RAflex Resistance Training System
COMPREHENSIVE SAFETY DISCLOSURE, OPERATING INSTRUCTIONS & LIABILITY NOTICE

⚠️ IMPORTANT – READ BEFORE USE

Failure to read, understand, and follow all instructions and warnings may result in serious injury, permanent disability, or death.

This document forms an essential part of the product. Retain for future reference.

⚠️ CRITICAL SAFETY WARNING – HIGH-ENERGY ELASTIC SYSTEM

This product incorporates elastic resistance components capable of storing and releasing significant mechanical energy under tension.

Under certain conditions, components may:

  • Snap, rupture, or fail suddenly

  • Detach from connection points

  • Slip, shift, or release under load

  • Recoil at high velocity toward the user

These events may result in high-impact, uncontrolled force transfer to the body.

⚠️ POTENTIAL INJURIES

Documented and foreseeable injuries include:

  • Eye trauma (including hyphema, retinal injury, and vision loss)

  • Facial fractures or soft tissue injury

  • Head and neck trauma

  • Chest and upper body impact injuries

  • Lacerations, abrasions, and bruising

  • Loss of balance leading to secondary injury (falls, collisions)

Elastic recoil incidents have been widely reported to cause serious ocular injuries due to direct high-speed impact.

⚠️ INHERENT RISK STATEMENT

This product presents inherent and unavoidable risks, even when:

  • Properly assembled

  • Used as intended

  • Maintained correctly

These risks arise from:

  • Non-linear elastic force behavior

  • Material fatigue and degradation over time

  • Variability in user strength, control, and movement

  • Environmental and external factors

No elastic resistance system can be considered completely safe.

⚠️ IDENTIFIED FAILURE MODES (FORESEEABLE)

Injury may result from one or more of the following:

1. Elastic Cord Failure

  • Overstretching beyond safe elongation

  • Progressive wear or micro-damage

  • Environmental degradation (UV, heat, moisture)
    → Results in rapid snapback toward the user

2. Connection Point Failure

  • Carabiner gate failure or misclosure

  • Stitching tear-out

  • Rear ring deformation or detachment
    → Causes sudden, uncontrolled release of stored energy

3. Release Under Tension

  • User loses grip or control

  • Uneven loading or instability
    → Produces slingshot-like recoil toward the upper body

4. Abrasion or Cutting

  • Contact with sharp or rough surfaces
    → Weakens cord and leads to unexpected rupture

5. Material Fatigue

  • Repeated load cycles weaken internal structure
    → Failure may occur without visible warning

⚙️ INTENDED USE

This product is intended solely for:

  • Controlled, light-to-moderate resistance boxing-style training

It must only be used with the complete system:

  • Chest/back strap

  • Rear attachment ring

  • Wrist straps

  • Elastic resistance cord (bungee)

  • Carabiner connection

❌ STRICTLY PROHIBITED USES

DO NOT use this product for:

  • Climbing, suspension, or supporting body weight

  • Lifting, towing, or high-load resistance

  • Attachment to external anchors (doors, walls, ceilings, vehicles)

  • Explosive or extreme-force training beyond intended limits

  • Medical, rehabilitation, or therapeutic purposes

  • Commercial or high-frequency institutional use without professional oversight

Any modification, alteration, or misuse voids all responsibility of the manufacturer/seller.

⚠️ DESIGN-SPECIFIC RISK DISCLOSURE

This system routes resistance from the wrists to a rear body anchor, creating:

  • Recoil paths directed toward the head, neck, and upper torso

  • Increased severity of injury if rear anchor fails

  • Asymmetrical force risks during rotational movement

  • Concentrated load on stitching and connection points

🧷 SETUP & CONFIGURATION REQUIREMENTS

Before each use:

  • Ensure chest/back strap is secure, tight, and centered

  • Confirm rear ring is stable and properly aligned

  • Attach resistance cord only to the designated rear ring

  • Verify carabiner is:

    • Fully closed

    • Properly seated

    • Undamaged

Improper setup significantly increases risk of detachment and high-speed recoil.

⚖️ SAFE OPERATION REQUIREMENTS

  • Maintain continuous control of the system

  • Use both wrist straps evenly and symmetrically

  • Perform controlled, deliberate movements only

Avoid:

  • Sudden jerking or explosive force

  • Twisting or rotational overload

  • Uneven or one-sided loading

NEVER:

  • Release straps under tension

  • Allow uncontrolled snapback

  • Use if control cannot be maintained

📏 STRETCH & LOAD LIMITATIONS

  • Do not exceed 2–3× original cord length

  • Avoid sustained maximum elongation

  • Avoid repeated high-impact stress cycles

Elastic force increases non-linearly with stretch, meaning small increases in length can produce large increases in force and failure risk.

🔄 FORCE DISTRIBUTION WARNING

Uneven loading may:

  • Concentrate stress on a single component

  • Cause directional recoil

  • Increase likelihood of sudden failure

Rotational boxing movements significantly increase these risks.

🔍 MANDATORY PRE-USE INSPECTION

Inspect ALL components before each use:

Elastic Cord:

  • Cracks, fraying, thinning, stiffness, discoloration

Straps & Stitching:

  • Loose threads, tearing, separation, weakened seams

Rear Ring:

  • Bending, deformation, instability

Carabiner:

  • Gate malfunction

  • Cracks, bending, corrosion

DO NOT USE if any defect is present.

⏳ MATERIAL FATIGUE & SERVICE LIFE

All components are subject to:

  • Progressive wear

  • Environmental degradation

  • Fatigue from repeated stress cycles

Failure may occur suddenly and without visible warning.

Replace product immediately if:

  • Any wear is observed

  • Performance changes

  • Age or usage history is unknown

🌡️ ENVIRONMENTAL CONDITIONS

Do not use:

  • Near sharp or abrasive surfaces

  • In excessive heat or prolonged sunlight

  • In wet, slippery, or unstable environments

Environmental exposure significantly increases failure risk.

👤 USER RESPONSIBILITY

The user assumes full responsibility for:

  • Proper setup and configuration

  • Inspection before each use

  • Maintaining control during operation

  • Ensuring a safe training environment

🚫 AREA & BYSTANDER SAFETY

  • Maintain a clear safety radius at all times

  • Keep all bystanders away from the training area

  • Be aware recoil may travel beyond immediate reach

👶 USER RESTRICTIONS

  • Not for children

  • Not for unsupervised or inexperienced users

  • Not for individuals unable to safely control resistance forces

🛡️ ADDITIONAL SAFETY RECOMMENDATIONS

  • Consider wearing protective eyewear

  • Use only in controlled training environments

  • Stop immediately if:

    • Unusual stretching occurs

    • Tearing or snapping sounds are heard

    • Instability is detected
