HIIT, bootcamp and karate: what the dojo adds

01The short answer

02What the two have in common

A fixed hour, a group, someone who counts and watches. The demand is intermittent rather than continuous — bursts of effort with short recoveries —, a different stimulus from running that you will recognise at once. Kihon in lines — stances, blocks, strikes and kicks repeated on a count — looks from a distance like a circuit; ido geiko, the same basics on the move, is the moment the thighs start to shake. You will not arrive unprepared. You will arrive out of breath anyway, because fitness is specific: competent distance runners regularly report the same surprise at their first session.

03What is left after the session

Here is the difference. A block of burpees has no sequel: it was done, and the next session will do another. A mawashi geri learned one day is the same the next class, better executed or not, and the examination will grade it. In the WKO Shinkyokushinkai system the dojo follows, the belt order is white (ungraded), orange, blue, yellow, green, brown, then black; each colour covers two kyu, from 10th kyu, orange, to 1st kyu, brown with one stripe. Each colour has its published material, and the colour says where a student stands in the technical programme; it does not say how long the next one will take, and this page gives no average duration. The body you build at bootcamp, you put here in the service of a movement that is learned — which the interval, by construction, does not have to offer. For the detail by colour: Belts in Kyokushin karate.

04A partner, under a rule

The second addition exists in no circuit: someone in front of you. Partner work — pads, partner core work, then kumite — is where the load is delivered by another person, and that is why the increments are set by an instructor watching both, not by whichever of the two feels fit that day. The dojo publishes the rule: kumite is only permitted when the Sensei gives permission or the instruction. An ordinary class is not a tournament; what a session contains, in order, is on What training is really like.

05The conditioning is in the examination

In the WKO Shinkyokushinkai first-year textbook, an examination covers kihon, ido geiko, kata, conditioning (knuckle push-ups, jumping squats), flexibility and kumite. You know push-ups and jumping squats; here, they are graded at the belt examination, along with flexibility. So you do not leave physical preparation behind by coming to the dojo: it changes status, from a session to a criterion.

06The effort, measured

The 2024 Adult Compendium of Physical Activities gives each described activity a MET value — a multiple of the energy spent at rest. Vigorous circuit training, with kettlebells and minimal rest, is described there at 7.5 MET, vigorous calisthenics — push-ups, burpees, battling ropes — at 7.5 as well, body-weight circuit training at 6.0, and general aerobics at 7.3. Karate at a moderate pace is described there at 10.3 MET, a beginner’s slower practice at 5.3. These values describe an activity as it was observed, not your class or your game: a beginners’ class is closer to karate’s 5.3 at a slower pace than to 10.3. Your interval classes are no less hard for it: the Compendium describes an observed activity, not your coach.

07Both in the week

Two intense activities in the same week call for spacing rather than stacking, especially in the first weeks, when adaptation is mostly tissue-level and tissues adapt at their own pace whatever the motivation. Two karate classes leave room for something else; an interval class the day before a karate class, less so. The rest is your decision. A karate class has no machines, no free weights, no open access and no individual programme: you arrive at class time, follow the group’s programme, and leave when it ends.

08On Nuns’ Island, in practice

The dojo is at 550 chemin du Golf, suite 010, on Nuns’ Island (Verdun), and also serves LaSalle, Pointe-Saint-Charles and the Sud-Ouest. Children train from age 4 to 13, adults from 14, five days a week: the schedule gives the groups and times, the pricing page the monthly rates.

The first class is a free trial, and there is nothing to buy beforehand: comfortable clothes and a bottle of water are enough — what to bring to your first class has the list.
