Using the power of your hips: In most respects the human body is not particularly impressive in terms of generating power, but the hips and legs are a notable exception. When you can harness the power of your hips in a constructive way, you'll find your combat effectiveness greatly increases. One of the best examples of this comes when athletes use their hips effectively against attempts. Aggressively checking and stopping an opponents takedown with your hips and then pulling him onto your hips to lift and rotate him enables you to strongly takedowns and many forms of wrestling based guard sweeps. Probably the most commonly used of this is uchi mata. You'll need an connection, usually an over hook, but it's the lower body that supplies the horsepower. Learning to quickly fit your hips into and under your opponents hips provides you with a tremendous source of power that you can call on at a moment's notice and turn defense into offense
