Built for Grapplers. Open to All Who Train.

What is Renshuu?

"Renshuu" (練習) is the Japanese word for deliberate practice—the kind that happens when no one is watching. It’s the quiet work, the tired work, the notes you keep to yourself, the small improvements only you notice.

At Renshuu Republic, we believe that:

Progress is earned when no one is watching.

Whether that practice happens with Judo, Jiu-Jitsu, under a barbell, or in a garage gym after a long shift, the mindset is the same:

Show up. Do the work. One rep at a time.

Founded by Grapplers. Built for Anyone Who Trains.

Built from practice

Renshuu Republic was born in Texas in 2025. After years of training Judo and Brazilian Jiu-Jitsu, we got tired of gear and supplements made for hype instead of hard rounds.

We needed equipment that could survive:

• the grind of grip fighting and takedown entries

• the pressure of guard passes and scrambles

• the sweat of late-night strength sessions and 5AM lifts

We started designing for grapplers first—because if it survives throws, rolls, and contact, it survives almost anything.

But along the way, lifters, runners, hybrid athletes, and everyday disciplined people said:

“I train like that too.” So the Republic grew.

The Renshuu Mindset

This brand is for anyone who lives by a simple truth:

Training doesn’t care if you’re tired.

It counts:

• when you train after work

• when you squeeze in a session before the kids wake up

• when you lift even though nobody is watching

• when you don’t PR, but you show up anyway

If you’ve ever said: “It wasn’t perfect, but I got it done,” you belong here.

Born in Texas. Built for the Bold.

We design apparel and supplements for real training:

Judo & BJJ — grips, scrambles, takedowns, guard work and throws

Strength & Conditioning — iron, chalk, sweat, consistency

Hybrid Training — mats + barbells + road work

Life — family, work, responsibilities, and still finding time to train

Our products are:

• tested in dojos and on the mats

• tested in gyms, garages, and parking lots at 10PM

• tested by people who train tired, not just pose for photos

If we don’t trust it in our own training, we won’t sell it. Period.
