Turbo Jammers! Question about Turbo Jam Fat Blaster...?

Shelleen advises not to use this workout on a regular basis only when you are looking to drop major fat... The only thing different about this one is it has 4 TURBO segments opposed to 1 or 2... If a person is up to it, would this dvd be safe to add as a regular part of my workout regimen? or should I use it sparingly as suggested?
