My daughter was breech and the NHS offered a section but I asked for them to try to turn her first. This was very simple, easy process and allowed me a straight forward home birth.
The stomach muscle issue I'm unsure on! I was slim and worked out everyday, less in pregnancy and they had no problems turning my baby. My friend, who was in the same situation, was over weight and didn't exercise had several attempts to turn her baby, both failed and she had a section.
I think it depends on factors like -
- amount of fluid around the baby
- size of the baby
