Trouble losing baby weight


My son is 7 months old. I have been trying to lose the baby weight since 6 weeks PP. I have tried


-increasing fruit and vegetable intake

-decreasing calories

- tons of exercise- weekly hiits and the peloton bike 6 days a week

I have lost about 5 pounds and my stomach is just tons of loose skin. What else can I do? I’m desperate to have my clothes fit normally again. My stomach area is just a lot of flabby skin and I’m starting to get discouraged. Any tricks or tips that have helped other moms is greatly appreciated!
