The decision, in short
If you may join: a seven-day free trial across all six programmes, gear lent, with no conditions. Unlimited membership is $229 a month.
If you are visiting: a $40 drop-in the academy itself aims at visitors and travellers. Twenty-one adult BJJ sessions a week, gi and no-gi split by day; the named beginner class, Day 1 Intros, runs five times a week on Tuesday, Wednesday and Thursday only, so a weekend visitor cannot take it.

Who this academy suits
The undecided beginner: a conditionless free week across six programmes, then a day-one class five times weekly and a traveler-aimed $40 drop-in. One planning fact: the beginner class never runs Fri through Mon
Why we say it: The pricing page publishes the offers verbatim; the rendered grid places the beginner class on Tue/Wed/Thu (the Saturday session dropped by the week of 2026-08-30; re-read 2026-09-02)
A gi-or-no-gi purist: the week splits by day, so an all-gi or all-no-gi week builds itself
Why we say it: The rendered grid shows the by-day split in both sampled weeks (verified 2026-07-29)
