Yes and no.
Your heart rate is going to increase a bit while your working out, its suppose too.
But its not suppose to go crazy. Thats not a good sign, and you should probably slow it down.
You should be checking your pulse and working out within your target heart rate. That will be different depending on your goals. You should w/o at 70% intensity for fat loss and about 80-85% (only if you're healthy and not without doctors consent) for strengthening your heart. To figure this out you need to get your resting heart rate by counting your pulse for 10 sec BEFORE you get out of bed in the AM....then X by 6. Use that number in the following equation.....This is an example used for a 23 yr old at 85%.
220 - 23 (age) = 197
197 - 65 (resting heart rate) = 132
132 X85% (high end) = 112.2
112.2 + 65 (resting heart rate) = 177
177 divided by 6 = 29 beats for a 10 sec count
"Working out" Covers a lot of ground. Your muscles require oxygen and fuel, your cardiovascular system delivers it, so any time you perform physical work, your heart has to speed up to fuel the effort.
You don't say HOW fast, or what you're doing, but to give you a range, my resting rate is around 40 beats per minute, but goes as high as 190 during races (running, triathlon, cycling)

Edit: for a 3-4 hour training ride, I'll hold it around 145-155, with occasional bursts as high as 170. FWIW, I'm 55 years old.
Yes. Normal resting heart rate should be 60 to 80 beats per minute. You would likely get your heart rate up over 100 and perhaps up to 120 or a bit more during a sustainable workout. Rates higher than that can occur during strength training, like weight lifting, or during some competition like when playing raquetball, but should not remain that high over any kind of time.
If your heart rate really takes off that is a cause for concern and you should consult your Doctor.
A common way to check heartrate is to find your pulse at your wrist. Count the beats in a 15 second period and then multiply by 4. That will give you your per-minute rate. 60 to 80 is normal resting. 100 to 120 is average for sustainable exercise (with some variability depending on your own fitness level and the intensity of your workout). Rates that stay at over 140 for more than a few minutes after stopping exercise are possibly an indication of a medical problem and you should probably check with your Doctor on that!
