Hi. I am a newbie;)

Momaish

I started this app on my phone 6 weeks ago. I have lost 14lbs so far! I'm excited from the results. However, I noticed that losing so much in a short period of time has caused way more skin saggage under my arms. What kind of exercises can I do to tighten it up.....or is it even possible to get rid of that much loose skin? I've tried weights, but it seems to have made my skin hang even worse.

Some needed advice is wanted!
Thanks:smooched:
