Hi. I Am A 63 Year Old Male In Good

Hi. I am a 63 year old male in good health. I exercise daily, fairly rigorous routine. I recently purchased a heart monitor to wear during my workouts. According to the graph my max heart rate should be 156. I take 50mg of Cozaar and 5 mg of Norvasic. Shoul I lower my heart rate max because of these drugs. My bp is good 120/75 consistently. If I lower my max rate should I lowere all other rates.
