Hi Nicole,
I emailed my nurse at 3 weeks asking if I could go to the gym for lower body, and if I could really go for it, and she said…
“Hi Alice,
Walking on the treadmill would be fine, but it would not be a good idea to be doing any exercise that “works up a sweat”, your body is still recovering, a sweaty moist environment breeds bacteria, so to avoid complications, including infection, I would wait until 6 weeks to exercise properly.”
