Has anyone got an effective sprint routine they have used for cutting purposes?
Yes, many. They depend on your level of anaerobic conditioning and muscular conditioning, and also what work you'll be doing in the gym. Too much too soon is asking for a pulled hamstring.
They do more than just sprints but you can look up crossfitendurance.com and get some good stuff. Even if you don't want to do crossfit itself just replace the crossfit workout with your normal lifting.
