student?
a) Fifty to sixty minutes, once a week
b) Twenty to thirty minutes, once a week
c) Five to ten minutes, five days a week
d) Fifteen to thirty minutes, seven days a week

Answers

D. Bc it’s not too long of a time to stretch out of your day and it’s almost everyday so your body adjusts to your body muscles being pulled. It’s good to stretch

Fifteen to thirty minutes, seven days a week. Thus, the correct option is B.

Stretching keeps the muscles flexible, strong, and healthy, and we need that flexibility to maintain a range of motion in the joints. Without it, the muscles shorten and become tight.
