Plenty of adults step onto a mat for the first time after 40, often after taking their children to class. Judo, karate and aikido all take these beginners in their adult sessions, and two of them even run age-group competitions. What changes with age is the way back into training: recovery is slower, knees and shoulders need care, and the club matters as much as the discipline. The rules quoted here are those of the French federations; elsewhere, ask your club what your national body requires.
Medical checks
In France, since 2022 each federation decides whether an adult needs a medical certificate. The judo federation asks for one with a first adult licence, at 18, then at 30, 35, 40 and every five years after that; in other seasons a health questionnaire is enough. The karate federation has not required a certificate since 2022, subject to conditions set out on its website. Only combat sports that allow knockouts in competition require a certificate every year.
After years without exercise, a visit to your doctor makes sense even when nobody asks for it. If you have a long-term condition, ask what kind of activity suits you and at what intensity.
Aikido: no competition, no opponent
Aikido is practised in pairs: one partner attacks, the other evades and leads the attack into a throw or a joint lock, then the roles swap. The main schools do not compete; only the Shodokan style holds matches. Progress is measured through gradings. In France, the first dan requires you to be 15, hold first kyu, have three seasons of membership and have attended three federation courses in the previous twelve months.
Circular movement and body positioning matter more than strength, which is why so many people of 50 or 60 train. Tell your instructor two things at your first class. Forward and backward falls (ukemi) are taught from the start, so ask to learn them at your own pace. And kneeling techniques (suwari-waza) are hard on the joints.
Judo: from taiso to veterans' championships
Judo is built on throws and groundwork, so you will learn to fall, which takes a beginner of 45 a few weeks. Many clubs also run taiso, gentle conditioning with no throws, aimed at people who have been inactive or are overweight. It is a good way in.
If you want to compete, there is a circuit for you. The French veterans' championship is open from age 30, in five-year bands: 40 to 44, 45 to 49 and so on up to 70 and over. From 60, chokes are banned and contests drop from 3 minutes to 2 minutes 30. To enter in 2026-2027 you need a green belt, two years of membership and two approved veterans' tournaments in the season. A 40-year-old beginner should therefore allow at least two seasons.
Karate: from kata to health karate
Karate offers two paths. Kata, a set sequence against imaginary opponents, is practised alone at your own speed and trains memory as much as balance. Sparring (kumite) is done with a partner under rules on controlling your strikes; its intensity varies a lot between clubs.
The French karate federation runs a veterans' championship in sparring and kata, with five age categories, for individuals and teams. The 2026 edition took place on 23 and 24 May in Béziers.
Some clubs also offer health karate, with no competition and no contact. In Paris, for instance, Ateliers KT Santé runs a seniors' class on Thursday mornings, priced according to income. A French karate licence costs 39 euros for 2026-2027, basic insurance included.
Choosing a club
Use your trial class to check three things: whether there is a session for adult beginners, how many people your age attend, and how the instructor adapts exercises for someone with a sore back or knees. A club where adults train behind 20-year-old competitors may not be the best place to start.
A basic gi (judogi or karategi) is all you need at first; in aikido the uniform is similar to judo's and the hakama is only worn from a certain grade. Ask whether the club lends one for the first few weeks.
Frequently asked questions
Is 50 too late to start a martial art?
No. Adult judo, karate and aikido classes take beginners of any age. Aikido, with no competition, and karate kata suit a late start well; judo means learning to fall, which takes a few weeks.
Do I need a medical certificate after 40?
It depends on the federation and the country. In France, the judo federation asks for one with a first adult licence and then every five years; the karate federation accepts a health questionnaire. Either way, see your doctor if you have not exercised for years.
Which martial art avoids being hit?
Aikido has no competition and relies on cooperation between partners. Karate kata is practised alone. Some clubs also offer contact-free health karate, or taiso, conditioning with no throws.
Can I compete if I start at 40?
Yes, as a veteran. In France, the judo veterans' championship requires a green belt, two years of membership and two approved tournaments in the season; the karate one has five age categories, in sparring and kata.
