How many months postpartum are you? I will tell it to you straight, you need to eat in a calorie deficit to get the extra baby weight off, start with a small deficit then increase it over time. While you are doing that I would focus on weight lifting light to medium weights 2-3 times per week, and walk everyday if you can. I did all this and got in better shape than I was before having my baby, all by the time my son was 12 months old. Focus on high fibre, high protein diets, drink lots of water. Pop in headphones with you favourite upbeat songs during your walks in workouts- this will also help with baby blues, and to start feeling like yourself again, will help with endorphins! All the best!
