What is K1?

K1 is a kickboxing style originating in Japan that allows the use of punches, kicks and knees (no elbows), creating a more aggressive and continuous combat than traditional kickboxing. Its name comes from the K-1 World Grand Prix tournament, founded in 1993, which popularized this combat format worldwide.

Unlike classic Kickboxing, K1 allows more extensive knee strikes and continuous combinations without interruptions, adopting rules that favor constant action. It combines techniques from Muay Thai (especially in knee usage), Karate (fast and precise kicks) and Western boxing (punch work), resulting in an explosive and spectacular sport.

At Ryutai Viladecans we teach authentic K1 under Team Calderón's direction, with instructors specialized in national and international competition. Since 2016, we've been training fighters in Viladecans with professional technique, preparing both beginners and competitors seeking the highest level in Baix Llobregat.

Frequently Asked Questions about K1

K1 is a kickboxing style that allows more extensive knee strikes (no elbows), while traditional Kickboxing has restrictions on knee usage. K1 follows Japanese rules that favor continuous action without constant interruptions, resulting in more aggressive and dynamic combats. At Ryutai we teach both disciplines, and many students train both to become more complete fighters.

For your first K1 class you need comfortable workout clothes (t-shirt, shorts or leggings), water bottle and lots of enthusiasm. We provide the necessary equipment to try: boxing gloves, wraps, shin guards for knee protection and helmet if needed. If you decide to continue, we'll advise you on what personal equipment to purchase. We train barefoot on professional tatami.

K1 has a learning curve similar to Kickboxing, but adds the technical complexity of knees and requires better timing at close distance. At Ryutai we apply controlled progression: first you master kickboxing fundamentals (punches and kicks), then we introduce knee techniques gradually and safely. If you already have a base in Kickboxing or Muay Thai, the transition is faster. Our Team Calderón instructors adapt the pace to each student.

Absolutely. At Ryutai Viladecans we prepare fighters for K1, kickboxing and amateur/professional tournament competition in Baix Llobregat and all of Catalonia. Our Team Calderón instructors have direct ring experience and know the competitive circuit. If your goal is to compete, we'll integrate you into the competition group where we train advanced technique, intensive sparring and specific strategy.
