If somebody has high heart rate (>90 at rest) it is very easy to hit the max HR during exercise even moderate. How safe is to exercise at that level?

Slowly increase...: Lack of conditioning can lead to a HR that increases rather quickly with exercise. Slowly increasing the duration & exertion with exercise - and being consistent with exercise will help lead to a lower resting HR and a slower increase. The max HR recommendations are safe; however, it isn't easy to maintain them for a length of time that would be beneficial. Build up your tolerance. ...Read more

Y would diastolic BP lower after exercise, is that normal. How quickly should your heart rate go up during exercise and how far. Is 80 high resting ra?

Yes!: Normally diastolic blood pressure will fall during exercise and for several hours afterwards. This is because off vasodilation that normally occurs. Systolic BP should always rise. However, in hypertension, the diastolic pressure will rise too, imposing an unnecessary work load on the heart. Increase in heart rate is based on exercise intensity. Normally the HR max is 220-age in years. ...Read more

Harmless: Your heart rate is harmless. You can correct it by starting a program of daily exercise. As your fitness improves, your heart rate will slow. If it's never been done, a complete blood count (to exclude anemia, common in young women), TSH (exclude thyroid xs), and echo (exclude structural heart disease) should be done. ...Read more

This is 220 minus your age. From this number you can figure out your "zones". A good workout zone is 70-85% of the maximum. Talk to your doctor or a personal trainer to figure out what's best for your health and your goals. ...Read more
