My heart rate goes up to 215 bpm when exercising, is this normal? i am 23 years old.

Slightly high.: According to the American Heart Association, your maximum heart rate while exercising should be about 220 minus your age. So for a 23 year old, it would be 197 beats per minute. And your target heart rate would be lower than that, about 100-170 for a 20 year old. A heart rate higher than the maximum for your age indicates you may be straining and should probably slow down.
