The best time for exercise is morning and evening. Get up in the morning and do some exercise before dinner. Not too much. According to your weight, you should exercise until your arm begins to ache. Do less and do more. Do 10 times with 20kg Mega arm. Remember to be slow and don't push too hard. If you hurt a muscle and cause a muscle strain, it will take ten and a half months to recover and it will easily recur.

You can adjust it to 7.5kg at first. In fact, exercise is not about how heavy the dumbbells you practice, but how long you can last. It took a month for this exercise to take effect. I have persisted for half a year and the effect is very good. My muscles are obvious and I am full of energy in everything I do. What I want to say at dinner is that eggs are better, and those protein powders and many food additives, you know, are not as good as nature.
