Questions
before you train.

I’m Justin Lockwood, and I teach the classes myself. My background is in modern Shotokan karate, with training in Machida Karate, Brazilian Jiu-Jitsu, Judo, and Aikido. You can read more about me and how I teach on the homepage.

Good Teens is for ages 13–17. Younger students are considered case by case. Private lessons are available from age nine, with the pace and exercises shaped around the child.

Tell me a little about them before they join—what interests them, what they’re unsure about, and any previous training. We can talk through the class and whether group training or a private lesson would be a better starting point.

We practise using your voice, keeping distance, protecting yourself, and getting away, alongside physical skills. The aim is to build confidence, judgement, and more options when a situation becomes difficult. Tell me what concerns you so we can discuss a useful focus for the training.

You’re very welcome to stay and watch. During class, please let me handle the coaching so your child can focus on the practice.

Yes. Private lessons can be shared by two people or arranged for a group of three or four. Tell me their ages and experience so we can agree on a suitable format. For Good Teens, both students need to meet the class age guidance.

A parent or guardian can register for Good Teens and set up the monthly payment online. Your membership continues until you cancel.

Justin publishes the practice and student-facing notes intended for you and can share a private direct link. Your homework is personal; private coaching notes are not public.

Yes. You don’t need to bring a friend or training partner. Partner exercises are part of the class, and I’ll guide you through working with the group.

No. We start with what you can do now and choose a level of challenge that suits you. If you’ve trained before, tell me what you’ve done and what you’d like to develop.

The purpose is to protect yourself, handle yourself with confidence, and make better decisions under pressure. Training brings together balance and movement, punches and kicks, throws and takedowns, joint locks, and grappling. Partner practice develops timing, control, and judgement.

We’ll talk about your experience and goals, then get moving and practise together. I’ll introduce the exercises and coach you through them, building from what you can do.

You start with pads and supervised partner practice. Contact and intensity are introduced gradually and explained before each exercise. You can pause or decline an exercise, and we’ll build from what you can do.

No gi required. Wear comfortable training clothes you can move in and bring water. I bring the gloves and pads. We still use belts to recognise progress. I’ll tell you about any other requirements when we arrange your training.

I teach in English.

Yes. Message me before booking and we’ll talk through any adjustments you need.

Saturdays, 10:15–11:45, at Core Center, Carrer dels Sapadors, 47, Valencia. Doors open at 10:00. Please arrive by 10:10 so we can start at 10:15 sharp. The class lasts 90 minutes.

Sign up online for the ongoing weekly class. You’ll get access to your student guide straight away.

The monthly fee reserves your place in the weekly class. If you miss a class, it doesn’t become credit or carry forward to the next month. Let me know if you won’t be there.

Let me know in advance if you have a holiday planned. We can talk through what’s possible. Any flexibility needs to be agreed with me beforehand.

There’s no minimum term. Use Manage membership before your next monthly payment to stop the next renewal. Your place continues until the end of the period you’ve paid for.

Good Adults is coming soon. It will be €60/month for one weekly 90-minute class, on a different day and time from Good Teens. Ask me to let you know when it starts. Private lessons and workshops are available for adults in the meantime.

Choose private training when you want concentrated individual coaching, a timetable arranged with me, or time to work on something specific. You can book a single lesson or build regular practice with a five-lesson pack.

Yes. Train one-to-one, with a partner, or in a private group of three or four. Groups of five or more are quoted individually. The private lesson options show the prices for each format.

Adult lessons last 60 minutes. Children’s lessons last 45–60 minutes, depending on age. We’ll confirm the format when arranging the lesson.

At Core, your home, a suitable private gym, or outdoors in Valencia. We need room to move without obstacles, and the space and surface determine what we can practise. We’ll agree on the location before you book.

A workshop is a focused, two-hour experience built around your concerns, experience, and the people you bring. Weekly classes and regular private lessons give us an ongoing practice to develop over time.

Come on your own, with a partner, family, or friends. There are fixed two-hour prices for one to four people. Schools, clubs, teams, and groups of five or more can arrange a quoted format. See the workshop prices.

Tell me who’s coming through the workshop enquiry and we’ll plan it together.

• Weekly classes: €60/month for one 90-minute class each week.
• Private lessons: €30 for one lesson or €125 for five. Shared lesson prices are listed on the private lessons page.
• Workshops: from €75 total for a two-hour private workshop, with prices based on the number of people.

Weekly classes are paid online at €60/month, renewing automatically until you cancel. For private lessons and workshops, I’ll confirm the full price and send payment instructions before you book. Private lessons are paid before the lesson.

Please give at least 24 hours’ notice if you need to cancel or reschedule a private lesson. Message me as soon as you know you need to change it.

No. Five-lesson packs don’t expire. We’ll arrange lesson times together, and you can reserve a regular weekly time if that suits you.
