Baby Weight has to go!!

I'm late here, hoping to get some support as well. FTM in November 2017, gained 60 lbs, lost 26 in the first few weeks with no effort (was breastfeeding), but now am stalled. I started using the MyFitnessPal app again yesterday (16.5 weeks PP). I'm focusing on nutrition and exercise. I was an avid exerciser pre-baby and even up through the 2nd Trimester, but gained the bulk in the 3rd Trimester. I love spin, TRX, and cardio weight classes, so I'm committing myself at least 4 times a week and some days doing multiple classes. I did a kickboxing type class and TRX class last night... needless to say, it's going to be a long and hard journey to get back to my previous capabilities. I felt like a ton of bricks in the kickboxing class, but I left the gym feeling proud of myself because I went and did my best, even though I looked like an idiot. I'm hoping to see results soon with less sugar/carbs, more protein, and more strenuous activity. Good luck, ladies!
