Aerobic activity does burn fat but it doesn't necessarily make it better in comparison to weight lifting. When you are trying to lose weight, you essentially need both aerobic and strength training. However, the key is knowing how both work in terms of burning fat.
You will burn more fat during aerobic exercise but once you stop, the fat burning ends. When you lift weights, your muscles will continue to burn fat after your workout is over. It is important to use a combination of both types of exercise to maintain fitness.
