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 are best for bone strength. Lifting weights (resistance training) places stress on bones, stimulating bone growth and density increase more effectively than swimming (non - weight - bearing), brisk walking (lower - intensity weight - bearing), or jumping rope (though weight - bearing, resistance from lifting weights is more targeted for bone building).

Answer:

B. lifting weights
