I have been a physical therapist for 45 years and have treated patients with most diagnoses ie. Cancer , CKD etc. I now have both of these diagnoses. I have been an exerciser all my life. I now try to do what I have advised most of my career. Keep a diary of your workouts, your BP, heart rate (HR) and diet. There are so many things that can effect your BP and by keeping a diary you can help manage your health and also help your physician manage your symptoms as well. Depending on your age slow and steady wins the race. As you continue you will know what is “too much” and what is keeping you at an appropriate level of exercise. Blessings.
