Is 109 heart rate normal?

Question

Today I was at the gym and while going at 3.3 miles per hour, with 9 incline I saw that my heartrate was 109.... I was sweating. I'm 125 pounds. I also noticed that when I smiled my heart rate went up to 130 but then declined when I stopped. IS THIS NORMAL.? Whats a normal heart rate?

Answer 1

for me, anything between 130 and 160 is a good heart rate for when i am doing cardio, but everybody's different!
