Generally speaking, if the muscle content is high, the strength will be greater. If the muscle content is low, the strength will be less. Generally speaking, weight can determine your own strength range, and muscle determines the fluctuation of strength within this range.

If a person is big but never exercises, his strength is relatively weak, but if he exercises regularly and has muscles, his strength will be relatively greater.

There are three people in my department. Besides me, there is a big brother in his thirties who weighs 180 kg and is about 1.78 m in height. Another big brother is also in his early thirties, less than 1.75 m and weighs less than 130 kg. He is extremely thin and likes sports.

Tell me more about you and your boyfriend. Is he thin? First of all, as a man, his physique is slightly different from that of women, so he should have certain advantages, which may also be because your psychology suggests that you are timid. Although you say that he is a weak scholar, it doesn't mean that he has no fitness. If he still has muscles, he must be much stronger than you. You can do some fitness properly, such as running, cycling and lifting dumbbells.

It is understood that muscle fibers can become thicker and bigger through muscle contraction, so our muscles can gradually become stronger and stronger through exercise.

These are my views. Of course, what does it matter who is strong? Boys naturally care more about girls, instead of competing with their own strength, and girls don't have to care who is stronger with boys. Fitness is to keep fit. If you always want to conquer each other, your feelings will be affected. I hope my words can help you, thank you!
