Learn to fall without hurting yourself. Ukemi is the art of falling. It is what you learn first in most martial arts, and what you keep working on afterwards: a badly received fall stops a practice more surely than a poorly executed technique. 103 FALLS, 252 VIDEOS Forward and backward rolls, side falls, flat falls, landings after a throw: the repertoire is filmed fall by fall, from the slow gesture to real speed. SEVERAL ANGLES AND SLOW MOTION Front, side, top depending on the fall. Slow motion returns to the moment when the body places itself — the one that decides whether the landing will be good or not. AT THE DOJO, WITHOUT A NETWORK Videos download the first time you play a module. Once the module is loaded, everything stays readable with no connection, even in a poorly covered gym. YOUR PLAYLIST Gather the falls you are working on right now and find them again in one gesture. Useful for preparing a session, or to pick up an entire family. WHO IT IS FOR For the beginner approaching their first rolls, the experienced practitioner returning to the basics, the teacher who wants to show rather than explain. Whatever the discipline: judo, aikido, jujitsu, self-defense. WHY UKEMI Falling is a skill in its own right, shared across all grappling martial arts. Well received, a fall does not hurt; badly received, it injures. It is the only technique you use at every training session. NO SUBSCRIPTION 49 videos are free to watch, with no account to create. After that, a single payment unlocks the full version, once and for all. Start with the forward roll, and take it slowly.
