Plyometric Training:

Plyometrics are usually sport specific, but I can't see why you can't incorporate them into your cardio routine a few days a week in order to speed up the fat loss.
Plyometrics focus on speed and power movements. A sample routine could include:
5-10 minute warm-up with a skipping rope
5 minutes of stretching (to make sure your muscles, tendons and joints are loose)
Jump squats - 3 sets of 10
Medicine ball throws - 3 sets of 10
"Plyometric Push-ups" - 3 sets of 10

There are some things to consider though before starting a plyometric routine:
Age (low-intensity and low-volume only for athletes under the age of 13 or for athletes who squat less than 1.5 times their bodyweight)
Surface (some degree of softness is needed. Hard surfaces such as concrete should never be used)
Footwear (must have adequate cushioning and be well fitting)
Bodyweight (athletes who are over 240 pounds (109 kg) should be very careful and low-intensity plyometric exercises should be selected)
Technique (a participant must be instructed on proper technique before commencing any plyometric exercise)
