Your room's craft deserves a home
Setup-to-finish chains get taught differently across freestyle, greco and folkstyle nights. New wrestlers don't know what stalling looks like in scoring. Conditioning blocks live in the coach's head. C3NTR is a quiet place to write it all down once.
Who this is for
Schools with multiple coaches
Several coaches across the week. C3NTR holds the shared standard so every drill comes from the same library.
Competition rooms
Youth, cadet, junior, senior. Content locked by level keeps each wrestler training safely at their stage.
Built for teachers, not for IT
Your head coach opens the app, taps Edit, and writes the next takedown breakdown in plain prose. The next practice, the wrestlers know the chain.
Write directly in the app
Like a notepad. New articles are drafts until you publish, so nothing goes live by mistake.
Mobile-first authoring
Edit on the phone between classes or on the way home. The same library, the same edit screen.
A working library in under an hour
Import the starter template in a few taps. Edit anything that doesn't fit. Publish when ready.
Youth, cadet, junior, senior and open
Content locked by level, in your room's progression
Tag any article with a minimum level. Youth wrestlers see stance and basic takedowns. Juniors and seniors see scrambles and the deeper game. Coaches see everything.
A glossary of wrestling terminology
Wrestling has its own vocabulary across freestyle, greco-roman and folkstyle. C3NTR's glossary holds the terms in one place: your room's preferred names, plain definitions, and the article each term appears in.
- Stance
- The stance, the balanced..
- Shot
- A shot, the explosive attack toward an opponent's legs to begin a takedown..
- Single leg
- The single leg, a takedown in which you capture and control one of your opponent's legs..
- Double leg
- The double leg, a takedown in which you change level..
- Sprawl
- The sprawl, the primary defence against a leg attack..
- Escape
- An escape, getting free from the bottom position back to your feet..
Tournaments, weigh-ins, conditioning blocks
C3NTR isn't only the library. Schedule the tournaments your wrestlers are aiming for, post weigh-in dates, and let the room see the week ahead. Announcements land on their Today tab and events sit on the calendar.
Start from our Wrestling template
A working starter with 15 articles, 2 short videos, a 8-terms glossary across 5 tags (Getting Started, Foundations, Practice, Progression, Resources). Import in a few taps, then edit anything that doesn't fit your school. Every article, term and tag is yours from the moment you import.

Common questions
Can wrestlers only see their level's material?
Yes. Tag any article with a minimum level. Youth see stance and basic takedowns. Open and senior see everything.
Does it cover freestyle, greco-roman and folkstyle?
Yes. The starter covers technique that crosses styles, with notes where rules diverge, par terre in greco, riding time in folkstyle, exposure points in freestyle.
Can my room customise the wrestling template?
Yes. Every article and tag is editable. Add your room's favoured setups, your tournament focus and your conditioning blocks.
How long does it take to set up?
Most schools have a working library in under an hour. Import the starter template in a few taps, then edit anything that doesn't fit. Starting blank takes a little longer. Allow an hour or two to write your first ten articles. Students can use the app the day you publish.
Do I have to stop using my booking system?
No. C3NTR is a knowledge library for your curriculum, terminology and progressions. Booking, billing and scheduling stay with the tools you already use.
Is there a free plan?
Yes. Seed is free forever for up to 30 students, with no credit card required. Move up to School (£39/mo) or Academy (£69/mo) when you outgrow it.
Teach a different style? Tell us.
Whether it's a specific wrestling lineage we don't list, or another discipline entirely, drop us a line and we'll add a starter template. In the meantime, the app already works for any structured curriculum, your library starts blank in a few minutes.
