What can I do as a person living with obesity, who struggles to lose weight to help lower my risk of complications if I contract COVID-19? (are there breathing exercises I can do to strengthen my lungs)? 

Trying to eat a healthy diet avoiding high sugar drinks and sugar and fat containing snacks and with plenty of fresh fruit and vegetables will also help. If you have any obesity related diseases such as high blood pressure or Type 2 diabetes, then improving blood pressure or glucose levels might help reduce the risk of severe COVID-19. Ultimately weight loss might be needed to reduce the risk, but there is no evidence regarding this yet. No particular breathing exercises are of proven benefit. You might want to try and increase your levels of physical activity as this improves your mental and physical health.
