"Muscle building" is ambiguous. It may refer to increasing the size of your muscles (hypertrophy) or it may refer to increasing the strength of your muscles. There is a correlation between muscular size and strength, but that correlation is affected by other factors such as tendon strength and bone length.
If you are trying to increase the size of your muscles, generally the best rep range is between about 8 and 15. The double progression method is popular for bodybuilding. Use a weight that enables you to do 8 reps using perfect exercise technique. Try for 9 or 10 reps during the next training session. When you are able to do 15 reps with that weight, for the training session after that add 5 lbs. and drop back down to 8 reps. Repeat the process.
Too many reps with a light weight will not do anything. For example, think of curling a pencil one thousand times-your biceps will not get larger or stronger. So there is a point of diminishing returns-and it varies between individuals and between muscle groups in the same individual.
Typically, upper body exercises are best done with fewer reps than lower body exercises if you are going for hypertrophy. You might try to go between 6 and 10 reps for upper body and between 12 and 15 or 20 for lower body. Experiment and see what works best for you.
Ab belts increase the chances of building muscle, but will not create muscle if used with out exercise.
Exercise can increase your metabolism by burning calories and building muscle, which can help you burn more calories even when you're at rest.

It could be the increase of muscle.
muscle-building (provided you exercise).
No. Exercise is a noun (physical activity, especially muscle building; or a testing procedure).
By using your muscle you are strengthening them so all you have to do is use them to increase the strength of the muscles increase the load.
It damages your muscle. Your body then use the protein from food to repair those muscle, and adapt the muscle to be ready for the next exercise. Resulting in the increase in size.
Muscle strength is most often increased through repeated use of the muscle or exercise. Muscle strength can also be increased with a combination of exercise and diet that includes protein.
True.
