Let me add another couple of caveats to MJ's response:
1) Your aircraft does have to be in the SEP class
As you have now said that it is a C-172 that is covered.
2) An instructor ihas to be willing to be PIC in your aircraft.
Insurance (or lack of) is a common reason for refusal.
ie Aircraft not insured for training, or only insured for the owner to be PIC.
