Unless you’ve become Muhammad Ali over night or your opponent is abysmal, there will be times when you’re sparring or fighting that will require you to take a defensive stance as oppose to an attacking one. The basics are common sense, if you don’t want to take a heavy blow to the face you have to keep your hands up by your face to take the brunt of an impact. However, there’s more to it than this, you have to be able to bob and weave your opponent, to do this you need a good core as you will have to engage your whole body to move and avoid a blow. If your opponent is going for a body shot and it’s inevitable that it’s going to make contact than the best thing to do is to tuck your arms in tight to the body and twist your upper body so that your arm takes the blow instead of your stomach, which can in many cases be more serious than a hit to the face. In addition to this, if your opponent is lunging for a hit than you can put your glove out to contact it and divert the blow, resulting in the hit either missing or having the power removed from it. As seen in the picture above showing one of Ali’s many famous fights, he isn’t holding his hands up but this can be excused because of his speed and reaction times, if you have the speed to lean back or duck under a blow without being hit than you don’t need your hands up although for anyone other than pro’s I wouldn’t personally recommend it. With bobbing and weaving the key is to keep moving and bouncing around to dodge punches, and wait until your opponent leaves his or herself undefended momentarily and weave a hit to make contact.
