehab and controlled strength training where consistent speed matters

    Clean reps without momentum or “cheating” (no swinging it through)

    Repeatable progress tracking at the same speed over time

    Where to find things on-screen

    Main screen

    Speed setting (your target movement speed)

    Base weight (minimum tension so the cable stays engaged)

    Menus

    Metrics menu: performance data for tracking output across reps and sessions

    How to use Isokinetic Mode

    Select Isokinetic Mode.

    Set a slow speed to start so you can learn the feel.

    Set a base weight so the cable stays under control and doesn’t go slack.

    Do a light test set and focus on smooth movement through the full range.

    Once it feels consistent, adjust speed based on your goal:

    Slower speeds for control, rehab-style work, and strict tempo

    Faster speeds for more athletic intent and higher output

    What the speed setting actually changes

    The speed setting is a ceiling. You can’t exceed it, even if you try. Instead, VOLTRA I changes resistance to match your effort while keeping that speed constant.

    A simple way to think about it:

    If you push harder, it gives you more resistance so the speed doesn’t increase.

    If you push less, it gives you less resistance so the speed doesn’t drop off a cliff.

    That’s why it’s useful for controlled work. You get consistent movement and consistent feedback.

    Training examples

    Example 1: Controlled rows (upper body control)

    Set a slower speed and a light base weight.

    Focus on a smooth pull and smooth return.

    If you’re tempted to yank, Isokinetic Mode removes that option. It rewards control.

    Example 2: Rehab-style presses or extensions (repeatable output)

    Choose a conservative speed and keep the range strict.

    Aim for the same quality rep every time.

    If you fatigue, resistance drops rather than forcing a sudden fail.

    Progress tracking (simple and practical)

    Pick one movement, keep the setup the same, and track one variable:

    Same speed, same setup: can you complete more reps with good form?

    Same speed, same reps: does it feel easier at the same setting?

    Same speed: do your on-screen metrics trend up over time?

    That’s the value here. Consistency makes improvements obvious.

    Tips

    Start slower than you think. The goal is control first, intensity second.

    Use a base weight that keeps the cable feeling “connected,” not floppy.

    If reps get jerky, reduce speed or base weight and rebuild smoothness.

    Safety basics

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

    Start light and do a test set when you change speed or base weight.

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

    Keep your setup solid and your line of pull clean.

  • Chains and Inverse Chains

    Chains and Inverse Chains

    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: .

    What it’s best for

    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

    Where to find it on-screen

    You’ll access both features from Weight Training Mode:

    Open Weight Training Mode

    Open the advanced features area (the same area where you find Eccentric)

    Choose Chains or Inverse Chains, then set your starting resistance

    How to use Chains

    What Chains does

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

    How to dial it in

    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.

    When Chains tends to work best

    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.

    How to use Inverse Chains

    What Inverse Chains does

    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.

    How to dial it in

    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.

    When Inverse Chains tends to work best

    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.

    Programming ideas

    Option 1: Same exercise, alternate sets

    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.

    Option 2: Built-in drop-set feel

    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.

    Tips

    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.

    Safety basics

    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.

  • Resistance Band Mode

    Resistance Band Mode

    Resistance Band Mode makes resistance progressively heavier as the cable extends, just like stretching a physical resistance band. The start of the movement feels lighter, and the end range is where it bites.

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

    What it’s best for

    Training strong finishes and end-range control (lockout strength in presses, strong finish in rows)

    Adding a different hypertrophy stimulus when you want the end range to be the hardest part

    Movements where the beginning position is the most awkward or stressful, since resistance starts lighter and builds as leverage improves

    Where to find things on-screen

    Main screen

    Base resistance adjustment (your starting load)

    Fine-tune slider (-5 to +5)

    Menus

    Progressive Range menu: Range of Motion toggle and Band Length

    Resistance menu: Auto Unload, Quick Adjust, curve options, and band behaviour settings

    How to use Resistance Band Mode

    Select Resistance Band Mode.

    Set your base resistance (starting load).

    Do a light test set and pay attention to the end range. That’s where it should feel hardest.

    Adjust the base resistance until the end range is challenging but controlled.

    Good first exercises to feel this mode:

    Lateral raises

    Squat patterns with a low line of pull

    Pressing and rowing variations where you can clearly feel the lockout

    Progressive range options

    Range of Motion (ROM)
    When ROM is on, VOLTRA I measures your first rep and maps the resistance curve to your actual movement distance.
    Best for: exercises where your rep length is consistent and you want the band tailored to your personal range.

    Band Length
    When ROM is off, resistance ramps along an absolute cable length instead.
    Best for: repeatable setups where you want the same curve every session, even if your rep length changes slightly.

    Resistance curve options

    Power Law
    Resistance rises more aggressively near lockout.
    Best for: lockout strength, end-range hypertrophy, and finishers.

    Logarithm
    Resistance ramps up early, then levels off more toward the end.
    Best for: smoother reps where you don’t want the end range to spike too hard.

    Other key settings

    Auto Unload
    Drops resistance to 0 lb based on your chosen trigger, so resets are easier between sets.

    Quick Adjust
    Sets how big each adjustment step is when you increase or decrease resistance.

    Resistance Experience (Standard vs Intense)

    Standard: smoother, more cable-like feel

    Intense: more direct feel and less forgiving if your form gets sloppy. Test the Intense option at a lighter base resistance first.

    Resistance Mode (Standard vs Inverse)

    Standard: gets heavier as you extend

    Inverse: gets lighter as you extend
    Inverse can be useful when you want more challenge early in the rep and less at lockout, or when you’re experimenting with different strength curves.

    Tips

    Treat the end range as the “true” difficulty. Set your base resistance so the last third of the rep is controlled.

    Use higher reps when you’re learning it. This mode is great for burn sets and finishers because tension builds naturally.

    For rehab-style training, keep the start light and use the curve to load the safer mid-to-end range.

    If it feels awkward, change your setup before you change your settings. Anchor height and line of pull usually matter more than the curve.

    Safety basics

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

    Do a light test set before you go heavier, and pay attention to the end range.

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

    Keep your setup solid and your line of pull clean.

  • Damper Mode (Velocity Mode)

    Damper Mode (Velocity Mode)

    Damper Mode is a velocity-based resistance mode. The faster you pull, the more resistance VOLTRA I gives you. The easiest way to understand it is that it’s like moving through water. Move smoothly and it feels manageable. Accelerate hard and it pushes back.

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

    What it’s best for

    Power and athletic training where speed is part of the goal

    Conditioning sessions where intensity scales naturally with effort

    Movements that benefit from a smooth “drag” feel (drives, pulls, punches, swings)

    Where to find things on-screen

    Main screen

    Damper level: features a vertical slider (I, II, III, IV, and so on), which sets how strongly resistance ramps with speed.

    Menus

    Resistance Experience: controls how smooth or harsh the resistance feels.

    How to use Damper Mode

    Select Damper Mode.

    Start with a low damper level and do a few reps at different speeds to learn the feel.

    Damper level controls how aggressively resistance ramps with speed:

    Lower level: lighter drag, easier to move quickly

    Higher level: heavier drag, speed work becomes demanding faster

    Once it feels solid, increase the damper level as needed. Start lower than you think. It’s easy to overshoot if you go full gas on rep one.

    Training examples

    Example 1: Sprint drives (conditioning)

    Clip in a handle or harness, set a moderate damper level, and do repeated explosive drives.

    As you fatigue and your speed drops, resistance naturally eases. That makes it great for interval-style work because intensity matches the effort or explosiveness that you’re able to exert.

    Example 2: Explosive rows or punches (power intent)

    Use a stable anchor and clean setup.

    Focus on accelerating hard while staying controlled through the full motion.

    Keep reps crisp. If speed starts to fall off, rest and repeat rather than grinding out dodgy reps.

    Safety basics

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

    Start with controlled reps before you go explosive.

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

    Keep your line of pull clear and avoid sharp edges or anything the cable can rub against.
