Exercising above your target heart rate zone may
a increase change of injury
b decrease lung capacity
c increase hydration
d decrease perspiration

Option (C) is the correct answer.

Explanation:

When we exercise then we used to sweat. More we exercise more we sweat, that is, more will be loss of water from the body.

As a result, body gets dehydrated and therefore it needs to be hydrated. Hence, we feel the need to drink water.

Thus, we can conclude that exercising above your target heart rate zone may increase hydration.

because if the tool that you are using is not balanced it there would be false mass.
