Stop showing up
without a plan.
OneMat is your Brazilian jiu-jitsu open mat companion: one focus per session — position, objective, constraint, and drill — plus ~30-second logging and 2–4 week cycles. Serious training, wherever you train.
OneMat structures your open mat: one clear focus per session, fast post-roll logging, and 2–4 week cycles. Deliberate practice for serious grapplers — not another video feed.
Deliberate practice, not volume
Focus, low-friction post-training capture, and block-based progression.
Three moves to
real progress.
One focus per session
Daily position, objective, learning constraint, and suggested drill.
30-second logging
Chips and counters after you roll — no long forms when you are tired.
2–4 week cycles
One position for weeks with progressive objectives and adherence.
De La Riva → back take chain
Constraint: no collar grips

“What’s my constraint again?”
One focus. Log it in 30s.
One position for two to four weeks.
Not random technique roulette — a dedicated block with progressive objectives, adherence you can see, and weekly readbacks.
Block
Half guard · knee shield — attack the far underhook
This week’s objective
Win the inside space twice per roll, then log outcomes before you leave the academy.
Voices from
the mat
I used to show up to open mat with no idea what to work on. Now I open the app, see my focus, and train with intent.
— Carlos M., Blue belt · Madrid
30 s
Onboarding and logging that respect mat time.
The 30-second log is everything. I'm dead after rolling — I'm not filling out a journal.
— Andrés R., White belt · Mexico City
Two cycles in and I noticed I was making fewer mistakes from half guard. The data doesn't lie.

Better technique retention
Deliberate focus outperforms unfocused repetition (Ericsson, Peak, 2016).
30 s
Post-training log
One-line journals boost adherence rates (Fogg, Tiny Habits, 2019).
2–4 wk
Optimal cycle length
2–4 week blocks give enough time to consolidate motor patterns (Schmidt & Lee, Motor Learning, 2019).
30 s onboarding
Belt, body type, Gi/No-Gi, weak spots, goal — conversational.
After-session readback
Effectiveness-style summary, a short observation, and a nudge for next time — from what you logged.
Weekly review
Seven-day summary and a recommendation for the week ahead.
