I have to say, Joe Howard's Firefighter Fitness workout is so amazing. It will work your body and really help you lose some weight. Here's the link to his blog and you can get a copy of his "Firefighter's 21 day Rapid Fat Loss Program": http://firefighterfitnessformula.com/blog/
In his program, when he does cardio, he does it in intervals. This kicks your butt and is well worth it! We started adding in endurance runs so we can beat our mile or 30 minute records.
