PLEASE PLEASE PLEASE HELP ME :( I WILL GIVE BRAINLIEST TO FIRST GOOD ANSWER!

Your target heart rate is like your "sweet spot" that's in between not exercising hard enough and overexerting. So you should feel pretty balenced. You shouldnt be out of breath and dying but you shouldnt feel like your just chilling in bed.

Explanation:

Your target heart rate is the range of numbers that reflect how fast your heart should be beating when you exercise. Having a higher heart rate is a good thing that leads to greater fitness and performance. During exercise you can monitor heart rate and try to reach this target zone.

Hope this help!!! :)
