I'm not a huge fan of the idea of non-runners (which I think you are) doing "sprints," no matter how warmed up. In trying to figure out whether I can safely do speed work myself, I've consistently been cautioned to wait until I have an adequate mileage base. Now, just how adequate that base has to be is subject to debate, but some base is recommended. And even then, I need to be really careful with form, especially with overstriding. So, with that in mind, I'd proceed cautiously when it comes to sprints, and jogging/running in general, as part of your classes at NIFS.
