It varies from person to person. If you have just practiced, it is recommended that the latter gradually increase the weight, rather than suddenly increase after a long time. Because the frequency of exercise is the most basic thing, if the frequency is less, you should practice your hair, so you should keep a certain amount of exercise regardless of your size and weight. This is the key. For example, there is a heavy barbell. Will lifting exercise your muscles? Obviously, it is impossible. On the contrary, if you have a pair of dumbbells that are not very heavy, you will get better in the end if you practice them every day, so quality and quantity are king.
