I am 32 years old, 5'9" and 210 lbs. I have a resting heart rate of about 93-97 and the last time my blood pressure was taken it was 121/79. Should I be concerned about my resting heart rate? For added perspective, even when I was highly athletic as a senior in High School @ 5'9" but only weighed 160 lbs, my resting heart rate was between 87 and 93. When I was in the Marine Corps and weighed approximately 180 lbs and was very active my resting heart rate was still around 90. Given that my blood pressure appears normal I was just curious as to why my resting heart rate seems so high. I have also been smoke free for 9 months but previously had been a daily smoker of about 3-5 cigarettes per day since the age of 17 or 18.
