Terms of Use & Safety
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
⚠️ LIMITATION OF LIABILITY
To the maximum extent permitted by applicable law:
The manufacturer and seller shall not be liable for any injury, loss, or damage arising from:
Misuse or improper use
Failure to follow instructions
Modification or alteration
Use beyond intended purpose
Failure to inspect or maintain the product
