Malrotated and malpositioned kidney.

Age:32, Gender: Male I have a malrotated and malpositioned right kidney from birth which is working about 10% of the normal capacity. Due to which my left kidney which is normal has grown in size to compensate for the right kidney, causing hypertension. This was diagnosed 5 years ago and I have been living a normal life with a regular medicine to manage hypertension. My blood pressure is under control. My right kidney is working at 80% of the capacity. Apart from hypertension, I do not have any other complaint. It is also well managed through regular medicine. My serum creatinine level remains 1.2 to 1.3 Height 182 cms, body weight is 85 kgs. Age 32 years. My query is whether should I do pushups or not ?. If yes then how many push ups and squats in day without and damage to kidneys. I have done them(push ups and squats) in the past but I am worried now as my age advances. How much physical exercise can I take without harming my kidneys. For BP management I am taking Losar 25 mg.
