Rapid weight gain/loss can do bad things to skin. Unfortunately, exercise doesn't fix that. If you only had a bit say, in your arms, you could possibly "fill in" the extra with muscle, but in your abs, there's not a lot you can do.
Thanks for the name calling Grey Goose.
The original post did not state the age of the poster, I did not know this person was 18. I am aware that a younger person is generally more able to rebound from such things than an older person who has been significantly overweight for decades.
At 18, wt loss of 80 pounds will probably not cause enough excessive skin to be a big problem, staying in shape and eating right will most likely take care of most, if not all of it, in time.
In the past year I've lost over 80 pounds by working out and eating better. What can I do to tighten up the extra skin, mainly around my stomach.
Hey do you mind if you can explain what you did for the 80 pounds?
Like what was your starting weight?
What kind of workout did you do?
What did you eat?
Sorry for not answering your question. I just started my own quest for weight loss, lol.
Thanks.
