What Suji / BFR Training Actually Does (and Why I'm Using It)

Most people have never heard of BFR training (Blood Flow Restriction), so I wanted to break it down simply — because this has the potential to help a lot of people dealing with injuries, muscle loss, or chronic weakness (like me with my knee/VMO).

For context: it’s been 4 years since my last knee surgery, and rebuilding my VMO has been incredibly challenging. Traditional strength work hasn’t been enough — the muscle just wouldn’t fully activate.

A physical therapy colleague recently recommended Suji, a smart BFR device used in rehab, athletic performance, and post-surgical recovery. After trying a similar system in the past, I was blown away by how quickly it helped me activate the quad and get a pump without heavy loading.

Here’s the science:

What is BFR Training?

BFR uses specialized cuffs to temporarily restrict venous blood flow (not arterial flow) to a muscle group.This creates:

✔ Rapid muscle fiber recruitment

✔ Increased metabolic stress

✔ Growth hormone release

✔ Muscle activation at very low loads

In simple terms:You get the stimulus of heavy lifting using very light weights.

This makes it extremely useful for people who:

Have joint pain
Are post-surgery
Are rehabbing after injury
Can’t tolerate heavy loads
Experience muscle inhibition (like VMO shutdown)
Are older and need safer strength-building strategies

Why this matters for rehab

When a muscle can’t activate properly — especially after surgery — traditional strengthening often fails because the neural signal is weak.

BFR amplifies the internal demand on the muscle, forcing activation and recruitment at intensities you cannot get otherwise without heavy loading.

For someone like me who’s struggled to rebuild the VMO, this is a game changer.

Why Suji?

There are a lot of BFR devices out there, but Suji stands out because it:

Uses smart pressure calibration for safe, consistent occlusion
Adjusts based on your limb circumference and blood pressure
Has simple app-based protocols
Is used in PT clinics, sports medicine, and pro training rooms
Makes home rehab much more effective and predictable

I’ve wanted one for years but hesitated because of the cost.They’re running a good discount through tomorrow, so I finally grabbed one.

If you want to check it out

They’re offering $120 off the Arm & Leg Cuff Set + a free carry case right now:

I’ll be using this on myself, my family, and clients who need safe, low-load strength training and faster recovery.
