I started at 6 weeks and I still lift a little ... I'm no where i used to be but the recomp gonna be wild lol
I started going back 3 months pp and started with weights that were what I was lifting in pregnancy and slowly increased
You want to be cleared first, which will usually be at your post partum check up You should start with core/pelvic floor exercises, fix any diastasis recti you may have (not everyone gets it) Once you feel comfortable you can move on to light weights & build your way up back to a full gym routine
Safe 6 to 8 weeks postpartum. As a PT id discourage Weight training for now. Definitely add in core strengthening exercises to rebuild pelvic floor and abdominal muscles
It’s going to be completely dependent on the individual sorry. I’d check with your doctor at your 6 week check who will be able to advise what is suitable- however I imagine each body and women will be different and you’ll need to build your strength back up very slowly
