Aerobic exercise is also known as cardio exercise. It cranks up your metabloic rate to burn off excess bodyfat from your entire body.

Once that happens, you lose weight.

Aerobic exercise will not boost muscle growth.

The aerobic exercises you mentioned are fine; they won’t stimulate muscle growth; they help you to burn off fat.

For your info, exercise that boosts muscle growth is strength-training exercise with weights.

You said you don’t want to “diet” to lose weight……

However, you don’t have to “diet” – just eat right based on a well-balanced, healthy weight loss nutritious diet – you’ll see results faster and would be able to permanently keep off the excess weight.

If you just exercise but don’t eat right, you’ll be putting in more calories than what you can expense off during exercise, hence no caloric deficit = no weight loss.

The bset combination is to exercise and eat right. It never fails. Try it.

depends where you dont wanna build up muscle, the best excersise to burn fat is running

Exercise does burn fat. Try exercises that do not build muscle, such as swimming or dancing aerobics.
