Which of the following is not one of the reasons to properly warm up before exercising? a) develop overall flexibility b) increase blood flow to the muscles and increase body temp c) return heart rate to resting levels d) prevent injuries such as sprains, strains, and cramps.

c) return heart rate to resting levels

Explanation:

Warm-up before exercises is done so that the heart rate is increased gradually. The warm-up before exercising prevent any abrupt load on the heart as it might occur due to a sudden increase in demand for oxygen.  

Hence, warm-ups do not return the heart to the resting stage, rather increases its pumping action gradually.
