Question

select the correct answer.
which type of exercise contributes most to building strong bones?
a. swimming
b. lifting weights
c. walking briskly
d. jumping rope

Explanation:

Weight-bearing and resistance exercises place stress on bones, stimulating osteoblast activity to build denser, stronger bone tissue. Lifting weights is a high-intensity resistance and weight-bearing exercise that creates significant mechanical stress on the skeletal system, more so than the other options. Swimming is a non-weight bearing exercise, brisk walking is low-impact weight bearing, and jumping rope is impact but less targeted for overall bone building than lifting weights.

Answer:

B. lifting weights
