A: You are training your muscle fibers for endurance. The demand you are putting on your body increases endurance but does not require your body to decrease its fat content as much as you would expect. In fact, training that frequently and at such high intensity may be overtraining unless you are trying to achieve a competitive endurance level.
You obviously enjoy cardio-based workouts with such dedication, but there are exercises you can do combined with your cardio that will achieve your goals.
In short, if you are doing the same thing over and over again, but are still disappointed with the results, it is probably time to change the workout routine.
