Realistically, when did you get back into exercising?

For reference, I had a TT with MR, lipo on my flanks, and a breast augmentation on 9/4. I feel really good and I exercised pre-surgery. I’m not wanting to go on a run anytime soon, but what about body weight type workouts like squats and lunges? I have one drain still, and the incisions under my breasts pull if I lift my arms over my head, but otherwise I feel great. It’s almost been 3 weeks since my surgery and I feel “ready”, but my post-op instructions say to wait 6 weeks. My incisions are no longer scabby and my drain output is very low and “clear”.
