Dumbbell bench press is more active than barbell bench press, but its intensity is obviously lower than barbell bench press, which is not aerobic training. Even high-intensity exercise has little effect on fat consumption. Fat reduction is also non-selective, and the whole body fat will be consumed, which does not mean that only the exercise parts will burn fat. Excessive muscle exercise will only increase the risk of injury, difficulty in muscle recovery and muscle decomposition. Muscle and fat can't be transformed into each other. Some people get fat after a long rest because their bodies consume less calories, but they don't pay attention to the health of their diet, which leads to the accumulation of calories and the formation of fat.
