I have pectus excavatum and my heart is turned in such a way that it is not able to effectively pump when I exercise. As a result I get dizzy and nauseous. I had a baby about 1 1/2 years ago and I am unable to get rid of an extra 20 pounds. How can I do that without overexerting? Don’t I need the cardio in order to lose weight?
Perhaps you cannot do the cardio, but some strength training may benefit you. Muscles are what burn off excess fat and calories. They are your furnace. If you can make your furnace bigger with strength training, your metabolism will increase and that may be the boost you need. Another booster would be to add in smaller bouts of exercise throughout the day. Not enough to go aerobic, but enough to get you a bit warm so that you get a metabolic boost. Morning is good, and perhaps again in the afternoon, strength training can do this if you don’t rest in between sets, as well as moderate walking.
