I recently had a major abdominal surgery (12 week's ago ) and put on 7 kilos. I've already lost 3.5 kilos but the weight loss has really slowed down and I'm getting a bit flabby. Would it be safe for me to start going to the gym and start doing some cardio to start with. I also want to do some weight training again and start body sculpting. The only places I need to watch are my lower abdomen and lower back. Any suggestions would be very helpful! Thanks
