Dumbbells and so on are anaerobic exercises, which can play a role in shaping the body.

In the process of aerobic exercise, fat provides energy for the body through decomposition, and then it is decomposed into water and carbon dioxide, of which 80% is exhaled in the form of carbon dioxide, and less than 20% is excreted through sweat.

This is why aerobic exercise is the first choice for reducing fat.
