## The Problem
I felt stuck after shattering my collarbone in 2020, losing 20 pounds of muscle.
## The Solution
Suji BFR cuffs restrict blood flow to make light weights feel heavy without cutting circulation.
## How It Works
The cuffs create temporary pressure to limit blood leaving muscles while allowing some blood flow in.
## Why It Works
Muscle fibers recruit as if lifting heavier weights, producing gains with light weights like 20-pound curls.
## Personalized Pressure
Suji adjusts pressure based on limb size, blood pressure, and placement to avoid tourniquet effects.
## The Feel
It feels like holding your breath until your face turns purple, then relief when blood returns.
## When to Use
Use for days when heavy lifting feels too much, travel, or when you need more burn with less load.
## The Trade-off
Requires medical advice, especially after surgery or for cardio or blood pressure issues.
## Key takeaway

Suji BFR cuffs create muscle growth using light weights by restricting blood flow temporarily.
