Postpartum weight loss 😬

So before I was pregnant I fluctuated between like 120-130lbs just depending (I was on WW but sometimes I just gave up and did whatever lol). The heaviest I got pregnant was 180. I lost like 20 of that just having my son. I’m now at 145.5lbs. I’d say I’ve done pretty good. I mean I’ve gotten back on ww but haven’t started exercising because I didn’t do that before I was pregnant and it’s just a lot of effort honestly 😂😂

Who has any advice? Lol
