Hello there i dont know alot about training, and that, but i used to weigh 75kg, now i weigh 60kg(normal for my age/lenght) , so im glad that i lost weight, but the problem is i still got some loose skin/fat haning on some places(like my chest), but, the problem i have right now are my chest muscles i have trained them for some time, but only the UPPER part have begun to take shape, i know it sounds weird, but the ''lower part'' of my chest muscles are not the same shaped and it looks weird, so i just need some tips for some exercises that can shape the lower part.. if there even is some?,
