For those of you who like to combine your weight training and cardio workouts, the use of power exercises would work well. Its pretty simple, but a very tough way to do your workout! Remember that cardio exercise doesn't have to be aerobic. Aerobic exercise is an activity that is done continuously for more than 2 straight minutes (like running on a treadmill). Research has proven that the heart health benefits of anaerobic exercise (short bursts like jumps or sprinting) is superior to aerobic exercise.
Between each weight training exercise set, do 30-45 seconds of jump rope, mountain climbers or squat jumps full speed. It's just that simple and that tough! Try to do the whole 45 minute to 1 hour workout without any rest between exercises. Rest 2-3 minutes after completing the circuit and repeat the circuit 1 or 2 more times. This is an advanced workout technique and is guaranteed to give you maximum fat burn and heart health.
