At 2 weeks PP, I was doing short daily walks (~20 min). Around 3 weeks PP, I started doing yoga classes at the gym 1-2x/week and 1 LIGHT weightlifting session (think rehab weights, high rep), and occasional walks. By 5 weeks I was doing daily hour-long walks, yoga 2x/week, and a moderate weightlifting session. Im 6 weeks PP now and back to work. I'll be increasing the weightlifting to 1-2 hours 3x/week, moderate to intense cardio 3+/wk, maintaining the daily walks after work (weather permitted), and extended hikes on weekends. I was doing 2 hour weightlifting workouts every day before the baby so this is "easy" for me. I know my way around the weightroom so I know which lifts are safer to do than others. I wouldn't necessarily suggest the same for someone that didn't know how to lift safety especially so soon after having a baby.

I had a lot of hip pain during the pregnancy and ended up getting pre-eclampsia and was on limited activity due to low fetal weight in my 3rd trimester so waiting (almost) 9 months to get back to the gym was torture.

I have to be careful though. I still get pelvic pain if I'm on my feet too much and I still have back pain along by spine so I only do safer lifts and don't arch my back. Listen to your body and welcome back to fitness

I started walking early on too, around 10 days I guess. I live right by the sea, and we have a lovely promenade, so my eldest two go on their scooters a lot, and they love going to the beach, so we're out a lot. Now it's Sept my eldest is back at school and my middle one is at nursery 3 days a week, so we do lots of walking there and back, then I take my baby for walks.

I'd wait for the 6 week check before going back to the gym. Even though I've had such easy births, I've still always waited just to be on the safe side.

You're only 4 weeks post partum so don't expect to have all your energy back yet! This is your first I take it? I think it takes a bit longer to get used to the lack of sleep first time round. By the third time I was well used to it lol.

In case you run into this situation, exercising (and the inevitable bleeding or return of the bleeding) is not concerning unless you go through an overnight type pad within an hour (and definitely if this happens a couple hours in a row).
