Yes, definitely listen to your doctor as everyone is different. I would actually start with Cathe's beginner/intermediate workouts once given the go ahead. I have had 2 c-sections and, believe or not, was doing ab work within 2 weeks, riding my horse and working within 4 weeks, and back to full capacity with no restrictions whatsoever at 6 weeks. This was all doctor approved. She said I was in excellent condition. I recovered very quickly. I was even picking up and carrying my son the day of surgery (once I woke up).
