YES, it hurts. But you can recover fairly quickly. I was doing cardio again after a week, and training after about 2 weeks. I had "above the muscle" implants, and my incision was through the navel, which provided lots 'o pain as it totally tore up my abs and ribs; what took the longest, training-wise was being able to hang all my weight from the pull-up bar for pull ups. I was actually able to bench press long before I could do pull ups.
