After a hard weight workout, your body burns more total calories during your next cardio session than if you did light weights or no weights first.

Doing a tough weight workout before jogging or cycling helps your body burn more fat while you're doing the cardio.

After doing weight lifting or short bursts of intense cardio, your body keeps burning more calories for hours afterward than it does after a long, slow jog—even if you burned the same total calories during each workout.

High-intensity resistance exercise derives a substantial portion of its energy from the creatine phosphate system and aerobic fat oxidation, particularly during rest intervals.

Both men and women burn more fat after heavy weights before cardio, even though women tend to breathe harder during the cardio than men do.

When people engage in aerobic exercise, their bodies naturally reduce energy use in other activities, such as fidgeting or digestion, which offsets about 69% of the calories burned during the workout.
