Foot sweeps are an invaluable tool in Judo; minimum effort with maximum effect. The are great tactically of taking Uke’s concentration and generally off balancing. My favourite of the foot sweeps is 100% Ko Uchi Gari. The main thing with any of the techniques in Judo is timing, but even more so with the foot sweeps. Time it right and you’ll have Uke on is back. It’s one of those techniques that you know when you’re doing it right and when you’re doing it wrong.
Here my version on how its done:
With grips on Uke’s sleeve at the elbow and on his left (your right) lapel. I really fight to keep Uke’s right handed grip off; it works better (for me) if I have complete control of Uke’s right arm. An important point is that this works best if you on the move to your left. This said, you could be turn on the spot anticlockwise, either way ultimately, your looking for Uke to make a step with his right leg first in the direction you’re travelling.
Foot sweeps are intrinsically about off-balancing. These next three point are how I obtain a great factor of off-balancing.
-
Drive your hands together and drive down
-
Stand sideways on
-
Time your foot sweep right
Now this is how I would execute it and in my version, I find it effective to do all other these in unison, but obviously there are a lot of variations and situations that you find yourself in. Here is each point explained in detail:
1. Drive your hands together and drive down
You want to drive Uke down making it harder to get his / her balance. The way I think about it is pulling a rope down. Drive the hands (and what ever you’re holding) down. Pull you’re hands in close to you as you will have more strength than if they are out stretched; you’ll active more muscles and have more control thus creating a greater force downwards.
2. Stand sideways on
Your hips should be in at a 90 degree angle. This give you greater balance for the technique and puts your feet in a better place to sweep Uke’s leading foot. If your facing straight on, you’ll find yourself crossed legged and in a very weak position!
3. Time your foot sweep right
Easier said than do and this part (in my opinion) is the most important factor to pull of this move. Too soon and you’ll Uke will easily recover, too late and you Uke already has his balance which means you’ll be hitting an already planted foot.
There is a sweat spot, the right moment just before Uke puts his foot to the floor. That’s the point where he will be most vulnerable to this attack and most of balance. Sweep the foot as far away from his body as you can putting him / her right of balance.
Summary
In conclusion, if you time all these elements right you will have an awesome Ko Uchi Gari and your oponent will find themselves on the floor. And there is a great satisfaction in bring Uke to the floor with a foot sweep because they know (and you know) that you have just blitzed them with the simplest of moves.
