Randori Judo training video
Info about "Randori Judo training video"
Judo emphasizes a free-style sparring, called randori, as one of its main forms of training. Part of the combat time is spent sparring standing up, called tachi-waza the key to which is moving your opponent onto one leg (kuzushi), and the other part on the ground, called ne-waza.
Sparring, even subject to safety rules, is much more alive than only practising techniques on their own, which is what jujutsuka were used to doing. Using full strength develops the practitioner’s muscles and cardio-vascular system, and the strategy and reaction time help the practitioner develop mentally. The aim is to learn to use techniques against a resisting opponent. A common saying among judoka is “The best training for judo is judo.”
