it takes whatever time it takes. the fitter you are the faster it will drop though it will always take a while to return fully to the resting rate. your resting heart rate should be somewhere in the 60s or 70s. that's the rate when you have been sitting or lying for a while. as you get fitter it could drop even lower. some athletes have resting heart rates in the 40s. mine is currently in the high 50's because i lift weights and exercise 6 days a week. hope this helps
when will my heart rate go back to normal after exercise. im 40 and havent exercised in a while. my weight is 210 and i am 5"10. when i run my heart rate go up to 176 is this normal and it takes several hours to go back to normal. are all these stats normal?
