It's recommended to wait between 6 and 8 weeks after delivery, before starting to train again. It's not a good idea to immediately resume sports activities as your pelvic floor muscles and abdominal muscles need to heal properly. So, if you are 2 months post-partum you should be good to go!
I would simply like to add that it's better to avoid movements that put extra stress on your pelvic floor muscle until you feel your core is back strong. Squats for example are fine, but "Plié Squats" or "Sumo Squats" (done with a wider stance) add extra pressure on your pelvic floor muscles. Same thing with lifting heavy weights, again it's better to avoid for now as it add stress on your core and pelvic floor muscles.
You can replace any exercise you can't perform by tapping on the three dots, which you'll find next to the name of the exercise.
