ok guys I have this problem.. I used to be a kinda chunky fellow about 200lbs 5'11 and I lost a lot of weight over the summer down to about 155.. now I weigh about 165... but I have a problem with my stomach..I have loose skin and scary stretch marks, but you don't really notice them when I am standing up though... I've trying doing all kinds of situps and it still doesn't help ...what do you all do to fix this or what do you think would help? thanks for the help
