I began working out again after about 5 weeks as per my doctor. He still wants me to wait about two more weeks to do any abdominals. This week I started spin classes, which I love, and burns a crazy amount of calories. If you workout in a gym, can you ask for some guidance? If you can afford it, it’s worth hiring a trainer for a few sessions to teach you technique and how to get the best out of your workout. I hope that helps and good luck!
