Strength training and karate: what the dojo adds

01The short answer

02What strength training builds, and karate does not

What a karate class does not build is maximal strength: if you want to lift heavier, karate is not the way, and nobody serious claims otherwise. The bar progresses in fine steps, and a load does not misjudge itself; that is what the gym does best, and nothing in a karate class reproduces it. Saying so up front avoids the most common misunderstanding: nobody at the dojo will ask you to give up the squat for the belt.

03What karate adds: strength that lasts

Body weight, many repetitions, sustained effort. Stance work loads the legs isometrically for long stretches, kicking sequences are endurance work for the hips, and partner core work is about volume rather than load. What that builds is the ability to keep producing force while tired — the quality a set of five heavy reps does not train, and does not have to. The two do not compete: they answer different questions. What it builds details the cardio, strength, mobility and coordination, with the limits of each.

04A programme, not only sessions

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 — stances, blocks, strikes, moving basics, kata, kumite — and the examination is about what has been learned. 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. For someone used to a logbook of loads, it is a second measure, a technical one, which does not replace the first: Belts in Kyokushin karate gives each belt’s programme.

05The physical requirements of a grading

In the WKO Shinkyokushinkai first-year textbook, an examination covers kihon, ido geiko, kata, conditioning (knuckle push-ups, jumping squats), flexibility and kumite. In other words, knuckle push-ups, jumping squats and flexibility are graded, on the same footing as kihon and kata. A lifter arrives with a base many beginners do not have. What the programme goes looking for on top is the hips, the ankles and thoracic rotation: the mobility gains a class produces are precise because the movements demand them.

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. Power lifting or body building at a vigorous effort is described there at 6.0 MET; squats and deadlifts, at a slow or explosive effort, at 5.0; a session of several exercises at 8 to 15 reps at 3.5. 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. The gap says one thing: an hour of karate is an hour of intermittent, high effort. It does not say a strength session is worth less; it is not after the effort.

07Placing both in the week

In class, squats, core work and the repetition of sequences already provide a good share of the physical preparation — which is why Kyokushin practitioners often do less separate weight training than athletes in other combat sports. The consequence to anticipate: if the class already provides a substantial load, adding a heavy programme without moving it is how you reach your third session too sore to move properly. In the first weeks, heavy leg work the day before a class combines badly; the same work two days before, better. Where your lifting days go is for you or your coach to decide; the page offers no programme. And what the dojo does not have deserves saying once. 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.
