So I was approved by my doctor Monday to workout again. I never asked her what I could and couldn't do as far as intensity. Pre-pregnancy and the first trimester I ran, burpees, planks, lifted weights, etc. I never asked nor did she say I couldn't do that sort of stuff. I know she said I could start with crunches and work my way up to leg lifts and roll ups. I haven't done any of those but I have been doing burpees, running, and planks again. No problem. Yesterday I did a lot at the gym doing my old vigorous exercise routine and my upper abdomen has been cramping. I can feel it 3 finger widths up from my belly button. I'm so worried about damaging my stomach muscles. It's not painful, just annoying. Im not experiencing any other problems. Could it just been too much? I've done burpees and planks this week and never noticed these cramps and it's weird that it's upper and not lower. Is it okay to keep doing those exercises?
