how old are you actually?
is not suitable for u to do gym to lose weight, because it wont make u lose weight, just make ur muscle stronger.
i've tried to lose weight before by going to gym, doing sit-up, pumping(tekan tubi), lifting weight. but i din get weight loss, instead my weight remain and i cant get taller.
iw as doing gyn since i was 14 yrs old. from that time, my height remain short till now.
