Question

why should you include weight training as part of your exercise routine?
i. to increase muscle mass
ii. to increase bone density
iii. to increase flexibility
a. only i
b. only ii
c. i and iii
d. i, ii, and iii

Explanation:

Weight training is mainly for increasing muscle mass. While it can have some minor effects on bone density (but not as significant as specific bone - density - building exercises like high - impact activities in some cases), it is not typically used to increase flexibility. Flexibility is better achieved through stretching exercises. So only statement I is correct.

Answer:

A. only I
