Frequently asked questions

Once properly fitted, RockCuff is designed to go on in approximately 5–10 seconds.The initial fitting may take a little longer because you are establishing the correct position, strap length and starting configuration.After that, application is simple:SLIDE ON → PULL SNUG → SECURE → DIALThere is no pump to connect, bladder to inflate, device to pair, or pressure-calculation cycle to wait for.

RockCuff uses a simple four-step process:1. POSITIONSlide the cuff into the correct proximal position—high on the arm or high on the thigh.2. SNUGPull the strap until the cuff is secure and does not slide easily. It should be snug, but not already excessively compressive.3. SECURESet the strap so your starting fit can be reproduced.4. DIALStarting from the established “0” baseline, turn the dial to the recommended setting for your limb circumference.Then assess your response during exercise and adjust if necessary.

Approximately one second.RockCuff's mechanical dial allows small pressure changes without pumps, menus, apps or electronic controls.To increase pressure:Turn the dial clockwise.To decrease pressure:Lift the dial, turn it counterclockwise, then press it back down to lock.Upper-body adjustments are approximately 3 mmHg per click, while lower-body adjustments are approximately 3.5 mmHg per click.That makes it easy to make small adjustments while training.

No electronic calibration is required.Once the cuff has been properly fitted and the strap baseline established, you can return the dial to “0” between sessions and reproduce your established starting configuration the next time you train.Your response should still be monitored during each session because hydration, exercise, body position and other physiological factors can change how BFR feels.Repeatable doesn't mean ignore feedback.

No.RockCuff contains:NO BATTERYNO CHARGERNO ELECTRONICSNO BLUETOOTHNO SOFTWAREIt is mechanically operated and ready whenever you are.

No.RockCuff does not need a phone, tablet, app, Bluetooth connection, Wi-Fi or software update to function.Set the cuff, turn the dial and train.No connection required.

Yes.RockCuff is highly portable because there is no:PumpPressure hoseBatteryChargerElectronic controllerExternal power sourcePut it in a gym bag, backpack or carry-on and take it wherever you train.HOME → GYM → CLINIC → FIELD → ROADNote for military. You can take your RockCuff with you anywhere you go. Since it does not require a network connection, you won't have to leave it behind with your other connected electronics when you travel to sensitive areas.

RockCuff can be used in many environments because it does not require power, electronics or a network connection.Depending on your program, RockCuff can be used for:Home workoutsGym trainingPhysical therapySports performanceWalkingCyclingSwimmingTravelField trainingTactical trainingThe exercise and BFR protocol should still be appropriate for the individual and environment.

For the most consistent fit and grip, direct skin contact is preferred when practical.Thin, close-fitting clothing may be acceptable when it does not interfere with cuff positioning or pressure transfer.Avoid placing the cuff over:Thick clothingJacketsBulky seamsPocketsLoose fabricMaterials that allow the cuff to slide Whatever method you use, the cuff should remain securely positioned throughout the exercise.

Yes, particularly in professional environments.RockCuff is designed for repeated use in:CLINICS • TRAINING ROOMS • TEAMS • PERFORMANCE FACILITIESBetween users, the cuff should be cleaned according to the manufacturer's instructions and individually fitted for the next person's limb circumference and appropriate setting.Never assume that one person's pressure setting is appropriate for another person.Share the equipment—not the setting.Never share your cuffs with a person unless they are familar with its use.

They can if the cuff fits each person's limb appropriately and each person understands how to use BFR correctly.However, it does not cost much to have them get their own set to avoid the hassel of reinstalling the cuff after every use.Each user needs their own:Proper cuff placementLimb measurementStarting settingExercise protocolSafety screeningIndividual assessmentA setting established for one person should not simply be copied to another.For frequent home use by multiple people, having individually fitted cuffs may be more convenient.

RockCuff was designed to remove many of the practical barriers that can make BFR difficult to implement across a clinic.FASTApproximately 5–10 seconds to apply once fitted and approximately one second to adjust.SIMPLENo pumps, pairing, charging or software.COMFORTABLEEfficient pressure distribution allows lower starting pressures than many less-efficient cuff designs.AFFORDABLEEquip multiple treatment stations without purchasing a separate electronic system for each one.PORTABLEMove easily between treatment areas, performance spaces and home programs.SCALABLEUse RockCuff in the clinic, teach the patient, and prescribe an appropriate RockCuff program for home supplementation.The easier BFR fits into the workflow, the easier it becomes to use with more appropriate patients.

Yes. This is one of the primary advantages of the RockCuff system.A clinician can:ASSESS → FIT → PERSONALIZE → TEACH → SEND HOMEThe patient can then supplement appropriate in-clinic treatment with a prescribed home BFR program.RockCuff's mechanical design eliminates the need to send home pumps, chargers, electronics or connected devices.Use it in the clinic. Teach the patient. Send it home.

RockCuff achieves pressure mechanically rather than through an electronic pneumatic system.That eliminates many components found in more complex BFR equipment:Air pumpsInflatable bladdersPressure hosesElectronic controllersBatteriesChargersWireless connectivitySensorsSoftwareFewer components can mean lower manufacturing complexity, fewer potential failure points and less equipment to maintain.RockCuff's objective is to make clinical-quality BFR more accessible without making the technology more complicated than it needs to be.

No. Cost and complexity are not the same thing as repeatability.RockCuff uses a calibrated mechanical dial that provides approximately:3 mmHg per click — upper body3.5 mmHg per click — lower bodyThat allows the user to record and reproduce settings and make small adjustments without an electronic pressure controller.The relevant question isn't:“How much technology is inside the cuff?”It's:“Can I apply, reproduce and adjust the setting I need?”

Because air is only one way to apply external pressure and its very inefficient.Pneumatic BFR systems use an inflatable bladder to convert air pressure into pressure against the limb.RockCuff replaces that system with a rigid, calibrated mechanical structure.That eliminates the need for:PUMPS • AIR BLADDERS • HOSES • CHARGING • ELECTRONICSIt also allows RockCuff to apply pressure directly and efficiently across its effective width.Different technology. Same objective: Controlled Blood Flow Restriction.

RockCuff does not use an inflatable air bladder, so there is no pneumatic bladder to puncture or lose air pressure.Like any piece of exercise or clinical equipment, RockCuff should still be inspected periodically for wear and maintained according to the manufacturer's instructions.A common complaint from users of pneumatic systems is that at least one cuff will start to "lose air" after 12 months.

All three RockCuff models use the same core rigid, calibrated, nonpneumatic technology.The primary difference is how and how often they are intended to be used.FitSportBest for: Home fitness, recreational athletes and individual users.Integrated gel and neoprene interface.ClinicProBest for: Clinicians, serious athletes and frequent use.External gel interface designed for repeated clinical and performance use.EliteProBest for: High-volume clinics, teams, tactical and elite athletes.External gel with a heavy-duty nylon strap and metal buckle for maximum durability.
