i look good when i flex, bad when i dont why?
hi, im 20 years old and weigh about 150lbs ive have been working out for a few years but i noticed that when i dont flex my body has a drooping/sagging look to it, my chest has more of a C shape, and my stomach appears bloated, just overall looks bad, but when i flex my body looks so much tighter and better, my abs really appear, i can see all 8, and i have a good dip in the middle (but when i dont flex its rounded as in a barley noticable line down the middle) and when i flex my chest it reshapes into somthing much better and the bottom has a nice horizontal line(connecting both pecs), and honestly when ever i go out to the beach or pool im always flexing and people tell me how cut i am (primarily because i have decent sized muscle for someone who is 150lbs) and im embarassed to not flex because it would look bad. how can i fix this?
I notice that when i flex my body/skin becomes much tighter, do i need to loose weight, tone my muscle for a better (non flexed) shape?
