Is it important to always hit the same spot with youre straight punches,for example throwing a jab/rightcross,and what is the reason for this,does it have to be the exact same spot or does it just have to be an area the size of a persons head and also would the same rules apply when hitting the body,and also am i supposed to aim for the same spot when doing punchout drills?any replies would be much appreciatd...
