First, the only way you really know if your lifts are anaerobic is with a heart monitor - unless you jog in between sets! But on to the real point...

If you use up sugar - which happens primarily during higher intensity cardio - and keep doing high intensity cardio, you won't burn fat;your body will use muscle protein for fuel. Lower intensity excercise burns primarily fat, not sugar. You can train your body to process more fat at higher levels, but that takes months of low intensity cardio, mush more time on cardio than you would ever spend lifting.

If you want to maximize an hour routine, do supersets of lifting and use sets of 12-15 reps. Do a push and pull movement during the same workout. For example, do a set of back and then go right to a set of tris, back and forth, perhaps three-four sets of each movement before moving on to the next movement. Or do chest and biceps. Shoulders and legs.

High reps and minimal rest time will get your body cranking and get your heart rate up. You'll be wasted at the end of a 45 minute session. Spend the last 15 minutes stretching (not before with lifting). Then, just do cardio only on the next day, in between lifts.

Six days a week of that and you'll be real happy with the results after 2-3 months!

Hope that helps.
