HOW TO TIE YOUR JUDO BELT (OBI)
There are a bewildering number of ways to tie the belt! In Judo it should be tied and stay tied...but different methods apply to different length belts. Find the method that works for you.
At the core of Olympic Judo are the throwing techniques.
The throws are organised into families, according to whether the techniques are largely executed via the hand ('Te') , hip ('Koshi'), foot/leg ('Ashi') or where balance is sacrificed (Sutemi)
If the the throws don't work to maximum effect, the Judoka must attempt to gain victory on the ground. One standard path to victory is to hold the opponent down. Equally the Judoka must learn to escape these holds (Nige-Waza)
TURNOVERS/TRANSITIONS ON THE GROUND (NE-WAZA)
Turning an opponent from a prone or turtle position onto their back, or into a submission is an art-form in itself. Click the image, or below for good examples...
