Give it some time. Our workouts are around 5-600 reps in 55 minutes or so making very little rest. Try to look for ways to make your workouts cardio based while lifting. Doing supersets, giant sets etc. I do cardio everyday aside from the workouts and it took some time for the metabalism to catch up and kick in but once it did, the weight started dropping like a stone.
