Girls, after Turkey I got back on track, it's hard to breathe and move ?? + my pre-pregnancy weight hasn't come down completely, I want my 46-49 kg. I need to lose 5-7 kg. Maybe someone has workouts? And diet? Or how do you guys lose fat? For myself it's already hard, that's why I want to. But otherwise I would have done it) It's really hard to eat.
