Weight loss results/tummy toning advice

Hi everyone!

I am looking for advice on tummy toning. I have lost almost 80 lbs since having my second baby. I am totally happy with my overall results but I still have my “Mom belly”

Does anyone have any tips on toning this area of excess skin? It just kind of hangs there. Also... any tips for stretch marks. I have a ton. I am still learning

to love my stretch marks but I would also love to be able to lighten them more.

Progress pictures from November to today!!

Thanks for any advice you all have!
