I joined because this annoys me so much. I had my tubes tied. After the surgery, the packet said I would workout after 2 weeks, but at my 2 week post-op the nurse said 6 weeks. I said "Even cardio?" and she said "You can walk."  I thought it was absurd because walking isn't exercise unless you're huge or disabled. I walk my dog and don't count it as part of my routine. Humans were made to walk all the fuckign time. It shouldn't be taxing.
