One arm bigger...

M

Ok, so I’m working out for about two weeks. I’m kinda lucky I start seeing results very quick since I stick to my plan and nutrition. However, I noticed one arm is toning faster than the other (I’m right handed). Even the armpit fat seems to be less on that arm. But I don’t get it. I’m doing the exact same exercises for both arms, same weights, same movements...

Any tips?🤷🏻‍♀️
