Hello, the information you provided is not sufficient for a complete answer but I ll try to give you my best one. You haven t mentioned your age which is very important. The same applies for smoking. Young individuals are much less likely to suffer from damaged arteries and heart disease. Your heart rate is kind of alarming. It is not normal to have that high values. You also mentioned high blood pressure. I believe that it would be potentially dangerous for you if you started before being checked by a doctor. The high blood pressure, your weight and your heart rate are not good enough. If your age if higher than 30-35 and you smoke then I would discourage you from starting exercising without a thorough medical assessment. I hope I ve addressed your concerns! If you have any more questions you can ask again. I ll be glad to help you! Kind Regards!
