Recently, my weight is increasing.

I have been confident in "the precision weight control", so I am a bit puzzled.

If I had to guess, I would say "muscle training".

Right now, I'm doing 20 pull-ups, 20 sit-ups, and 50 back-ups, lazily and unseriously, two sets a day, as long as I don't feel overburdened.

My body is not macho-style at all, but I believe that muscle has been manufactured under the fat.

I heard that muscle is 20% heavier than fat.

If this "hidden muscle" is not the reason, then my weight management system is out of order, which is a venerable problem.

I believe it, because the meal will be bad if I don't think so.
