I'm a fitness instructor, so I'd better buy a dumbbell every day. If not, do push-ups, starting at 30 every time, divide into two groups, get used to it gradually, and then gradually increase it when you are comfortable. I want to enlarge my arms and eat more beef in my diet because I want to learn street dance, but I can't eat too much. Just have a meal, and then you can buy something that is the power of holding hands, more than ten dollars. This will also make the arms thicker, which is what the teacher taught us. Eat less greasy food and do aerobic exercise, that is, run and jog 10 minutes. If you want to know other muscle knowledge, you can leave me a message.

If you have any fitness questions, you can ask our coach to answer them.
