It depends on the type of aerobics, and the structure of your weights session. Weights can be used 'aerobically', and some 'aerobic' classes are performed with weights.
If you are studying for a sports-related qualification, the 'correct' answer will be 'aerobics'. Weight training is NORMALLY taught as a brief, vigorous, 'anaerobic' (no-oxygen) exercise, which cannot 'burn' (oxidise) much fat.
In reality, the amount of fat you burn depends on the WAY you carry out the exercise. This is because different types of movement use different types of muscle fibres, and these fibres. One type is fuelled by fat, and the other is fuelled by sugar.
Gentle movements are performed by 'slow-twitch' fibres, which ONLY burn fat.
(They contain more 'mitochondria' (where the fatburning happens). They contain more 'myoglobin' (which supplies the oxygen). And they DO NOT contain 'glycolytic enzymes' (which would be needed to allow sugarburning).
If you want to add power to a movement, so that it's quicker or stronger, you do this by 'recruiting' fast-twitch fibres. These only burn sugar.
(They have lots of Glyco-enzymes, almost NO mitochondria, and very little myoglobin.)
The changeover from fat-powered movement to sugar-powered actions is easy to detect. If the movement is EFFORTLESSLY easy, then the fatburning fibres can do it without any help from the sugarburners. You can keep this kind of activity going all day, without feeling tired, because slow-fibres do not 'fatigue'.
If effort is needed, then the fast-fibres provide more power. Sugarburning movements will tire you, and the use of sugar as a fuel will make you hungry.
(fibres that can burn fat and sugar do exist, but they still need to operate gently when burning fat (it only burns slowly), and they need to burn sugar (which is explosive) if they are used vigorously)
So, if you work out for long periods, with light weights, and keep your Heart Rate low, this can burn a massive amount of fat WITHOUT using much sugar. You can reduce bodyfat in this way.
Aerobics can be performed intensively, or gently. Vigorous work uses more CALORIES, but more of those will come from sugar. The more vigorously you work, the sooner you need to stop, and the longer you need to allow for 'recovery'. Most of the recovery processes are powered by sugar, NOT fat.
(The idea that 'raised metabolism' will burn bodyfat IS A MYTH. You can only burn fat through processes that use it as fuel. 'Fat calories' and 'sugar calories are NOT interchangeable!)
So a CONTINUOUS AND GENTLE activity can end up using more calories overall, than repeated bursts of exhausting exercise. And because less sugar is used by gentle activities,
(Even at 'rest', your muscles are working, and using oxygen, so all of your 'non-exercise' movement throughout the day is 'aerobic'. Intensities below 50% of your maximum are not usually regarded as 'exercise'. This is an ignorant attitude, because it ignores all of the work done by muscles at lower intensities (which is what they are doing most of the time).
Fatburning is related to movement, NOT the vigour with which it is done. If you are constantly in motion, you will burn fat all the time. The problem with vigorous movement, is that you need to stop.

I hate to say it but aerobics. Believe it or not, I was watching this health program and they said that there is a common misconception about muscle tissue and fat. You CANNOT turn fat into muscle, that is false. You can build more lean muscle mass. Physical activity, sweating and increased circulation burns off calories and fat stores in your body. But it's the physical activity itself that helps you drop the weight and burn off fat, and cardio exercise gives you higher results than weight lifting. So, if being a lean string bean is your goal, do cardio. But if you don't want to be a Girly Man, lift weights.

The best scenario is a combination of both.
Muscles are the natural body fat burners. The toner the muscle, the more fat it can burn, even at rest! So muscles are needed to burn fat.
Cardio will speed up your metabolism, that means, it will make the energy consumption increase. Something similar to pressing hard on the gas pedal in a car.
A faster metabolism will burn more energy (calories, fat).
So a combination of both is your best bet. Two days of cardio and two days of muscle toning is a sound fitness plan.
Rest is as important for it is while the body recuperates that a lot of the fat burning process takes place, even while we sleep!

You don’t need to exercise for hours on end. Short, sharp sets of exercise will produce better results in the event you work hard. Get a skipping rope, skip for two a few minutes, do push ups for 60 seconds or so, skip for two minutes, rest for example minute. Then change the push nearly something else like sit ups in addition to do the set again. Repeat it five times and it’s a quick, effective workout that will advance results than a long work or swim.

I have just joined the gym and am using a personal trainer to help me out for the first few weeks. He says I will burn far more fat by doing weights than I will doing cardio. I was worried about building too much muscle but he reckons even with the heavy weights I'm doing it will only tone me and help me burn fat. Hope that helps :)

You don’t need to exercise for long periods of time. Short, sharp sets of exercise will produce better results in the event you work hard. Get a skipping rope, skip for two moments, do push ups for about a minute, skip for two minutes, rest first minute. Then change the push as much as something else like sit ups and do the set again. Repeat it five times and it’s a quick, effective workout that will recover results than a long manage or swim.

The latest research in this field suggests that you should combine a weight-training workout with a cardiovascular one. this brings about a process in the body called lipolysis, which is the breakdown and use of fat molecules by the body.
This research, undertaken in Canada, goes on further to say that weight-training should be done before 30mins of cardio work. weight training starts the process of lipolysis, breaking down the fat molecules,whilst the cardiovascular work utilises the fat molecules. When i tried this for myself for 6 weeks i did see a reduction of my body fat percentage.

particular it actually does. The greater muscle you get from lifting weight the quicker your metabolism would be consequently you will burn fat quicker. yet you're able to do cardio and weight lifting to get the appropriate effects. There are some good exercising consultation suppliments you need to purchase too to hurry issues up basically stay removed from steroids.

In a one-session scenario, aerobics by far.
But weights build muscle, and the more muscle you build, the more calories you burn at rest.
