Hi @lmccray and welcome to Mayo Clinic Connect. Connect is a patient-to-patient community with the key focus being its members, like you. It is not designed to be a community for medical experts to give advice, but it is a place to learn from all your shared experiences, insights, suggestions, and tips. Having said that, I am so glad you found us and chose to start a discussion. I'd like to invite @thankful and @predictable to the conversation to possibly lend some insight.
I think you would benefit greatly from Cardiac Rehab or a consult with one of the physicians in that department to get regimens for daily routines, lifestyle education and support from medical staff to make sure you are on the right track. I added a link below with information surrounding it if you would like to take a look. Even if not at Mayo, there are a lot of larger facilities with the same type of programs. https://www.mayoclinic.org/tests-procedures/cardiac-rehabilitation/about/pac-20385192
Also, the American Journal of Cardiology did a study on Post-Cardiac Event Resistance Exercise Guidelines. I have included that here. https://www.sciencedirect.com/science/article/pii/S0002914905017649#fig1
Do you currently have an exercise routine that you are following? Have you consulted with your physician about it?
