i'm an assistant instructor . during classes or more specificallly during sparring there are quite a few students who are afraid to make contact. all they do is kick air. i have told them repeatedly to make some light contact at the very least touch the opponent because its the only way they are going to learn whether or not their kicks are accurately executed. i'm not asking them to knock their opponents out or throw powerful kicks. the most common excuse i'm hearing is 'it will hurt' or 'what if i hurt him/her'. this situation mostly occurs in the female students ( no offence ) and some of the primary school students. any ideas on how i can get them to overcome this fear of making contact during sparring. if they are afraid to make contact in the dojo how are they going to defend themselves on the streets if needed.
